56296. "(No. 6751. October, 1922.) A tall tree, 70 to 80 feet 
in height, found on the slopes of the Likiang Snow Range at an altitude 
of 10,000 feet. The thick, leathery leaves are silvery beneath and the

feet high, with a trunk 2 to 3 feet in diameter, found in the mountains 
north of Tengyueh at altitudes of 7,000 to 8,000 feet. The small, el-

casuarina suberosa ( Casuarinaceae ) , 56564. From Hobart, Tasmania. 
Seeds presented by L-. A. Evans, Secretary of Agriculture, Agricultural 
and Stock Department. A tree 30 to 40 feet tall, quite similar to 
Casuarina equiseti folia, with smooth, slender branchlets. It is considered 
a valuable fodder tree in the interior districts which are subject to 
drought. The wood is of great beauty for cabinetwork, but should be 
used only in veneers, as it is apt to split in drying. (Adapted from 
Maiden, Useful Native Plants of Australia, pp. 122, 399, and from 
Bentham, Flora Australiensis , vol. 6, p. 197.) 
cervicina gracilis ( Campanulaceae ) , 56565. From Hobart, Tasmania. 
Seeds presented by L. A. Evans, Secretary of Agriculture, Agricultural 
and Stock Department. A very variable species, either a slender annual 
6 to 18 inches high or a perennial with a rootstock which is almost
