Western Szech'uan: mountains west of Tachien-lu, alt. 2600— 
3800 m., June 1904 (No. 4518, type; tree 6-7 m. tall; 7); same local- 
ity, September 1904 (No. 4518*; with fruits). 
This species seems most nearly related to S. pentandra Linnaeus and may rep- 
resent only a variety of that species. The c' specimen differs from those of S. 
pentandra collected in the Altai Mountains only in the broader glands, the shape 
of which is very variable in both the species. The fruiting branch bears on the 
upper part leaves which are very whitish underneath. 1 have not seen or found a 
description of a form of S. pentandra Linnaeus with such leaves. 'The 9 flowers 
may present some better differences, but the fruits are very much alike. 
There is a sterile specimen from western Hupeh: Changyang Hsien, alt. 800 m., 
November 1907 (No. 1441; tree 18 m. tall, girth 2 m.); the leaves of which are 
glabrous and white tinged with red beneath. They are elliptic-lanceolate, from 
6-10 cm. long and from 2-3.5 em. broad (others are deformed); the petioles are 
from 8-10 mm. long and bear two glands; the stipules are semicordate, half as 
long as the petioles and glandular-serrate. From this very tree Mr. Wilson sent 
euttings to the Arnold Arboretum, from which a young plant is growing very freely. 
The leaves are ovate- or elliptic-lanceolate, acute at the base and acuminate at the 
apex, measuring from 8 to 11 cm. in length and from 2.5 to 3.6 em. in width. They 
show the same white color underneath. I suppose that No. 1441 may belong to 
this new species. 
The specific name is derived from mapanAnjouos, resembling. 
The specimens of my No. 1441 came from a tree which is common in one locality 
in Changyang Hsien growing by the side of watercourses between altitudes of 
from 700 to 800 m. This tree grows tall (20-25 m.) and has a straight, rather 
slender trunk and dark gray deeply fissured bark. The branches are rather sparse, 
Short, spreading, rather slender, and form a loose oval crown. Pictures of this 
tree will be found under Nos. 584 and 586 of the collection of my FTO um 
and in my Vegetation of Western China, Nos. 459 and 460.
