MORE ABOUT MALULA
The African marula, Sclerocarya birrea subsp. caffra, is one of the continent’s most highly-prized indigenous fruit trees. It is often the only tree in well-populated rural areas, protected by traditional custom for its abundant fruit crop and its shade. It is justly famous for its fruit, all parts of which are highly nutritious, and is known internationally as the basis for the prize-winning Amarula Cream® liqueur. The ripe fruit is collected in large quantities in rural areas for eating, making a potent beer, and for the oil-rich, highly nutritious seeds. The ripe fruits are also much sought after by elephants, who will break off large branches in their eagerness to feed on the fruit, leaves and bark, and by baboons, monkeys and many smaller mammal species.
Where do we find Marula?
The Marula occurs throughout savannah grassland and bushveld Africa, from West Africa and Ethiopia to KwaZulu-Natal. Its distribution may be linked to the spread of Iron Age farmers as they moved from East Africa southwards during the past 2500 years. Archaeological evidence shows that the fruits have been used for some 12 000 years but only more recently in KwaZulu-Natal. It first appears in cave deposits in the Durban area (eShongweni) from some 2000 years ago.
The tree favours sandy soils in frost-free areas below 1500m altitude and with an annual rainfall of 200-1400mm. Marulas are often found in groves on ridge tops in association with old kraal sites. There are only four species of Sclerocarya, all of them from tropical and southern Africa, the Marula being the most widespread.
What does it look like?
A medium-to-large tree up to 10m in height with a single stem and spreading, deciduous canopy. The bark is grey and peels off in flat, roundish discs exposing the lighter, younger bark giving the tree its typically blotchy look. The twigs are thickish, and the spirally arranged, pinnately compound leaves are borne terminally. The trees are dioecious (male and female flowers are borne on separate trees), the flowers usually appearing just before the leaves in early summer, with the large, up to 40mm in diameter, fruit ripening in February and March. The fruit falls from the tree when still green and ripens to a pale yellow on the ground. The fruit has a succulent, tart, white flesh with a strong, distinctive flavour. Inside is a walnut-sized, thick-walled two to three-chambered stone protecting the seed kernels. At the end of each chamber is a small circular tight-fitting plug which can be hooked out with a bent pin when dry.
Ecology and pests
Wildlife, from elephants to insects feed on the fruit. Some moths including the African moon moth, Argema mimosae, Family Saturniidae, breed on the tree. The tough silk pupal cases of the moon moth are used traditionally by the Swazi and Zulu people for anklet rattles by tribal dancers.
Traditional and future uses
All parts of the fruit of Marula are edible. The flavour of Marula fruit has been described as pleasant, sour-sweet, and tart. The pulp can be consumed raw or boiled into a thick, black consistency and used for sweetening porridge. The fruit pulp when boiled, strained, and then boiled with sugar makes a delicious amber-coloured jelly.
A popular, fermented alcoholic beverage is prepared from the ripe fruit. The yeast occurring naturally in the fruit is normally used for spontaneous fermentation. This beverage, commonly known as Marula beer, has approximately twice as much ascorbic acid as orange juice and thus is an excellent source of vitamin C.
The seed kernels, described as a delicacy, are commonly used to supplement diet during winter or drought periods in countries such as Angola, Tanzania and Zambia, as the oil in the seed is rich in protein. They are mixed with vegetables or meat or may be pounded and made into a cake before consumption.
The wood is used for furniture, panelling, flooring, carvings and household utensils like spoons. The inner layer of bark makes a strong rope. Drums and yokes for certain animals are made from the wood of this tree. In Namibia some people use the wood for sledges. Boats are also made from the trunk. Red-brown dye can be produced from the fresh inner bark. The gum, which is rich in tannin, is mixed with soot and used as ink. A relatively good quality rope can be made from the inner bark.
In traditional medicine the powdered bark is used for a wide variety of purposes: as treatment and prophylaxis for malaria, and treatment of dysentery, diarrhoea, rheumatism and haemorrhoids. An applied infusion of the inner bark of the Marula tree is used to alleviate pain from scorpion stings and snake bites. Roots and bark are also used as laxatives. The leaves are chewed to aid indigestion and to treat heartburn and an infusion of the leaves to treat gonorrhoea. Marula oil, made from the seed kernel, is used as a skin care oil.
