This subgenus contains about 22 species distributed 
from the Mediterranean region to North Europe, Afghan- 
istan, Central China and in North America from Canada 
to Mexico. They are twining or rarely dumose shrubs 
with hollow branches and deciduous or persistent leaves of 
which one or several pairs below the inflorescence are often 
connate into a disk. Flowers at the end of the branches 
in sessile three-flowered cymes, rarely reduced to one flower, 
in the axils of bract-like leaves or of leaves connate into a 
disk, the whorls forming terminal spikes or heads; bracts 
small; bractlets distinct except in L. Griffithii, sometimes 
wanting; ovaries always separate, 3-celled; calyx often 
obsolete, never very conspicuous; corolla two-lipped or 
sometimes with short almost equal lobes, tube long and 
slender or short and sometimes gibbous; style glabrous or 
pilose; fruit red and fleshy with yellowish-white smooth 
seeds. 
A. Corolla with short almost equal limb or indistinctly two-lipped and 
the lower limb slightly spreading, tube more or less ventricose 
below the middle or somewhat gibbous, hairy within; stamens 
inserted below the base of the limb; upper pair of leaves always 
connate. 21. Subsect, PHENIANTHI. 
AA. Corolla deeply two-lipped with the lower lip reflexed or revolute; 
stamens inserted at the base of the limb, 
B. Bractlets distinct. 
C. Corolla 1.5-2.5, rarely 3.5 cm. long, yellow or yellowish- 
white, often tinged purple, tube usually ventricose below 
the middle or gibbous, pubescent within, about as long 
or rarely longer than limb; style pilose or sometimes 
glabrous. 22. Subsect. CyYPHEOLAE. 
CC. Corolla 4-8 cm. long, rarely shorter, usually white or yel- 
lowish-white; tube slender, gradually narrowed toward the 
base, longer than limb, glabrous within (except in L. im- 
a ; plexa and L. tragophylia); style glabrous (except in L. im- 
es eee eae plexa). 23. Subsect. EUCAPRIFOLIA.
