This group contains 13 species of which one is native to 
North America, one to Europe, one to north Africa and 
one to western Asia, while all the others are from central 
and eastern Asia. They are closely related to the preced- 
ing group, but chiefly distinguished by the elongated, 4- 
angled winter buds with persistent acuminate scales, by 
the usually conspicuous acute calyx teeth, the granulose 
seeds, the absence of glandular pubescence on the foliage, 
their less robust habit and generally much smaller leaves. 
Medium-sized, rarely large, upright shrubs with the slender 
branches glabrous or nearly so; leaves usually glabrous or 
only slightly pubescent, never glandular, usually rather 
small; flowers appearing on the middle and upper part of 
the branches on slender, long or sometimes short 
peduncles; bracts small, subulate; bractlets connate 
into a cupula or in pairs; calyx teeth conspicuous, 
acute, obsolete only in L. conjugialis; corolla two-lipped, 
about 1 cm. or less long, yellowish-white to pinkish or 
violet purple; tube short and gibbous; style pubescent,
