Subsect. 14. Alpigenae, subsect. nov. 
A group of 14 species distributed from eastern Asia in- 
cluding Japan through central Asia to Europe. It is 
closely allied to the following subsection, but differs in the 
thick, ovate winter buds with obtusish, more or less cadu- 
cous scales, the often glandular pubescence, the short 
obtuse or obsolete calyx lobes and the large nearly smooth 
seeds. Besides these distinctive characters there are other 
peculiarities inthe general habit of the species of the two 
subsections, difficult to describe, but easily recognized if 
one is familiar with some of the species ; by these char- 
acters taken together the two groups appear well marked, 
though the differences may seem rather slight. The 
Alpigenae are medium-sized or large upright shrubs with 
rather stout branches; leaves large for the genus, glabrous 
or pubescent; flowers appearing on the lower part of the 
branchlets on long peduncles usually thickened toward the 
apex; bracts usually subulate; bractlets small, in pairs or 
connate into a cupula; calyx with short obtuse or obsolete 
teeth; corolla two-lipped, dull-colored, generally about
