numerous.--Species 2. West Africa. They yield timber and edible fruits
(blood-plums). =Haematostaphis= Hook. fil.
Flowers 4-5-merous. 26
26. Flowers 4-merous. Fruit usually 1-seeded. 27
Flowers 5-merous. Fruit 2-5-seeded. Leaflets 5 or more. Sepals united

alternate.--Species 1. West Africa (Cameroons). =Nothospondias= Engl.
Sepals united at the base only. Petals obovate. Disc 8-crenate. Styles
3-4. Stone of the fruit with 1-2 fertile cells bearing a lid at the
top and with 2-3 sterile cells. Seeds 1 or 2; in the latter case
leaflets 3.--Species 30. Tropical and South Africa. Several species
yield timber, bark used for making cloth, gum, edible fruits, and
medicaments. (_Calesiam_ Adans., _Odina_ Roxb., including _Lanneoma_

28. Male flowers with a narrow disc and 3 styles. Stone of the
fruit with 2 fertile and 2 sterile cells.--Species 1. South Africa.
=Harpephyllum= Bernh.
Male flowers with a broad disc and 5 styles. Ovary 5-celled. Stone of
the fruit with 3-5 fertile cells. Panicles spike-like.--Species 5.

Shrubs or trees. Leaves alternate, entire toothed or lobed. Flowers
regular, dioecious. Calyx 4-7-cleft. Petals 4-7, united at the base,
imbricate in bud. Stamens as many as the petals, hypogynous. Anthers
2-celled, opening inwards by longitudinal slits. Disc none. Ovary
superior, 4-8-celled. Style short or absent; stigma lobed. Ovules
solitary in each cell or two side by side, pendulous, inverted,
covered by a cupular expansion of the funicle. Fruit a drupe with
4-8 one-seeded stones. Embryo minute, at the apex of the albumen
(_ILICINEAE._)
