LXX. CORYLA‘CEE: O’STRYA. 919 
As it shoots out into numerous widely spreading, horizontal, irregular 
branches, it cannot be regularly trained up with a straight clear trunk. The 
leaves are much smaller than those of the common hornbeam, and the branches 
grow closer together ; so that it is even still better adapted for forming a 
clipped hedge than that species. Very hardy, and easily propagated by layers. 
Species or Varieties of .Carpinus not yet introduced into European Gardens. 
Carpinus (B.) Carpinizza Host, Fl. Aust. 2. p. 626, — Leaves crenately ser- 
rated ; scales of the strobiles revolute, 3-cleft ; the middle segment the longest, 
and quite entire. A native of the ‘ 
woods of Transylvania. The Tran- 
sylvanians distinguish this sort from 
C. Bétulus, and call it Carpinizza. 
C. viminea Lindl., Wall. Pl. As. 
Rar. t.106., Royle Illust. p. 341., 
and our fig. 1716., has the leaves 
ovate-lanceolate, much acumi- 
nated, doubly serrated} petioles 
and branchlets glabrous ; bracteas 
fruit-bearing, ovate-oblong, lacini- 
ate at the base, somewhat entire 
at the apex, bluntish. (Lindi. in 
Wall.) A native of the mountains 
of Nepal, in Sirmore and Kamaon ; 
and, according to Royle, on Mus- 
souree, at the height of 6500 ft. 
above the Ievel of the sea; flower- Y 
ing and fruiting from January to Vie. Ge yuminen: 
April. A fine tree, very like the common alder. ; 
C. faginea Lindl., Wall. Pl. As. Rar. 2. p. 5., has the leaves ovate-oblong, 
acute, sharply serrated, and glabrous ; petioles and branchlets downy ; bracteas 
fruit-bearing, somewhat rhomboid, with large teeth, acute, reticulated. It is 
nearly allied to C. orientalis, but ditfers in the form and margin of the leaf, 
and in the bracteas. (Wall. Pl. As. Rar., 2. p. 5.):
