Clematis montana, Buch., is a somewhat polymorphic 
species widely spread in the Himalaya and in the mountains 
of Western and Central China. Ten distinct varieties have 
been recognised by Briihl as occurring in Sikkim, Tibet 
and Yunnan, though some of these depart so markedly 
from typical C. montana that they might perhaps be just 
as well treated as distinct species. The variety which 
forms the subject of our plate is a native of China; our 
figure has been made from a plant which flowered in July, 
1909, in the Coombe Wood Nursery of Messrs. J. Veitch 
& Sons, where it is known as the “autumn flowering 
C. montana” ; it was obtained for them in Central China 
by their collector, Mr. E. H. Wilson, whose name it bears. 
It appears to be most nearly allied to a variety of 
C. montana from Hupeh with pink flowers. But in addition 
to having white in place of pink sepals, var. Wilsonii differs 
from the variety rubens of our gardens in having the 
sepals more oblong, with a more sharply marked glabrescent
