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, pl. 8).
