Other Species of A'lnus. A. barbata Meyer (our 

 fig. 1522.), A. obtusifolia Royle, is very abundant 

 on the banks of the Jumna and Tonce. A. 

 elongdta Royle occurs in Cashmere ; and A. ne- 

 palensis Wall. (PI. As. Rar. t. 131.) on the moun- 

 tains surrounding 

 the valley from 

 which it was named. 

 (Illust. p. 341.) It 

 appears probable, 

 that A. nepalensis, a 

 tree from 30 ft. to 

 4 ft. high, may prove 

 sufficiently hardy to 

 bear the climate of 

 London. A. subcor- 

 ddta Meyer (owe fig. 

 1523.) was raised 

 from seeds in the 

 Birmingham Bo- 

 tanic Garden in 

 1838 ; and A.jorullensis in the Horticultural Society's Garden in 1839.

doubly serrated, glabrous above ; the

 elliptic, blunt, 

 repand, or ob-
