148 WILSON EXPEDITION TO CHINA

Not. Bot. Gard. Edinburgh, VII. 119 (Pl. Chin. Forrest.) (1912). 
CHINA. Yunnan: “ Maeul chan, and rocks of Lao long tong above Yen-tze- 
hay at 11000 ft." also “ Li chiang at 12500 ft., always on a calcareous formation,” 
J. Delavay (Nos. 2200, 3105, 4323, 4678, ex Burkill) ; ** summit of exposed cliffs form- 
ing a side valley on the eastern flank of the Lichiang range, alt. 10000-10500 ft., 
June 1906,” G. Forrest (No. 2318; shrub 0.6-0.9 m. tall; ex Diels). 
I have not seen a specimen of this Willow, which seems to be most nearly related 
to S. opsimantha Schneider (p. 63). Burkill placed it in sect. Viminales, but 
according to his description it may be better placed in sect. Glaucae, and certainly 
it does not belong to sect. Viminales. 1t also resembles some species of sect. 
Eriostachyae.

The species of this section are distinguished by the long pedicels and by the short

According to Komarov the S. cinerea of his Flora Manshuriae is S. gracilistyla 
Miquel (see p. 164), but von Seemen apud Siuzev mentions two varieties of this va- 
riable species and he also mentions S. Thunbergiana Blume, which is only a synonym 
of Miquel's species. Unfortunately I have not seen any specimens of either from 
Pee. authors apparently did not use the term Capreae to designate 2 natural 
section.
