The Sphaerosepalaceae are a family of plants in the order of the Mallow-like (Malvales). This family contains only two genera with 14 to 20 species. The species have their areas only in Madagascar .
description
They are deciduous trees or shrubs . The alternately arranged leaves are simple with a smooth leaf edge. The mostly very broad stipules sometimes surround the branch.
The flowers stand in axillary or terminal zymous inflorescences together with bracts . The hermaphrodite flowers are radially symmetrical to weakly zygomorphic with a double perianth . There are two circles with two to three free, leathery sepals each, the inner ones are larger; all sepals clearly overlap. There are usually four (three to eight) free, nailed petals ; they are white or yellow. There is a ring-shaped disc. The 25 to more than 100 fertile stamens are clearly unequal; they are arranged in two to four circles, freely one below the other or grouped into two to four bundles; they are not fused with the petals. The upper permanent usually three (two to five) or sometimes under semi-permanent carpels are at Dialyceras partially exposed and Rhopalocarpus to an ovary grown. In both genera there is only one stylus.
Rhopalocarpus form split fruits that contain four to ten seeds. The two to five, usually three, one to two-seeded, capsule-like fruits of Dialyceras form a collective fruit. The large seeds are oily.
