Key to the Species. 
1. All the leaves distinct, flowers in pairs on axillary peduncles. 2. 
1. Upper leaves connate-perfoliate, flowers in heads or interrupted spikes .6 
2. Shrubs, not twining; cluster small with small, linear to subulate bracts; 
flowers small, f to f inch long. 3. 
2. Twining vines; flowers large, lj to If inches long, white or pink fading 
to yellow. L. japonica. 
3. Corolla almost actinomorphic; twigs glabrous; leaves green on both 
sides. 4. 
3. Corolla zygomorphic, more or less 2-lipped; twigs pubescent when young, 
sometimes becoming glabrous when mature; leaves pale green, lighter 
beneath than above. 5. 
4. Leaves not ciliate; bracts linear; corolla with wide spreading lobes about 
as long as the tube, white to rose colored. L. tarlarica. 
4. Leaves strongly ciliate; bracts small subulate; corolla lobes shorter 
than the tube, greenish yellow. L. canadensis. 
5. Leaves glabrous or nearly so when mature, not ciliate; peduncles l to lj 
inches long, slender. L. oblongifolia. 
5. Leaves persistantly pubescent beneath, ciliate; peduncles j to 5 inch 
long. L. xylosteum. 
G. Corolla tubular, nearly regular, glabrous; leaves dark green above, 
slightly glaucous beneath; stamens and style little exserted.

8 . Leaves pubescent on both sides, very strongly so beneath, only slightly 
glaucous. L. hirsuta. 
8 . Leaves glabrous on both sides or only slightly pubescent beneath; very 
glaucous. 9.
