Morphology General Habit
Monoecious or rarely dioecious perennial herbs (or, outside Somalia, shrubs), often with fleshy or succulent stems, or stemless, with rhizome or subterranean tuber, milky latex usually present
Morphology Leaves
Leaves alternate, in stemless species arising ± directly from the subterranean tuber, petiolate, entire or with a crenulate, crenate, dentate or irregularly toothed or lobed margin
Morphology Leaves Stipules
Stipules lateral, free, caducous or persisting
Morphology Reproductive morphology Inflorescences
Inflorescences single or up to 5 together in the leaf axils, pedunculate, peltate, circular or elongated, with flowers on the upper side, a thinner flowerless margin and mostly with long marginal appendages Flowers densely crowded on or deeply embedded in the upper surface of the receptacles
Morphology Reproductive morphology Flowers
Male flowers often more numerous than the female ones, only partially embedded, with 2–3-lobed perianth and 1–3 stamens, which are inflexed in bud; rudimentary ovary present or absent Female flowers deeply embedded, perianth without clearly defined lobes and mostly with a ± constricted opening through which the style protrudes; ovary completely enclosed, with an obliquely placed terminal or lateral style; stigmatic branches 1 or 2
Morphology Reproductive morphology Fruits
Fruit subglobose to ovoid, with a fleshy exocarp and a hard, smooth or rugose endocarp, which at maturity is ejected by the elastic exocarp.
Distribution
About 120 species, widespread in tropical America and Africa, also on Madagascar, Socotra, in Arabia, and one species in India.

Moraceae, C. C. Berg. Flora Zambesiaca 9:6. 1991

Morphology General Habit
Herbs, often at least somewhat succulent, rhizomatous or tuberous, or shrubs.
Morphology Leaves
Leaves spirally or distichously arranged, pinnately veined, less often palmately or radiately veined; stipules lateral, free.
Morphology Reproductive morphology Inflorescences
Inflorescences bisexual, borne in the leaf axils, discoid to turbinate, or naviculate, circular, elliptic or stellate in outline, receptacle mostly with marginal and/or submarginal appendages, sometimes also bracteate outside; flowers connate.
Morphology Reproductive morphology Flowers
Pistillate flowers (in the central part of the inflorescence) 1-numerous; perianth tubular with only the apex free from the surrounding flowers; ovary free; stigmas 2, filiform to ligulate, equal or unequal in length, or 1. Staminate flowers numerous; tepals (1)2–3(4), free or basally connate; stamens 2–3; pistillode usually absent.
Morphology Reproductive morphology Fruits
Fruit a dehiscent drupe; the white fleshy part pushing out the endocarp body (pyrene) if large, or ejecting the endocarp body if small; endocarp body (especially if large) subglobose and smooth or tetrahedral and tuberculate.
Morphology Reproductive morphology Seeds
Seed large and without endosperm, or small and with endosperm; cotyledons thick and unequal or flat and equal.