Its use as a source of nutritious fruit, oil, wood, and shade, its rapid growth from seed or truncheon and its ability to tolerate climatic conditions that range from near arid (less than 200 mm of annual rainfall) to well-watered make the Marula a prime candidate for helping relieve impoverished rural life in many areas of Africa. Experimental plantings here and in Israel suggest that it has great potential as a multi-purpose food crop.
The vitamin C content of the fruit is 54 mg/100 g, which is 2-3 times that of the citrus orange. The fruit is commercially harvested and the juice extracted for making a delicate-flavoured jelly and for the production of a famous liqueur, Amarula Cream”, marketed internationally by the Cape’s Distell group.
The seeds are high in fat (56-61%), protein (28-31%), citric acid (2.02%), and also contain malic acids, sugar, phosphorus, magnesium, copper, zinc, thiamine and nicotinic acid. Protein contents of 54-70% have been reported for de-fatted nuts. The seed kernels yield oil (1 ton of fruit yields 60 I of oil) with a quality and fatty acid composition comparable to olive oil but 10 times more stable and with preservative properties which have been used for preserving meat for up to a year.
The oil has been used for lighting, cooking and as a cosmetic. The seed kernels are an excellent alternative to pecans or walnuts when making fruit or carrot cake.
The wood is light reddish-brown to whitish with no definite heartwood, soft and light (air-dry 560 kg/m3). As trees attain large diameters, the wood is preferred for mortars, pestles, bowls and various local crafts, saddles, furniture and heavy crates. In South Africa, commercial utilization of the wood was halted in 1962 when the tree was officially declared a protected species throughout the country.
WHAT’S IN A NAME?
Botanical name: Sclerocarya birrea subsp. caffra (Sond.) J.O. Kokwaro. The generic name Sclerocarya is derived from two Greek words, skleros (hard) and karyon (nut). The specific name birrea is from ‘birr1, the common name for the tree in Senegal. The subspecific name caffra refers to Kaffraria (an early colonial name for the Eastern Cape and the hinterland of South Africa).
Family name: Marulas belong to the mango family, Anacardiaceae, along with mangos, pistachios, cashews, the African Wild Plum (Harpephyllum caffrum) and the African wild currant trees and shrubs (Searsia spp., formerly in the genus Rhus). The members of the family are characterized by having a resinous sap that can be rich in turpinoids (the base for natural turpentine) which can cause severe skin, breathing and eye allergic reactions as is the case with the North American Poison Ivy (Toxicodendron radicans).
Common names: Marula (English); Morula (Tswana); Maroela (Afrikaans); umGanu (Zulu); Homeid (Arabic).

TREES AND THE SACRED
From the earliest times, trees have been the focus of religious life for many peoples around the world. As the largest plant on earth, the tree has been a major source of stimulation to the mythic imagination. Trees have been invested in all cultures with a dignity unique to their own nature, and tree cults, in which a single tree or a grove of trees is worshipped, have flourished at different times almost everywhere. Even today there are sacred woods in India and Japan, just as there were in pre-Christian Europe. An elaborate mythology of trees exists across a broad range of ancient cultures.
There is little evidence in the archaeological record of tree worship in the prehistoric world, though the existence of totems carved from wood that may have held a sacred significance is suggested by the pole topped with a bird’s body and head which appears next to the bird-headed, ithyphallic male figure in the so-called well scene at Lascaux.
In the early historical period, however, there is considerable evidence that trees held a special significance in the cultures of the ancient world. In Ancient Egypt, several types of trees appear in Egyptian mythology and art, although the hieroglyph written to signify tree appears to represent the sycamore (nehet) in particular. The sycamore carried special mythical significance. According to the Book of Dead, twin sycamores stood at the eastern gate of heaven from which the sun god Re emerged each morning. The sycamore was also regarded as a manifestation of the goddesses Nut, Isis, and especially of Hathor, who was given the epithet Lady of the Sycamore. Sycamores were often planted near tombs, and burial in coffins made of sycamore wood returned the dead person to the womb of the mother tree goddess.
