Clematis orientalis is the most widely distributed of the 
known species of the genus, extending from the Cyclades 
and Caucasus Mts., eastward through North Persia to 
Affghanistan, and in the Western Himalaya as far as the 
confines of Nepal; and from Soongaria and the Pamir to 
the Altai Mountains, Manchuria, and North China. It 
varies greatly in the size of the flowers ; and so much in 
the form of the sepals, that I suspect the Himalayan 
O. graveolens, Lindl. (tab. nostr. 4495), which is said to be 
a aren by its fetid odour, will prove to be a variety 
of it. 
Living plants of var. tangutica were received by the 
Royal Gardens, Kew, from the Imperial Gardens of St. 
Petersburg in 1898, which flowered in the Arboretum in 
August, 1899.
