The flowers are mostly sessile and rae, clustered, form- 
ing globose heads in the axils of sin bracts without 
bracts in the inflorescence. The central domate open ; 
the exterior ones are occasionally in C. Epithymum 
has sometimes short pedicels, and C. lonica is always 
pedicelled. The corolla always remains on ton or around the 
capsule, never at its base. Epistamineal scales are always pre- 
sent, though sometimes very thin and small, and easily over- 
oked. 
The species of this group inhabit Europe, western and cen- 
tral Asia, and northern Africa to the Canary Islands.

It is certainly difficult to make precise the lite of C. Epi- 
thymum and C. planifiora, and some forms which I class un 
a var. Kotschy of the former, and others which fall under 
imata of the latter, apparently are more closely al- 
lied than the extremes of either species among themselves ; 
while the common C. Epithymum, especially the form known 
as C. T'rifolti, is as distinct as can be from Tenore’s original
