1917] SCHNEIDER—NEW CHINESE PLANTS 145 
3500 m., mense Augusto 1914, C. Schneider (no. 3454; ramuli fructiferi in Herb. 
Schneider). . 
It is with some hesitation that I refer this female willow to S. brachista 
Schn., which is known only from male specimens collected by E. H. Witson in 
western Szechuan. In most of my specimens there are no flowers or fruits, 
the apex of the | hlets being infected probably by an insect and transformed 
into hairy galls. The leaves agree well with those of typical S. brachista in the 
nervation and color. 
Together with no. 3454, I collected another female willow (no. 2318), the 
leaves of which are even a little smaller, of a somewhat firmer texture, with 
veins slightly impressed above and scarcely visible on the rather bluish grey 
under surface. I am not sure whether or not this form belongs to the Hima- 
layan S. Lindleyana Wall. or represents a form of S. Souliei Seemen. It is not 
quite identical with those female plants from Tachien-lu which I described in 
Pl. Wils. 3:62 as S. Souliei. I think it best, therefore, to give the following 
description of no. 2318 from the snow mountains near Lichiang-fu: 
Frutex pygmaeus facie S. Lindleyanae Wall. vel S. serpyllifoliae 
Scop. ramis solo vel rupestribus adpressis, ramulis brevibus junior- 
ibus olivaceis glabris (an novellis pilosiusculis?). Folia perparva, 
crassiuscula, elliptica vel ovato-elliptica, utrinque obtusa vel 
subacuta, rarius basi subr. minimis exceptis 5-7 mm. longa, — 
2-3 mm. lata, superne satis laete viridia, glabra vel in costa incisa 
sparse pilosa, nervis lateralibus plus minusve distincte incisis,