The ished, which may be identified as the Persea, a fruit-bearing deciduous tree (and which, incidentally, Pausanias describes as a tree that loves no water but the water of the Nile) had a solar significance. Another tree, the willow (tcheret) was sacred to Osiris; it was the willow which sheltered his body after he was killed. Many towns in Egypt with tombs in which a part of the dismembered Osiris was believed to be buried had groves of willows associated with them.
The terraces of the Funerary Temple of Hatshepsut at Deir el-bahari (c. 1480 BCE) were planted with myrrh trees. While the inner sanctuary is located inside the cliff, the temple’s outer sanctuary of terraced gardens recreated the Paradise of Amon, an earthly palace for the Sun-god in imitation of the myrrh terraces of Punt, which was the legendary homeland of the gods. A special expedition to Punt — probably at the southern end of the Red Sea — was organized by Hatshepsut’s architect and councillor, Senmut, to get the myrrh trees. Besides the terraced gardens of myrrh trees, two sacred Persea trees stood before the now vanished portal in the wall of the entrance forecourt, while palm trees were planted inside the first court.
In perhaps a similar fashion, it is believed the ramped terraces of the Mesopotamian ziggurats were also planted with trees, and sacred trees were the principal feature of the so-called Hanging Gardens of Babylon, one of the wonders of the ancient world.
In the desert environments of Ancient Egypt and Ancient Mesopotamia trees, and especially fruit trees, assumed a special importance. The head dress worn by one of the women buried in the tomb of Queen Pu’abi at the Sumerian site of Ur (c. 2500 BCE) includes in the elaborate decoration clusters of gold pomegranates, three fruits hanging together shielded by their leaves, together with the branches of some other tree with golden stems and fruit or pods of gold and carnelian.
In Egypt, the evergreen date palm was a sacred tree, and a palm branch was the symbol of the god Heh, the personification of eternity. For later cultures, the palm branch also served as an emblem of fecundity and victory. For Christians, the palm branch is a symbol of Christ’s victory over death. It also signified immortality and divine blessings and is often seen as an attribute of Christian martyrs. It also denotes particular Christian saints such Paul the Hermit and Christopher, as well as the Archangel Michael. The palm tree is also a symbol of the garden of paradise.
Trees also figure prominently in the culture and mythology of Ancient Greece. Pausanias describes the sacred groves of Aesculapius at Epidaurus, of Argus in Laconia, and a sacred grove of plane-trees at Lerna. In the land of Colophon in Ionia was a grove of ash-trees sacred to Apollo, and a sacred grove at Lycosura included an olive-tree and an evergreen oak growing from the same root. Perhaps the most famous grove, of plane-trees, was that sacred to Zeus, known as the Altis, at Olympia.
The oak tree was also sacred to Zeus, especially the tree at the sanctuary of Zeus in Dodona which also served as an oracle; it would seem the rustling of the leaves was regarded as the voice of Zeus and the sounds interpreted by priestesses. The oak was also sacred to Pan, while the myrtle-tree was sacred to Aphrodite. In the Pandrosium near the temple known as the Erechtheum (421-405 BCE) on the Athenian Acropolis, besides many other signs and remains of Athens’ mythical past — a salt-water well and a mark in the shape of Poseidon’s trident in a rock — could also be seen a living olive tree sacred to the goddess Athena.
In several Greek myths, women and men are frequently transformed into trees: Atys into a pine tree, Smilax into a yew, and Daphne into the laurel, which was sacred to Apollo.
In numerous cases the spirit of trees is personified, usually in female form. In Ancient Greece, the Alseids were nymphs associated with groves (alsos, grove), while the Dryads were forest nymphs who guarded the trees. Sometimes armed with an axe, Dryads would punish anyone harming the trees. Crowned with oak-leaves, they would dance around the sacred oaks. The Hamadryads were even more closely associated with trees, forming an integral part of them. In India, tree nymphs appear in the form of the voluptuous Vrikshaka.
