Gen. Char. Calyx (fig. 1.) inferior, of 4 upright, egg-oblong, 

 blunt, deciduous sepals, equal at the base, approaching towards the 

 top. Corolla cruciform (forming a cross) , of 4 inversely' egg-shaped, 

 blunt, horizontal petals (fig. 2.), with upright claws shorter than 

 the calyx. Filaments (fig. 3.) 6, awl-shaped, simple, distinct, as 

 long as the calyx, two of them shorter than the other four. Anthers 

 (see fig. 3.) arrow-shaped, upright. Germen (fig. 4.) oblong. Style 

 short and thick. Stigma blunt. Pod ( siliqua ) (fig. 5.) sessile, 

 spear-shaped, compressed laterally, tapering upwards ; valves flat, 

 without ribs, narrower than the partition, bursting elastically from 

 the base, and mostly revolute (see fig. 6). Seeds (see fig. 6.) egg- 

 shaped, not bordered, disposed alternately in a single row ; their 

 umbilical cord broad. Cotyledons accumbent (o=), rather thick 

 (see fig. 7). 



The lanceolate (spear-shaped) pod ; flat, nerveless valves, nar- 

 rower than the partition, and usually separating elastically from 

 the base; arid the seeds with a broad umbilical cord; will dis- 

 tinguish this from other genera with accumbent cotyledons, in the 

 same class and order. 



One species British. 



DENTA'RIA BULBFFERA. Bulbiferous Toothwort. Coral- 

 root. Toothed Violet. 



Spec. Char. Stem-leaves alternate, lower ones pinnated ; up- 

 per simple, with axillary bulbs.

* From dens, a tooth ; from the tooth-like scales of the loot; for the same 



reason it is called toothwort in English.
