INDIAN SPECIES OF PRIMULA AND ANDROSACE. 8 
faet is the existence of two great centres of concentration of 
species, namely the mountains of Central Europe and of North 
India; and although some of the species of the two regions over- 
lap in the intervening country, two only seem to be common to 
both regions. Of the Himalayan species, the only one besides 
P. farinosa that has a wide range outside of India is P. sibirica*. 
This inhabits Central and Northern Asia and Arctic America 
from Kamtschatka to Greenland. Most of the species of this 
region are endemic, and some of them apparently local, whilst 
others extend from Sikkim to the north-west, and are so variable 
that they are difficult to define. A large number of forms have 
been referred to P. denticulata, P. Stuartii, and P. petiolaris, 
whether rightly or wrongly could not be determined. On the 
other hand, some forms have been raised to the rank of species, 
because with our present materia] they are readily distinguished. 
Whatever rank we assign them, the numerous forms of Primula 
constitute one of the most charming and characteristic features 
of the alpine vegetation of Northern India. 
1. Primura, L. 
A. Leaves on long slender unwinged petioles, orbicular oblong 
or cordate, margins revolute in vernation. (See also 
P. tibetica.) 
1. P. Gampetiana, Watt; gemmis farinosis, foliis 1-1 poll. 
diam., orbiculari-cordatis dentatis, umbellis paucifloris, bracteis 
1-3 subulatis, corolla purpurea, ore obscure annulato, lobis orbi- 
cularibus emarginatis. (Tas. I.) 
SIKKIM HIMALAYA: Jongri, alt. 14,000 ft., G. Watt. 
Allied to P. rotundifolia, but much smaller, with fewer and 
larger flowers. Leaves membranous, resembling those of P. 
pulchra, but not sheathed with large fleshy scales at the base. 
Scape and inflorescence quite glabrous. ^ Corolla-limb concave, 
1-1} inch diam. Ovary and stigma as in P. rotundifolia. Fruit 
unknown. 
Prats I. fig. 1, whole plant, nat. size. 2, calyx; 3, corolla laid 
open; 4, ovary: all enlarged. 
2. P. PULCHRA, Watt; glaberrima, efarinosa, caule vaginis 
* Sir J. Hooker informs me that he is convinced that a revision of the genus 
will result in the identification of several of the Western Himalayan species with 
‘North Asiatic and even European ones.
