Gen. Char. Flowers (fig. 1.) regular, uniform, imperfectly 
separated ; the innermost barren or abortive. Calyx (see fig. 2.) 
of 5, acute, ascending, permanent teeth. Corolla (see fig. 1.) of 
5 nearly equal, inversely heart-shaped petals, with indexed points. 
Filaments (see fig. 1.) 5, hair-like, spreading beyond the petals. 
Anthers roundish. Germen (see fig. 1.) inferior, oblong, a little 
compressed at the sides. Styles 2, small, recurved, tumid and egg- 
oblong at the base ; at length somewhat enlarged, permanent. Fruit 
(fig. 3.) flat, with a broad thin border. Carpels with equidistant 
ribs ; the 3 middle ones slightly prominent, the 2 lateral more ob- 
solete, and contiguous to the dilated margin, or lost in it. Inter- 
stices ( channels ) (see fig. 4.) with from 1 to 2 vittce. Seed flat in 
front. Universal Involucrum various; partial one many-leaved. 
Flowers small, yellow or white. 
The 5-toothed calyx; the corolla of 5 nearly equal, inversely 
heart-shaped petals, with inflexed points ; the flat fruit , with a 
broad thin border ; the carpels with equidistant ribs ; the 3 middle 
ones slightly prominent, the 2 lateral ones more obsolete ; and the 
channels with from 1 to 2 vittce in each ; will distinguish this from 
other genera, in which the fruit is dorsally compressed and destitute 
of prickles, in the same class and order. 
Two species British.

hair-like. Flowers yellow.
