Gen. Plant. i. 887. 
Calyx-teeth conspicuous, acute. Petals entire, ovate, with a long 
involute acumen, somewhat imbricate in estivation. Disk with undu- 
lated margin and conical stylopods. Fruit smooth, obovate-oblong, 
laterally compressed to rather a wide commissure; primary ridges 5 in 
each mericarp, unequal, 2 of which in 1 mericarp and 3 in its fellow 
are winged ; the 2 lateral wings in the latter either patent or appressed 
to the adjacent sides of the former, thus making the fruit 5- or 3- 
winged ; 1 mericarp often abortive. Vitte 12, conspicuous, alternate 
with the ridges, and 2 in each commissural face. Carpophore bi- 
partite. Seeds subterete—A glabrous shrub with slender terete rubes- 
cent branches. Leaves flat, of a pale bright green colour, simple or 
3—5-foliate, thinly coriaceous, minutely reticulate; leaflets lanceolate, 
acute or occasionally blunt, narrowed at the base, simple or bifoliate, 
terminal one often trifoliate ; petioles amplexicaul at the base. Umbels 
regularly compound, terminal and subterminal, of many rays; invo- 
lucre of many unequal fugacious leaflike simple bracts; involucels of 
many small lanceolate bracteoles.
