GENERA. 



1. Vismia Yanbell. — Flowers hermaphrodite regular ; receptacle 

 convex. Sepals 5, thick subcoriaceous, abruptly attenuate at margin, 

 shortly imbricate. Petals 5, alternate, oftener villose above, twisted 

 in prefloration. Stamens oo , in 5 bundles, superposed to petals ; 

 filaments free at apex ; anthers short introrse, afterwards reflexed 

 and retrorse, longitudinally 2-rimose. Scales 5, hypogynous, alter- 

 nipetalous. Germen free, 5-locular ; cells complete or incomplete 

 alternipetalous ; style branches 5, distinct from base, at apex capi- 

 tellate stigmatose. Ovules in cells oo , inserted in internal angle, 

 anatropous. Fruit baccate, indehiscent. Seeds co , ascending or 

 subhorizontal, inserted on placenta with lobes often spongy, subcy- 

 lindrical ; cotyledons of straight or more rarely incurved exalbumi- 

 nous embryo plane or semiterete ; radicle short. — Trees or shrubs ; 

 with yellow or red juice ; leaves opposite exstipulate, entire, glabrous 

 or tomentose beneath, penninerved glandular punctate ; flowers in 

 terminal more or less compound racemose cymes. (Trop. America, 

 trop, west. Africa.) — See p. 382. 



2. Haronga Dup.-Th. — Flowers nearly of Vismia, hermaphro- 

 dite, 6-merous; ovules in each cell (complete or incomplete) few (2, 

 3), ascending ; micropyle extrorsely inferior. Fruit drupaceous 

 (small) globose ; pyrenes 5, 1-2-spermous. Seeds terete; cotyledons 

 of exalbuminous embryo plane elongate; radicle shorter. — A shrub; 

 leaves entire and other characters of Vismia ; flowers (small) 

 crowded in a terminal very racemose-decompound raceme. {Trop. 

 Africa, Madagascar.) — See p. 384. 



3 ? Psorospermum Space. ^ — Flowers nearly of Vismia ; ovules 

 in each cell (complete or incomplete) 1, 2, ascending; micropyle
