SALICACEAE. — SALIX 69 



nescentes utrinque longe sericeas ^ superans; ovaria sessilia, breviter 

 sericea, crasse ovata, stylo breviter subbifido divaricate stigmatibus 

 oblongis brevibus bifidis coronata; glandula ut in flore cf, bracteis 

 iis floris d" similibus aequilonga, medium ovarii subaequans. Fructus 

 brevissime pedicellati, sparse sericei, circiter 3 mm. longi. 



Western Szeeh'uan: Wa-shan, thickets, alt. 2300-2600 m., June 

 1908 (No. 2138, type; bush 3-5.4 m. tall; 9 ; No. 2138% d^); Mupin, 

 woodlands, alt. 2300-3300 m., June 1908 (No. 2144; bush or small tree, 

 4.5-6 m. tall; 9 flowers and fruits). 



At the first sight this species is not unUke S. heterochroma Seemen in the shape 

 of the leaves and of the catkins. But S. hylonoma may be easily distinguished from 

 it by its serrate leaves, which are smooth and somewhat waxy, not reticulate be- 

 neath, and by the long narrow gland of the flowers. See also S. isochroma 

 Schneider (p. 122), which differs in the greenish and reticulate under surface of the 

 leaves. A specimen from Hupeh (Henry's No. 5296) was referred by Burkill to S. 

 longiflora (see my remarks under S. Wallichiana Andersson, p. 65), but it seems to 

 have only a single stamen. The nearly sessile silky catkins are 2.5 long and 1 cm. 

 thick, and are not unlike those of S. Wallichiana and of S. heterochroma. The 

 bracts are narrow and acute, somewhat like those of S. gracilistyla Miquel. The 

 gland is short Q/^ the length of the bracts), rather broad and rectangular. 1 

 have seen no other specimen from central China which I could place with Henry's 

 number. If the presence of only one stamen is a normal condition this number 

 may represent an undescribed species of this section. 



The specific name is derived from vXovofios, living in woods.