In Ancient Rome, a fig-tree sacred to Romulus grew near the Forum, and a sacred cornel-tree grew of the slope of the Palatine Hill. Sacred groves were also found in the city of Rome. According to the Roman authors Lucan and Pomponius Mela, the Celts of Gaul worshipped in groves of trees, a practice which Tacitus and Dio Cassius say was also found among the Celts in Britain. The Romans used the Celtic word nemeton for these sacred groves. A sacred oak grove in Galatia (Asia Minor), for example, was called Drunemeton. The word was also incorporated into many of the names of towns and forts, such as Vernemeton near Leicester in England.
The names of certain Celtic tribes in Gaul reflect the veneration of trees, such as Euburones (the Yew tribe), and the Lemovices (the people of the elm). A tree trunk or a whole tree was frequently included among the votive offerings placed in ritual pits or shafts dug into the ground. Other shafts had a wooden pole placed at the bottom. The Celts believed trees to be sources of sacred wisdom, and the hazel in particular was associated with wisdom by the Druids.
Perhaps not surprisingly, trees appear at the foundations of many of the world’s religions. Because of their relative rarity in the Near East, trees are regarded in the Bible as something almost sacred and are used to symbolize longevity, strength, and pride. Elements of pagan tree cults and worship have survived into Judeo-Christian theology. In Genesis, two trees — the Tree of Life and the Tree of Knowledge of Good and Evil — grow at the centre of the Garden of Eden. Scriptural and apocryphal traditions regarding the Tree of Life later merge in Christianity with the cult of the cross to produce the Tree of the Cross. The fantastic Story of the True Cross identifies the wood used for the cross in the crucifixion of Jesus Christ as being ultimately from the Tree of Knowledge of Good and Evil in the Garden of Eden. Other stories claim that Adam was buried at Jerusalem and three trees grew out of his mouth to mark the centre of the earth.
In the Old Testament, trees are also associated with the ancient Canaanite religion devoted to the mother goddess Asherah which the Israelites, intent on establishing their monotheistic cult of Yahweh, sought to suppress and replace. The cult Asherah and her consort Baal was evidently celebrated in high places, on the tops of hills and mountains, where altars dedicated to Baal and carved wooden poles or statues of Asherah (or the Asherahs; in the past Asherah has also been translated as grove, or wood, or tree) were evidently located. In Deuteronomy 12:2, the Israelites are directed to “to destroy all the places, wherein the nations whom you shall dispossess served their gods, upon the high mountains and upon the hills and under every green tree; you shall tear down their altars, and dash in pieces their pillars, and burn their Asherim with fire.”
In Ancient Assyria, contemporary with the ziggurats, trees, fruit trees especially, were associated with fertility. The significance of trees in Ancient Assyria is shown in the numerous reliefs of winged deities watering or protecting sacred trees. Sacred trees, or trees of life, were associated in Ancient Assyria with the worship of the god Enlil.
Some trees become sacred through what may have occurred in their proximity. It was under a pipal tree that Siddhartha Gautama (born 566 BCE) meditated until he attained enlightenment (Nirvana) and became the Buddha. The Bodhi or Bo (Enlightenment) tree is now the centre of a major Buddhist sacred shrine known as Bodh Gaya.
For the ancient Celts, the Yew tree was a symbol of immortality, and holy trees elsewhere functioned as symbols of renewal. A tree scarred by lightning was identified as a tree of life, and, according to Pliny, the Celtic Druids believed that mistletoe grew in places which had been struck by lightning. The Druids performed rituals and ceremonies in groves of sacred oak trees, and believed that the interior of the oak was the abode of the dead. In India, it is believed that the Brahma Daitya, the ghosts of brahmans, live in the fig trees, the pipal (ficus religiosa), or the banyan (ficus indica), awaiting liberation or reincarnarnation. Among the eight or so species of tree considered sacred in India, these two varieties of fig are the most highly venerated.
