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 Cdrpinus not yet introduced into European Gardens. 



Cdrpinus (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. #etulus, and call it Carpinizza. 



C. viminea Lindl., Wall. PI. As. 

 Rar. t. 106., Royle Illust. p. 341., 

 and our Jig. 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. (Lindl. 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 level of the sea ; flower- 

 ing and fruiting from January to 

 April. A fine tree, very like the common alder. 



C. faginea Lindl., Wall. PI. 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 differs in the form and margin of the leaf, 

 and in the bracteas. (Wall. PI. As. Rar., 2. p. 5.)

 lucral scales in pairs, hairy at the base, a pair growing together at their 

 opposed edges, and constituting an inflated covering to the opening. Calyx 

 investing the whole ovary, and extended at the tip into a very short ciliate
