in C. Jacquemontii the involucre is merely pubescent, the glandular 
bristles being absent, or few and scattered. The tree appears to be 
quite hardy and a vigorous grower; it breaks earlier into growt 
in spring than the Asia Minor tree. 
In the Kew Bulletin for 1911, p. 327, there is a notice of the 
new Chinese form of Corylus Colurna (var. chinensis, Burkill ; 
C, chinensis, Franchet), also a very promising hardy tree. 
XITI.— New Chinese Species. 
Alnus cremastogyne, Burkill [ Betulaceae]. 
Judging by the photographs made by Mr. Wilson of this alder 
as it is found in a wild state in Western China, it forms a slender 
tree sometimes 80 to 100 feet high, of elegant appearance. Its 
leaves are obovate or oval, 24 to 53 inches long, 14 to 3 inches wide, 
broadly cuneate or rounded at the base, acute or cuspidate at the 
apex, unevenly serrate, dark glossy green and glabrous above, with 
tufts of brown hairs in the vein-axils beneath; petiole } to 4 inch 
ong. The female strobiles are very distinct from those of other 
cultivated alders in being solitary on slender peduncles 14 to 
23 inches long; they are ovoid, 2 inch long, 4 inch wide, each seed 
having a thin, broad wing. Should the species prove hardy, as at 
present appears probable, its graceful aspect and distinct character 
will make a welcome addition to trees for damp spots in this 
country. It was discovered by Henry in Szechuen in 1899 and 
introduced by Wilson ten years later. The plants at Kew were 
raised from seed collected by him during his third journey. 
Closely allied to it, perhaps no more than a variety, is A. lanata, 
Duthie, also introduced by Wilson. It has the same strobiles as 
A, cremastogyne, but is well marked by the dense covering of brown 
wool on the branchlets, petioles and peduncles, and on the underside 
of the leaves. No male catkins of A. cremastogyne are preserved 
at Kew, but in A. danata they are slender and 2 to 3 inches long.
