SALICACEAE. — SALIX 69 
nescentes utrinque longe sericeas 14 superans; ovaria sessilia, breviter 
sericea, crasse ovata, stylo breviter subbifido divaricato stigmatibus 
oblongis brevibus bifidis coronata; glandula ut in flore , bracteis 
iis floris à similibus aequilonga, medium ovarii subaequans. Fructus 
brevissime pedicellati, sparse sericei, circiter 3 mm. longi. 
Western Szech'uan: Wa-shan, thickets, alt. 2300-2600 m., June 
1908 (No. 2138, type; bush 3-5.4 m. tall; 9; No. 2138*, 9); Mupin, 
woodlands, alt. 2300-3300 m., June 1908 (No. 2144; bush or small tree, 
4.5-6 m. tall; o flowers and fruits). 
At the first sight this species is not unlike 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 asinglestamen. 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 (L4 the length of the bracts), rather broad and rectangular. I 
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 
Inay represent an undescribed species of this section. 
The specific name is derived from éAovdpos, living in woods.
