SALICACEAE. — SALIX 101 



12 cm. in length and to 3.3 cm. in width. The fruiting aments of the type are 

 without the leafy peduncle and are from 10-14 cm. long and 1 cm. thick, while 

 Faurie's specimen shows only a part of one catkin. The fruits possess a distinct 

 deeply bifid ventral gland; the dorsal gland is very small or wanting. The pedicel 

 is nearly three times as long as the gland and about a quarter the length of the nar- 

 row ovate ovary. Komarov does not mention the style or stigma. 1 have seen 

 only the remnant of a short but distinct, deeply bifid style with narrowish bifid 

 stigmas. The leaves become black in drying, and in their nervation resemble more 

 those of *S. Kusanoi Schneider than those of S. pentandra Linnaeus.

NORTHEASTERN ASIA. Amur: Amur River, 1855, R. Maack (No. 207). 



I have seen only this one specimen from northeastern Asia. Komarov, 1. c, 

 says: "A clar. Korshinskio in provincia Amurensi ad pagum Tambovka solum 

 adhuc coUecta." Wolf, 1. c, mentions " Kamtschatka (Stubendorff; Lubarski; 

 Peters)." Von Seemen keeps " S. bracteosa Turczaninow in Herb. Hort. Petrop," 

 a synonym of S. pentandra, while Wolf refers this form to S. macrolepis Trautvetter. 

 S. pentandra has very smooth leaves and densely flowered cf catkins. The dorsal 

 gland of the ? flowers is often very small or even wanting. The pedicel of the fruit 

 is not much longer than the ventral gland, and the style is rather long and often 

 bifid at the apex. The stigmas of the type are rather short and broad. See also

In Maack's specimen the bracts of the female flowers show several small glandular 

 teeth at the end. The ventral glands of both the sexes are mostly deeply cleft.

CHINA. Kweichau: Pin-fa, March 22, 1902, J. Cavalerie (No. 1317, 

 type; cT). 



Through the kindness of the author, the Arboretum has received some cf and 

 9 flowers of this species. The cf flowers have only 5 stamens (not 12 as Lc^veille 

 says) which are hairy at the base. The bracts are ovate-oblong, somewhat obtuse, 

 and in one ament glabrous with the exception of some hairs near the base within, 

 while in a second ament they are shortly pubescent on both surfaces. There are 

 two different glands forming a nearly 4-lobed disc, the lateral lobes being not very 

 distinct. The 9 flowers are nearly the same as those of S. Wilsonii Seemen, but the 

 stigmas are raised on a rather short but distinct style somewhat like that of S. 

 pentandra Linnaeus. There are also two glands, of which the dorsal one is a little 

 3-lobed. This species needs further investigation.
