A group of 28 species distributed from Japan, Korea 
and China west to the Himalayas and south to the Malayan 
Archipelago; by one species it is also represented in south- 
western Europe and in northern Africa. It forms a transi- 
tion to the subgenus Periclymenum by its habit and the 
shape of its corolla, but its closest relation is certainly 
with the subgenus Chamaecerasus where it is placed by De 
Candolle and Koehne, while Spach, Maximowicz and 
Clarke refer it to Periclymenum. By Dippel and Fritsch 
it is considered a separate subgenus. Twining shrubs, 
rarely creeping; the branches with evanescent, rarely per- 
sistent pith; leaves deciduous or evergreen; flowers in 
axillary pairs, often crowded toward the end of the 
branches and forming terminal panicles; bracts subulate, 
rarely leafy; bractlets and ovaries distinct, except in 
L. calearata; ovaries 3-, rarely 4- or 5-celled; corolla 
two-lipped, 1.5-16 cm. long, with long and slender or 
shorter and sometimes slightly ventricose tube, only in 
a x. oo ea
