By the kindness of Mgr. Léveillé I have flowers of his different types except those 
of S. yunnanensis, of which I have seen only one leaf. There seems to be no 
difference in the 9 and g' flowers of the different types. The c flowers have from 
8-12 stamens and a somewhat five-lobed dise. The bracts are ovate-deltoid, rather 
acute, distinctly pubescent on the inner surface and on the margin and often gla- 
brous on the outer surface. The 9 flowers have sessile stigmas, glabrous ! ovaries, 
and are distinctly stalked with pedicels from one-half to three-fifths as long as the 
ovaries. The bracts are like those of the c^ flowers, only in S. Cavaleriei Léveillé 
they are obtuse or even truncate at the apex. There are two glands: the ventral is 
broad and low, embracing the base of the pedicel; the dorsal is 2- or 3-lobed in 
S. Cavaleriei Léveillé and S. polyandra Léveillé, but it is simple and rather large 
in Forrest's plant which might represent a variety. 
An apparently nearly related species is S. anisandra Léveillé et Vaniot (in Fedde, 
Rep. Spec. Nov. UT. 22 [1906]. — Léveillé, Fl. Kouy-Tchéou, 381 [1915]), the type 
of which was collected by J. Esquirol in Kweichou at Pia Fong, March 1905 
(No. 362; à]. It has from 10 to 12 stamens and orbicular-ovate, obtuse and nearly 
glabrous bracts. The two glands seem to be more distinctly separated. This spe- 
cies needs further observation.

NORTHEASTERN ASIA. Transbaikalia: “in virgultis subalpinis Da- 
huriae" N . Turczaninow (type, ex Turczaninow); “ad flumen Selenga prope 
Werchne-Udinsk,” N. Turczaninow (ex Andersson et Wolf). Amur: Stanovoi 
as à nomen nudum, while Weigel (Fl. Pomerano-Rugica, 80 [1769]) first describes it- 
This S. polyandra is the same as S. polyandra Bray (in Denkschr. Bot. Ges. Regensb. 
I. pt. 2, 41, t. 1 (1818]), namely, the hybrid between S. pentandra Linnaeus and S. 
fragilis Linnaeus. S. polyandra Gleditsch (Syst. Einl. Forstwissensch. IL. 4 [1779]) 
is only a synonym of S. pentandra Linnaeus. 
„+ In Fedde, 1. c. (1909), the description is: “ ovariis fusiformibus, pubescentibus, 
vix pedicellatis.” This must be a mistake.
