p.62). S.brachista also is nearly related to S. Lindleyana Andersson, which differs 
in its more glaucous leaves, in the glabrous filaments and in the much broader ven- 
tral gland. 
The specific name is derived from Spdaxtaros, very small.

This is a very small, flabellately branched, prostrate shrub. The leaves are green- 
ish beneath; their nerves are impressed above, and do not show on the lower surface; 
the serration is rather deep, and the teeth are incurved, or the leaves are rather 
trilobate at the apex. The bracts, at least of the c" plant, are slightly lobulate; 
the filaments are glabrous.

S. secta Hooker f. seems to be only a very small form of S. oreophila Hooker f., 
differing in its smaller, somewhat broader leaves, which are lobulate at the apex 
(foliis cuneatis apice 3-5-fidis). The bracts in the male co-type before me are ob- 
tuse at the apex and the filaments are glabrous as in the type of S. oreophila. It 
resembles the European S. serpyllifolia Scopoli. These are, so far as I know, the 
smallest Willows known.

According to Hooker, this is “ a very small gnarled shrub, with ascending branch- 
lets." I have seen the types the leaves of which apparently are not yet fully devel- 
oped. The d flowers have two very long and narrow glands, the dorsal being 
scarcely smaller than the ventral. They are about half as long as the oblong glab- 
rous bracts which are ciliate and somewhat emarginate at the apex. The free 
rous filaments are only 34 longer than the bracts. The flowers apparently are not 
in a normal condition, the ovaries being narrowly oblong with short sessile stigmas. 
Andersson says: “ capsulis breviter pedicellatis ovatis glabris, stylo mediocri 
stigmatibus brevibus." The gland is rather broad, ovate-rectangular, truncate OT 
emarginate at the apex; the bracts are glabrous, broadly obovate, crenulate at the 
apex, nearly enveloping the ovaries. The younger branchlets and leaves are loosely 
covered with long silky hairs. 
A c specimen, collected by G. Forrest, Yunnan, Tali Range, alt. 3300-3800 m., 
August 1906 (No. 4603), which was named S. microphyta Franchet by Diels (in 
Not. Bot. Gard. Edinburgh, VII. 252 [1912]) looks very much like S. cal 
The flowers have glabrous filaments and two rather large and broad glands. The 
Yunnan plant, however, differs widely from S. microphyta Franchet (see p. 62) 
&nd may represent a new species; certainly it needs further study.
