Salix [unranked] Subviminales Seemen, Salic. Jap. 20. 1903; sect. Gracilistylae C. K. Schneider.

Shrubs rarely creeping. Branchlets at first pilose, glabrescent. Leaf blade obovate, narrowly obovate-oblong, or obovate-elliptic, rarely suborbicular, margin serrate, rarely entire. Flowering precocious. Catkins terete or ellipsoid, sessile; bracts 2-colored or nearly black, ovate to narrowly oblong-lanceolate. Male flower: gland solitary, adaxial; stamens 2, rarely connate throughout, or only filaments connate or partly connate; anthers red. Female flower: ovary densely pubescent, sessile; style slender, rarely short; stigma narrowly oblong.

A. K. Skvortsov indicates that this is a very heterogeneous section. Of it, Salix lanifera, S. myrtillacea, and S. taoensis seem to be more related to sect. Caesiae, while S. obscura may belong to sect. Vimen.
