pearing with the leaves at the base of the young branchlets ; 
bracts linear, slightly exceeding the calyx; bractlets none; 
ovaries connate about two-thirds, 2-celled; calyx cupulate, 
short, indistinctly 5-lobed; corolla tubular-funnelform, 
about 10 mm. long, apparently yellowish, distinctly gib- 
bous at the base, limb with 5 orbicular-ovate lobes 1.5-2 
mm. long; stamens as long as or slightly exceeding the

This species resembles in its habit very much ZL. 
obovata, L. microphylla and L. Szechuanica; from the 
first it is distinguished by the absence of the bractlets, 
from the second by the subequal limb and from the third 
species as well as from L. serpyllifolia and L. Tangutica 
by the gibbous corolla; from the following species with 
which it shares the gibbous corolla it is easily distinguished 
by the shape of the nearly glabrous leaves and the short 
peduncles.
