434 NATURAL HISTORY OF PLANTS. 



placed half-a-dozen closely allied genera, also tropical American ; 

 Byrsonima, trees or shrubs, often climbing, whose drupaceous fruit 

 has a trilocular core, and whose stamens are hairy below, whilst the 

 styline branches are pointed ; Bunchosia, whose stamens are com- 

 pletely glabrous, and whose styline branches, obtuse or truncate at 

 the apex, are, consequently, like those of MalpigMa^ but united to- 

 gether to a variable extent, and also distinguished by drupes with 

 two or three kernels destitute of dorsal projections and ridges ; 

 Glanchnia, whose flower is that of Byrsonima, but whose staminal 

 filaments are glabrous, and the fruit a unilocular and monospermous 

 nut ; Diacidia, also having the flowers of Byrsonima^ with ten glands 

 to the calyx, anthers whose cells are each surmounted by a small 

 tuft of hairs, pointed styline branches, two or three in number, and 

 a nucular li-uit, with two or three cells ; Dicella, with nucular uni- 

 locular fruit, whose two styline branches are truncate at the apex, 

 and the stamens nearly always bristling with hairs. Moreover, the 

 petals are unequal and unlike ; making this genus, in this small 

 group, analogous to Vcvrucularia among the Spachcce ; and the calyx 

 is accrescent after efilorescence. In Biirdachia^ the dissimilar petals 

 of Dicella are observed, and the dry unUocuJar fruit, often conical, 

 has projecting vertical ribs ; but the calyx is not accrescent ; the 

 glabrous staminal filaments rest on a glandular annular disk, and the 

 styline divisions are pointed and subulate, instead of appearing trun- 

 cate at the apex. 



II. BANISTEEIA SEEIES. 



The flowers of Banisteria} are constructed very nearly the same as 

 in Malpifjhia^ with a calyx bearing eight or ten glands, more rarely 

 without glands ; five equal or unequal petals ; ten stamens arranged 

 in two verticels ; anthers inappendiculate, or provided with a dorsal 

 projection of the connective ; an ovary with thi-ee uniovulate cells,
