bution. In European Russia found in the province of Astrakhan, 
on hills near the Volga above Tzaritzyn and Astrakhan; and nr. 
Slatoust, in the province of Ufa (the ores limit of the species). 
In Asiatic Russia it is recorded from the Western Caucasus at 
Dariaia, Beret Lake Baikal, In Asiatic Turkey it occurs at 
Djimil, in the vilayet of Trebizond, at about 2000 metres (Balansa) ; 
and in N, Persia on Mt, Elbruz (Buhse). In the Himalayas the 
Grade is recorded from Gilgit, in Dardistan (Dr. Giles, 1887), 
eastward to Kumaon (Strachey), the latter specimens marking the 
south limit of the species. an “y Damdar vey: in Garhwal,

(C. Mesiacum Friw.). According to Borbas, this oul be kent up 
as a gg of which C, Mesiacum should be considered a local 
form. m the series of specimens I examined in Herb. Ziirich, 
I do not think the characters are sufficiently distinct to separate it 
specifically from C. tomentosum. These specimens are distinguished 
from the normal forms of C. tomentosum by the following cha- 
racters :—Indum hag minus canum ; caulis erectus crassior haud 
vel vix ramosus ; “folia inferiora late elliptica (20 x 17 mm.), media 
lanceolato-oblonga (20 x 11 mm.); dichasium pluriflorum ; sepala 
lus scariosa; petala longiora semper calyce duplo longiora.