The identification of sacred trees as symbols of renewal is widespread. In China, the Tree of Life, the Kien-Luen, grows on the slopes of Kuen-Luen, while the Moslem Lote tree marks the boundary between the human and the divine. From the four boughs of the Buddhist Tree of Wisdom flow the rivers of life. The great ash tree Yggdrasil of Nordic myth connects with its roots and boughs the underworld and heaven.
In Japan, trees such as the cryptomeria are venerated at Shinto shrines. Especially sacred is the sakaki, a branch from which stuck upright in the ground is represented by the shin-no-mihashira, or sacred central post, over and around which the wooden Shrines at Ise are built. The shin-no-mihashira is both the sakaki branch and the pillar confirmed in the nethermost ground, like the heaven-tree in many Japanese legends.
Sacred forests still exist in India and in Bali, Indonesia. The holy forests in Bali are annexed to temples that may or may not be enclosed in it, such as the Holy Forest at Sangeh. The general feeling of respect and veneration for trees in India has produced a great variety of tree myths and traditions.
One of the Five Trees in Indra’s paradise (svarga-loka), which is located at the centre of the earth, is the mythic abundance-granting kalpa-vriksha. An image of the kalpa-vriksha carved in sandstone in Besnagar in Central India may originally have stood as an emblem capital on top of a monolithic pillar or stambha, possibly one of the 36 or so pillars erected by the Buddhist emperor Asoka (268-232 BCE). The pillars have been interpreted as replicas of the axis mundi. The stone kalpa-vriksha capping the pillar may therefore be identified as the Cosmic Tree or world-tree, an emblematic variation of the symbolism of the stambha as axis mundi.
Single pillars made of tree trunks called Irmensul (‘giant column’) representing the ‘tree of the universe’ were set up on hilltops by some German tribes. A highly venerated Irmensul in what is now Westphalia was cut down by the Christianizing Charlemagne in 772.
With the encouragement of Pope Saint Gregory the Great in the 6th century CE, a common practice among proselytizing Christians was to graft Christian theology onto pre-existing pagan rites and sacred places. In the case of pagan tree cults, this may initially involve the destruction of the sacred grove or the cutting down of a sacred tree. However, it would appear that frequently a church would be built on the same site, thereby co-opting it in the service of Christian conversion. The process effectively Christianized the sacred powers or energies of the original site. Examples of this include the medieval Gothic cathedral of Chartres, which was built on a site which was once sacred to the Celtic Druids (acorns, oak twigs, and tree idols in the sculptural decorations on the South Portal of the cathedral may allude to the original Druidic oak grove). And before the Druids, during the Neolithic period, the same site may have been a sacred burial mound.
Trees and Architecture
The Egyptian temple was conceived essentially as a stone model of the creation landscape. The orders of columns, however, were designed not as direct representations of plant life (the palm, lotus, and papyrus bundle), but as stone reproductions of idealized landscape features.
The palmiform column, for example, which appears already fully developed by the 5th Dynasty (2465-2323 BCE) and used constantly for the next 2000 years, shows the palm tree as a circular column as if it were the trunk of a palm tree with the topmost section ornamented with palm leaves shown as if tied with a thong around the column.
A famous passage in Vitruvius describes the origin of columns in Greek and Roman architecture as derived from tree trunks, a not entirely fanciful explanation given both the tree-like tapering of the classical column (even the flutes may be stylized representations of ribbed tree bark), and the belief that stone temples in ancient Greece were based upon earlier types made of wood. It is known for a fact that the Temple of Hera at Olympia originally had columns of oak, two of which (the others having been replaced by stone columns as they wore out) were still in place when Pausanias visited Olympia in the 2nd century CE.
A similar architectural tradition identifies the origin of Gothic pointed arches and vaults in the interlacing of tree branches, and likens the view down the nave of a Gothic cathedral to a path through a wood of tall overarching trees. The suggestion can be made that the arches and vaulting of Chartres Cathedral may deliberately resemble the path to the sacred grove that stood on the original site, with the crossing of the church symbolizing, or perhaps actually located at, the central clearing in the grove where Druidic rituals formerly took place.
