to be a subterranean creeping stem as in V.palusiris, but our specimens 



scarcely show a greater difference in that respect between this and 



the last species, than may be caused by the soil: the length of the 



anther-spurs is dependent on that of the spur of the coroUa. A small 



plant in the wild state, sometimes a foot high when cultivated, having 



usually several flowering simple branches fiom near the root ; these 



seem scarcely so persistent as in the last species, from which it may 



not be really distinct. Leaves almost lanceolate and narrower, usually 



attenuated at the base, but sometimes cordate. Stipules usually 



much shorter than the petiole. Stigma very slightly curved, almost 



clavate and quite smooth, without any horizontal beak, the orifice 



oblique and very large. Flowers pale blue or almost white. 



if Stigma large, capitate, style clavate. 



7. V. tricolor L. {Pansy V. or Hearts Ease) ; root annual 

 or fusiform, stem angled branched, leaves oblong deeply crenate, 

 stipules lyrate-pinnatifid, terminal lobe crenate, spur of the 

 corolla about as long as the produced base of the calyx, "anther- 

 cells diverging at the base/' — a. petals longer than the calyx.

 variable, especially in the size and colour of its flowers, yellow in 

 r. Curtisii of Forster, which we certainly consider belongs to this 

 and not to V. lutea. Stigma, in this and the following species, large, 

 capitate, obliquely perforated. 



8. V. lutea Huds. (yellow Mountain F., or yellow Pansy) ; 

 perennial diffuse and filiform below -ground, stem branched and 

 very slender at the base, leaves oblong-ovate or ovate crenate, 

 stipules subpalmato-pinnatifid, terminal lobe entire, spur of the

Mountainous pastures. Frequent in Wales, the north of England 

 and Scotland; a and )8 often growing together. %. 5—9. — Under- 

 ground stems or branches resembling long thread-like roots; true stems 

 also slender but particularly so at the base ; both very different from 

 what we have always seen in F. tricolor, and by which this species is 

 in some cases only to be distinguished. The flowers are generally of a 

 pale yellow or sulphur colour, much larger than is usual in wild states 

 of V, tricolor.
