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- 

 scars alternate, somewhat raised, 

 half-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. T. Regelii.
