Cladrastis Wilsonii is closely related to C. shikokiana Makino, from which it 

 differs in the very shortly stalked, broader and hirsute pod. The leaves of the 

 two species are similar; the indumentum, however, of the young leaves of 

 C. Wilsonii is white or very pale yellow, and that of C. shikokiana is brown. 



This tree is fairly common in the moist woods of western Hupeh but rare in 

 Kiangsi and not reported west of the eastern limits of the Red Basin of Szech'uan, 

 where it is replaced by C. sinensis Hemsley. This is easily distinguished from 

 C. Wilso7iii by the glabrous ovary and narrower, more numerous leaflets generally 

 oblong and rounded or nearly rounded at the base and more or less villose along 

 the midrib; the flowers, too, are somewhat smaller and the panicles larger, occa- 

 sionally attaining 30 or 40 cm. in length. A. R. and E. H. W.
