median band outside, and in having less deeply cut leaflets. 
It is not, however, at all certain that the Chinese var. 
rubens, Hort., is the same as the original var. rubens, 
Kuntze, which is based on a statement by Hooker and 
Thomson that in the Himalaya the flowers of C. montana 
are sometimes pinkish. Like other members of the genus, 
C. montana, var. Wilsonii thrives in a rich loamy soil which 
is all the better if of a calcareous nature. At Kew, where 
no lime is actually present in the soil it is found very 
advantageous to many species of Clematis if slaked lime 
be added. Like the other varieties of C. montana, our 
plant produces its flowers from the nodes of the previous 
season’s growth; it should therefore only be pruned after 
the flowers are past, and the shortening back of the shoots 
during winter, so useful in the case of most species of 
Clematis, must here be avoided. Propagation can be 
readily effected by means of cuttings. The garden value 
of this variety is enhanced by the fact that it flowers at 
least two months later than the typical C. montana and 
about six weeks later than var. rubens. 
Description.—Shrub, climbing ; stems striate puberulous. 
Leaves opposite, 3-foliolate; petioles 14-4 in. long, finely 
sparingly puberulous; stalks of the end leaflet 2—1 in. long, 
twice or thrice as long as those of the lateral leaflets ; 
leaflets ovate narrowly acuminate, truncate or subcordate, 
those of the flowering shoots elliptic and narrowed to the 
base, 14-3 in. long, 1-1$ in. wide, wide serrate with 
apiculate teeth; thin, glabrous above, puberulous on the 
nerves beneath; nerves sunk above, raised beneath. 
Flowers fascicled on short leafy branchlets clothed with 
bud-seales at the base. Peduneles 1-flowered, slender, 
6-8. in. long, puberulous. Sepals 4, petaloid, white, 
induplicate-valvate, obovate-oblong, retuse but mucronulate 
at the tip, 3-1 in. long, about 3 in. wide, glabrous within, 
almost so along a central band outside, but densely pubes- 
cent elsewhere. Petals 0. Stamens.many, the outer 2 in. 
long, the inner under 3 in. long; filaments linear, glabrous ; 
anthers linear or narrow oblong, 1-14 lin. long; dehiscence 
lateral. Carpels many; ovary compressed, glabrous; style 
glabrous above, silky hairy elsewhere.
