306 PENTANDRIA— MONOGYNIA. Viola. 



short, blunt, yellowish spur. Calyx-leaves lanceolate, pointed. 

 Capsule shorter and rounder than in canina. 

 This little plant, long ago communicated by the late Mr. Crowe, 

 is not uncommon, though usually neglected as a variety of the 

 V. canina. It lias remained unchanged, and of the same hum- 

 ble stature, perfectly shrubby, for above 12 years, in a common 

 garden ; and seems entitled to rank as a species, under the 

 svnonym of Dillenius, though his figure by no means repre- 

 sents the true nature of the stem, nor does it exhibit any of the 

 parts most material for specific discrimination. I have al- 

 ready adverted to this Violet in Rees's Cyclopaedia under the 

 canina, n. 26.

 equally dilated. Petals very variable in size and colour, gene-
