Dr. A. Henry writes me :—The Te i huang po of which 
the bark is used here (at I chang) as a drug is Phellodendron 
amurense, Rupr. The northern huang po is probably the 
same. . 
Phellodendron amurense has a yellow inner bark. See 
Ruprecur’s original description of this tree [first discovered 
by R. Maacg, on the Amur river] in Mél. biolog. Acad. 
(1857), p. 526. 
The #8 7X figured in the Phon zo [LXXXII, 2, 3] and 
the santo or kivada, sinice : ii HE, in the Kwa wi [100] 
have not been identified by Francuer. According to the 
late Dr. Geers [see my paper, Bot. quest. conn. Export 
Trade China, p. 4] the latter Chinese name in J apan is applied 
to Evodia glawea, Miq. The bark of this tree is used there for 
tinctorial purposes. This identification has been confirmed at 
London, where authentic herbarium specimens of the tree 
with the bark has been received from J apan. See Pharmac. 
Journ. (1888), p. 785.88 
® Evodia glauca is not the source of the yellow bark in China or Japan: 
and the observations of GrErrs, of the Japanese, and of the Pharmac, 
Journal are wrong. The mistake arose from the fact that Boodia glauca 
and Phellodendron amurense are trees with very similar foliage [ the 
fruit is very different]. Mr, E. M. Houmes, of the Pharmeceutical Museum, 
London, was convinced, by comparing specimens of the commercial 
with herbarium specimens of Hvodia and Phellodendron at Kew, that the 
bark of China and Japan is the product of one tree only, namely 
dron amurense, Rupr.—A, HENRY,
