The striking form of Clematis uncinata which is the 
subject of our plate differs from the plant originally 
described as C. wncinata by Champion, by its leafy 
inflorescence, that of the type being comparatively 
leafless, and by its leaflets being all retuse in place of 
acutely acuminate and recurved or almost hooked at 
the tip, the feature to which the species owes its name. 
Yet in spite of the distinctive appearance thus imparted 
to the present form, the two extremes are connected by 
a series of intermediate conditions, the existence of 
which renders it impossible to accord our plant even 
the rank of a variety. For the material from which our 
illustration has been prepared we are indebted to Captain 
D. V. Pirie, in whose garden at the Chateau de Varennes, 
a few miles west of Angers, it makes a most beautiful 
picture, clambering over a wall and succeeding under the 
strong sun of Western France much better than it does 
at Kew. Fragrant as well as graceful, C. uncinata is 
evidently a species which loves bright sunshine. In 
OcroBER, 1915.
