Lin. sysr. Pentandria, Digýnia. Margin of calyx obsolete. 
Petals obovate, entire, flat or attenuately inflexed at the apex. 
Fruit ovate or oblong ; mericarps with 5 exserted nearly equal 
winged ribs ; vittæ 2 in the commissure, which is flat, and one 
in each furrow. Seed with a furrow in front, convex on the 
outside. Carpophore bipartite.—Perennial glabrous herbs, na- 
tives of the mountains of Nipaul. Leaves decompound. Umbels 
terminal, of many rays. Involucra and involucels of many leaves, 
which are membranous, and are usually toothed or cut. This 
genus is allied to Molopospérmum on the one hand, and Pleuro- 
spermum on the other ; it differs from the first in the commissure 
being flat, in the ribs being equally winged, and in there being 
no empty canal before the commissure, &c.; and from the last 
in the fruit having the membranes joined together, and from 
both in the obsolete margin of the calyx. Perhaps this genus 
should be divided into two, from the oblong or ovate fruit of the 
species, and from the seeds being angular or convex on the 
outer side ; but in most of the species the fruit is not sufficiently 
known.
