Names
Psorospermum Spach [family GUTTIFERAE], in Ann. Sci. Nat., Bot., Sér. 2, 5: 157 (1836).
Information
Trees, shrubs or shrublets. Leaves opposite, less frequently subopposite or alternate, petiolate, entire, often furnished with opaque glandular dots and stellate indumentum. Inflorescence a terminal panicle, usually cymose. Flowers bisexual. Sepals 5, with longitudinal linear glands. Petals 5, villous within, furnished with longitudinal glandular lines and swollen nectariferous tissue at the base. Androecium of 5 fascicles of stamens, with few to many stamens in each fascicle and filaments united for most of their length; fasciclodes 5, fleshy, scale-like, alternating with the fascicles. Ovary 5-locular, with 1 (2)-ovulate loculi and ascending ovules; styles 5, free. Fruit a berry. Seeds large, with a fleshy glandular-punctate testa.
Notes
Note. In P. chevalieri Hochr., from Upper Oubangui, all floral parts vary from 5 to 6.This genus differs from Vismia Vand. in having usually one ovule per loculus instead of many and seeds with a fleshy testa. Apart from continental Africa it occurs only in Madagascar, where it is represented by 21 endemic species. No species of Vismia is known from our region, but V. orientalis Engl. may be present in northern Mozambique.
