HAMAMELIDACEAE. 



89 



CORYLOPSIS. 



(Family Hamamelidaceae). 



Shrubs : deciduous. Twigs 

 rounded, zig-zag, moderate or 

 slender, mostly glabrescent: 

 pith rather small, somewhat angu- 

 lar, continuous. Buds rather 

 large, sessile and solitary or 

 finally short-stalked and collater- 

 ally branched, directly in the axil, 

 fusiform or ovoid, with about 3 

 glabrous scales, the end-bud some- 

 what larger. Leaf-scars alternate, 

 2-ranked, half-round or 3-sided, 

 slightly raised, small: bundle- 

 traces 3: stipule-scars equal, elon- 

 gated. 



Fothergilla, Hamamelis and 

 Parrotia possess a marked general 

 resemblance in bud and twig 

 characters; and their woody 

 fruits, which require a year for 

 maturing, are much alike. Neither 

 Liquidambar nor Corylopsis bears the slightest resemblance 

 to them in these respects, so far as general appearance is con- 

 cerned. Winter-characters of Corylopsis have been studied 

 by Schneider (C. spicata, f. 96) ; and Shirasawa (C. pauci- 

 flora and C. spicata, 262, pi. 8).
