42 ILLUSTRATIONS OF INDIAN BOTANY. 
all agree in their sarmentose habit and cordate leaves, but the form of the leaves differ, for 
sometimes they are broadly reniform cordate at the base, and obtuse at the apex ; others are. 
simply cordate, with a tendency to accumination at the apex, while in others they are distinctly 
accuminated and very sharp pointed: some s ecimens have acutely serrated leaves, others 
crenated, while in others again they are almost entire on the margine. The series of specimens 
upon which these observations are made were derived from the Neilgherries, Pulney mountains, 
Shevaroy hills, Shevagherry hills, and Ceylon, to which I may add, that Mr. Royle’s figure of 
the Himalayan form, perfectly corresponds with my native specimens derived from the above 
localities. The following characters will, I hope, sufficiently distinguish the new species from 
V.. Patrinii. 
Viola Walkerti. (R. W.) Stemless, leaves oblong, Viola Patrinii (D. C.) Stemless, leaves truncated 
cordate at the base, crenate, petiols short, wingless: atthe base, from oblong, to nearly triangular, some- 
peduncles much longer than the leaves, stigma mar- times longer (but usually much shorier) than the 
ined. petiol, petiols winged. : ; 
igherries, &c. The peduncles being either 
longer or shorter than the leaves, I have not referred to 
them in the character,

whom I first received Specimens, and from one of 
which the accompanying figure was taken.
