Salix fargesii Burkill

In the original description of Salix fargesii, the ovary was described as pilose; however, because glabrous ovaries were found in the isotypes by K. O. Seemen (Bot. Jahrb. Syst. 29: 277. 1900), his opinion was that the ovary of the type was glabrous. According to observations of the authors, as well as many other collections from the type location, the ovaries are either of two forms: pilose or glabrous. Therefore, it seems that the type collection (A. Henry 5678) is probably a mixture of these forms. The authors follow I. H. Burkill’s opinion, and treat the form with the pilose ovary as the autonymic variety. The name Salix fargesii var. hypotricha N. Chao (Bull. For. Pl. Res. 3: 5. 1985), requires further study as to its identity.

Catkins 6-8 cm; peduncle 1-3 cm, with leaflets; bracts narrowly obovate, ca. 1 mm, densely villous, apex rounded. Male flower: adaxial gland rectangular, abaxial gland broadly ovate, very small; stamens 2, glabrous. Fruiting catkin to 12 cm. Female flower: adaxial gland broadly ovate; ovary long pubescent or glabrous, shortly stipitate; style ca. 1 mm, 2-lobed; stigma 2-cleft. Capsule oblong-ovoid, pilose or glabrous, shortly stipitate.

Salix fargesii (川鄂柳), the Farges willow, is a species of flowering plant in the willow family (Salicaceae), which is native to Gansu, Hubei, Shaanxi, and Sichuan in China. It inhabits mountainous areas at 1,400–1,600 m (4,600–5,200 ft).

Growing to 3 m (9.8 ft) in height, it is a spreading deciduous shrub with prominent new green growth which turns a shiny brown in its second season. Bright red buds appear in winter, followed by erect catkins. The leaves are glossy green on the upper (abaxial) surface, and dull grey on the lower (adaxial) surface. It has gained the Royal Horticultural Society’s Award of Garden Merit.

The specific epithet fargesii commemorates Paul Guillaume Farges (1844–1912), a French missionary and botanist who sent many plant specimens back to Europe, where they were unknown at that time.
