Information
Shrub or tree, sometimes a scrambler, 1-3 m high, 3-5 cm diam. Bark pale grey, brown or green on younger branches and dark grey on older branches. Leaves alternate, simple (rarely 2-3-foliolate), petiolate; lamina narrowly elliptic, elliptic or obovate, 5-12 cm long, 1 • 2-4 cm wide, apex acuminate, obtuse, rounded or emarginate, mucronate, base cuneate to broadly cuneate, midrib depressed above with scattered papillae, prominent below and white or cream lateral veins 5-10, fairly prominent below, reticulate, char-taceous, glabrous; petiole 3-5 mm long, often curved or at angle to blade, channelled, verrucose. Inflorescence of axillary 4-8 flowered racemes; pedicels 2-3 cm long, slender. Receptacle shortly cylindric, 1 • 5-3 mm long, 2-3 mm diam. at mouth, smooth or slightly ribbed; disc entire or sometimes scalloped with the concavities situated at the base of the sepals. Sepals 4, obovate-spathu-late, 4-6 mm long, 2-3-5 mm wide, apex acute or obtuse, apiculate, margin irregularly crenulate, occasionally entire. Petals 0. Androphore 1 -5-4-5 mm long, exserted up to 2 mm. Stamens 15-30,1-1 • 3 cm long; anthers c. 1 mm long. Gynophore 5-1-3 mm long. Ovary broadly ellipsoid-globose, 1 mm long, capitate; ovules 5. Fruits globose, 0-8-1-5 cm diam., smooth to faintly and minutely colliculate. Seeds 3-5, reniform, 3-5 mm long, crustaceous, smooth. Fig. 22 ; 10.
Habitat
A variable species as regards leaf shape and size, but clear-cut taxonomically with simple, chartaceous leaves with a conspicuous white-cream midrib and veins fairly prominent on both sides, small apetalous flowers and small, globose fruits about 1 cm in diameter. The plant has a large rootstock, about 35 cm long and 12 cm in diameter at the top, which, according to Sim (1907), is eaten by the Bantu when food is scarce. A note on a specimen in SAM (Pros­pect Farm; collector unknown) states that a sweet syrup not unlike "golden syrup" can be extracted from the fleshy roots and that a substitute for coffee is also made from the plant.
Use
8. Maerua racemulosa (A.DC.)Gilg & Ben. in Bot. Jahrb. 53 : 252 (1915). Type : "Africa australis", Masson s.n. (BM, holo.; PRE, photo.).
Range
A slender shrub, small tree or scrambler occur­ring chiefly in dune, coast and semi-coast forest. In open situations M. racemulosa tends to be more leafy and branched. Its distribution is from Wilderness in the Cape, northwards to Natal, Zululand and Swaziland. It has also been recorded in Lesotho.
