Shrub or small tree, branches silky-tomentose, leaf stipulate, stipule minute or semicordate, coarsely toothed; petiole c. 0.5-1-(1.7) cm long; lamina c. 5-11-(15) x 1.5-3.1-(6) cm, ovate-lanceolate or oblong-lanceolate, entire or glandular serrulate, tip acute-acuminate, silky on both the surfaces when young, nearly glabrous when mature or persistently silky on both the sides. Flowers before or with the leaves. Male catkin c. (1.5)-2.5-3-(4) x 1-1.5 cm, 1-4 leaves at the base, rachis villous. Peduncle 1-10 mm long. Bract 1.2-2.2 x 0.4-0.8 mm, brown to black.

Fl. Per.: March-June.

Type: In Nepalia, Kumaon, Sillet, 1821, Wallich sub nomine S. grisea Wall. Cat. No. 3700 (K, L, LE).

Distribution: Afghanistan, Pakistan (Chitral, Kurram, Swat, Gilgit, Hazara), Kashmir, India, Nepal, Bhutan, Tibet, N. Mynamar; China (Gansu, Guizhou, Hebei, Hubei, Hunan, Nei Mongol, S. Qinghai, Shaanxi, Shanxi, Sichuan, Xizang, Yunnan Zhejiang) (F. Zhenfu, Z. Shidong & A.K. Skvortsov l.c.).

Salix wallichiana Andersson may be distinguished from S. dolichostachya Flod. by having densely silky ovary, on a stipe as long as or many times longer then the disk whereas in S. dolichostachya Flod., the ovary (and the fruit) is glabrous and subsessile. According to Parker (For. Fl. Punj. ed. 3: 501. 1956) specimens showing male catkins only are distinguishable with difficulty from S. dolichostachya Flod. (S. daphnoides sensu Brandis non Villars).

Kimura (in Hara, Chater & Williams, Enum. Fl. Pl. Nepal 3: 218. 1982) has tried to establish that Salix disperma Roxb. ex D. Don is conspecific with S. wallichiana Andersson. However, the reasons advanced are not convincing enough. Recently, F. Zhenfu, Z. Shidong & A. K. Skvortsov (in Wu Zheng-yi and P. H. Raven, Fl. China 4: 171. 1999) have treated S. disperma Roxb. ex D. Don as a synonym of S. tetrasperma Roxb.
