SYNOPSIS OF THE GENUS LONICERA. 173 
China: Szechuen (Henry, no. 8936); W. Szechuen and 
Tibet frontier (Pratt, no. 364); in herb. Kew. 
This is a very well marked species with no close affinity 
to any other. It is the only Old World species of the sub- 
section Phenianthi and from the other species easily dis- 
tinguished by the funnelform corolla, the high insertion 
of the short filaments and by the sessile whorl.

A group of ten species, all native to North America and 
distributed from Canada south to North Mexico, except one 
Chinese. Twining or sometimes bushy shrubs with decidu- 
ous or evergreen leaves, the uppermost pairs of the flower- 
ing branches usually connate into a disk; whorls of flowers 
forming spikes, rarely solitary; bractlets minute or half as 
long as ovaries; calyx small, often obsolete; corolla two- 
lipped, 1.5-3.5 cm. long, with the tube about as long as or 
little longer than limb, orange yellow to yellowish-white, 
sometimes tinged purple, tube gibbous or more or less ven- 
tricose, hairy within except in L. flava; style glabrous or 
pubescent. 
This group seems to be closer connected with the pre- 
ceding than with the following group, though ZL. flava in 
the shape of the corolla and its nearly glabrous inside ap- 
proaches the Eucaprifolia, but in general habit and its other 
characters it shows a close affinity to LZ. Sullivantii and 
other American species. |
