Ficus ingens, the red-leaved fig, is a fig species with an extensive range in the subtropical to dry tropical regions [2] of Africa and southern Arabia. [3] Despite its specific name, which means "huge", or "vast", it is usually a shrub or tree of modest proportions. [4] It is a fig of variable habit depending on the local climate and substrate, typically a stunted subshrub on elevated rocky ridges, or potentially a large tree on warmer plains and lowlands. In 1829 the missionary Robert Moffat found a rare giant specimen, into which seventeen thatch huts of a native tribe were placed, so as to be out of reach of lions. [5] [note 1] [note 2]

Distribution and habitat

It is widespread in northern and eastern sub-Saharan Africa, [6] with a more or less contiguous range from Senegal in the west, eastwards to Eritrea, and southwards to the Eastern Cape, South Africa. It is extant in the Saharo-montane woodlands of the Tassili n'Ajjer, the Hoggar, Aïr and Tibesti mountains, and the Kerkour Nourene massif. [2] It is also found in southernmost Oman, mainly in the region south of Dhofar, called Salalah. It is found on rock faces and outcrops, rocky slopes, riparian and wadi fringes, and in dense woodlands. [4] Substrates include lava flows, coral and limestone in drier, exposed areas, [2] and sandstone or dolomite in bushveld. [7]

The smooth and leathery, dull-green leaves are narrowly ovate oblong, bright red brown when young, [8] with conspicuous yellow veins that are prominent beneath [9] and loop along the leaf margin. [5] A leaf measures some 16.5 by 8.5 cm, [5] with the base mostly square [4] or cordate, [8] sometimes broadly rounded, and the apex tapering to a blunt point. [10] Old leaves turn to a reddish-copper colour in autumn. [9]

The almost spherical figs are produced year-round but mainly in summer. [5] They are 0.9 to 1.2 cm [11] in diameter and carried on very short stalks, just below or among the terminal cluster of leaves. [10] They ripen first to a white and eventually a purple [8] or yellowish-brown colour. [9]

The smooth bark is pale grey, while younger branches have a yellow tinge. [10] Bruised or cut stems and leaves exude a non-toxic, milky latex. [9]

Habit and variation

It is deciduous or semi-deciduous and may form a subshrub or shrub, or may form a rounded crown, upwards of 5 meters tall, in sheltered conditions. [9] In the warm lowveld they may form a spreading canopy up to 15 meters tall, with a bole 2 meters in diameter. [10] In the Magaliesberg and Witwatersrand bankenveld they typically straddle boulders or are closely pressed to sunny, north to west-facing (in southern hemisphere) rock faces. Plants of the Eastern Cape are more tomentose. [9]

Uses and species interactions

In northern Nigeria the figs, and in Kenya the leaves and figs, have been recorded as famine food. [12] In South Africa a decoction of the bark mixed with cow feed is said to increase the flow of milk, [13] though the leaves have been shown to be toxic to cattle, and sometimes to sheep. [11] When ripe, the figs are readily eaten by several species of bird. [10] The pollinator wasp is Platyscapa soraria Wiebes., while Otitesella longicauda and O. rotunda are non-pollinators. [3]

Similar species

It is similar to the Wonderboom fig, which has a broadly overlapping range and occurs in comparable habitat. They differ with respect to leaf shape, venation and colour, besides the size and colour of the figs. The Wonderboom is always a tree, [4] and has elliptic-oblong leaves with a rounded bases, that are never bright red-brown. [8] Its figs are much smaller and mature to yellow-red. The Natal fig has the base of the leaf narrowly tapered. [4]

The inhabited tree
  1. Moffat relates it thus: "My attention was arrested by a beautiful and gigantic tree [a species of ficus], standing in a defile ... Seeing some individuals employed under its shade ... and houses in miniature protruding through its evergreen foliage, I proceeded thither, and found that the tree was inhabited by several families of Bakones, ... I ascended by the notched trunk, and found, to my amazement, no less than seventeen of these aerial abodes, and three others unfinished. On reaching the topmost [30 feet up], I entered, and sat down. I asked a woman who sat at the door permission to eat [a bowl full of locusts]. This she granted with pleasure, ... and soon brought me more ... Several more females came from the neighbouring roosts, stepping from branch to branch, to see the stranger, ... I then visited the different abodes, which were on several principal branches. ... A person can nearly stand upright in it: the diameter of the floor is about six feet [with] a little square space before the door." See: Moffat, Robert (1842). Missionary Labours and Scenes in Southern Africa. J. Snow. pp. 519–520: The inhabited tree.
  2. In the 1960s the tree was rediscovered by Eve Palmer at Boshoek north of Rustenburg. By the 1970s though, it had begun to collapse under its own weight. cf. Swart, W. J. (1984).

<i>Ficus</i> Genus of flowering plants in the mulberry family Moraceae

Ficus is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (F. carica) is a temperate species native to southwest Asia and the Mediterranean region, which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses.

Euclea crispa, commonly known as the blue guarri, is an Afrotropical plant species of the family Ebenaceae. The hardy and evergreen plants may form a dense stand of shrubs, or grow to tree size. It is widespread and common in the interior regions of southern Africa, and occurs northward to the tropics. Though some are present near the South African south and east coasts, they generally occur at middle to high altitudes. It is readily recognizable from its much-branched structure and dull bluish foliage colour. Those bearing lanceolate leaves may however resemble the Wild olive, another common species of the interior plateaus.

Wonderboom (tree) Dense grove of parent and daughter trees of the species Ficus salicifolia

The Wonderboom is a dense grove of parent and daughter trees of the species Ficus salicifolia, that descended from a central bole of about a thousand years old. It is situated in the Wonderboom Nature Reserve, Pretoria, and two circular walkways currently protect it from pedestrian traffic around its trunk and roots. As it has grown, its outlying branches have rooted themselves around the parent tree. This has repeated until there are now three layers of daughter trees encircling the mother fig, with 13 distinct trunks, covering an area with a diameter of over 50 metres.
