200 CELASTRACEAE. 
TRIPTERYGIUM. 
(Family Celastraceae). 
Snrubs: deciduous. Twigs 
moderate, angled, very warty, 
somewhat zig-zag: pith round, 
continuous, with firmer cross- 
plates at intervals, pale, pink- 
ish. Buds moderate, solitary, ses- 
sile, conical, nearly horizontal, 
with about 2 exposed scales. Leaf- 
sears alternate, somewhat raised, 
haif-round: bundle-trace 1, C- 
shaped: stipule-scars lacking. 
Few shrubs are so well marked 
by conspicuous winter-characters 
as this newly introduced Asiatic 
species, and Mrs. Vieh has brought 
these out unmistakably in a few 
strong lines in the accompany- 
ing sketch which may be taken 
as a model of such illustration. 
The rusty coloration of the twigs 
is quite as characteristic as the 
clean-cut buds, leaf-scars, and surface. 
Twigs rust-colored, glabrous. - TT. Regelii.
