Shrubs or small trees, (1.5-)2-5(-10) m tall. Bark dark brown. Branchlets slender, terete, striate, rusty- or white sericeous when young but glabrate when mature. Buds small; bud scales thick, densely rusty- or white sericeous. Leaves alternate; petiole 0.5-1 cm, concave-convex, densely appressed sericeous-pubescent initially but soon sparsely so; leaf blade glaucous and opaque abaxially, green and slightly shiny adaxially, elliptic-lanceolate to ovate or broadly ovate, (4-)5-11 × (1.5-)2-6 cm, subleathery, densely rusty- or white sericeous on both sur-faces when young, ± sericeous abaxially and glabrate adaxially when mature, trinerved, midrib and basal lateral veins elevated abaxially, always impressed adaxially, basal lateral veins arcuate-ascendant and up to 1/2-3/4 of leaf blade, axils of basal lateral veins sometimes dome-shaped abaxially and slightly bullate adaxially, other lateral veins all small, reticulate with transverse veins and veinlets, base acute to cuneate and always unequal on both sides, apex acuminate. Glomerules axillary, (1-)4-6(-10)-flowered; bracts triangular-subulate, ca. 0.5 mm, densely rusty sericeous-pubescent. Pedicels slender, ca. 5.8 mm, densely rusty sericeous-pubescent. Flowers small, yellow-green. Perianth tube very short; perianth lobes 6, triangular-ovate, subequal, outer ones ca. 1.8 × 1 mm, inner ones ca. 2.2 × 1.4 mm, all densely sericeous-pubescent outside and inside, acute. Fertile stamens 9, ca. 1.25 mm; filaments of 3rd whorl each with 2 orbicular-reniform glands at base, others glandless; anthers of 1st and 2nd whorls rectangular or ovate-rectangular, somewhat shorter than dilated filament, 4-celled, cells arranged in an almost transverse series, upper 2 introrse, lower 2 lateral-extrorse, anthers of 3rd whorl 4-celled, upper 2 cells small and lateral-extrorse, lower 2 cells large and extrorse. Staminodes subspatulate or ovoid, stalked, including villous stalk 0.6-0.8 mm. Ovary ellipsoid-ovoid, ca. 1 mm, sessile, glabrous, attenuate toward apex; style short; stigma discoid. Mature fruit red, ovoid, 1-1.5 × 0.7-1 cm; perianth cup in fruit crateriform, 5-8 mm wide on top; perianth lobes in fruit persistent, slightly dilated and wilting; fruit stalk slender, 0.7-2 cm, gradually dilated toward apex. Fl. Apr-Sep, fr. Sep-Jan of next year.

Essential oil distilled from the leafy branchlets (0.8%-1.7%) is used for cosmetics or medicine. The drupe contains oil or fat, which is used in soap manufacture. The leaves are used by local people for treating rheumatic disorders.

● Thickets, forest margins, sparse or dense forests along riverbanks, watersides, limestone hills; 1100-2300 m. S Sichuan, SE Xizang, Yunnan.
