10, Alnus? sp. n., affinis A, Japouicay Sieb. et Zucc. 



A single small specimen, with a few male amenta and very young

 not identical as far as can be judged by a comparison with a fruiting 

 specimen, wuth adult leaves communicated by Dr. Blume.

Houfkono-. These specimens agree with one from Japan, communi- 

 cated to me by the late Professor Zucearini, in every respect except 

 that the leaves are rather broader.. The foliage is very near that of 

 some varieties of the common East Indian J/, inleyrijolia, Eoxb. {M.
