Young branches brownish, slightly angled, without lenticels, yellowish-brown tomentose, glabrescent and becoming greyish-white when older. Perennating buds dimorphic (floral perennating buds are at least twice the size of vegetative perennating buds).

Inflorescence racemose, usually axillary on biennial branches, 7 - 16 - flowered. Peduncle usually very short, inflorescence rachis pale green, 0.7 - 3 cm long, yellowish-brown tomentose, glabrescent when fruiting; bracts pale green, obovate, cucullate, 6 - 8 x 4 - 6 mm, abaxially yellowish-brown tomentose or pubescent, adaxially glabrous, margin ciliate, caducous; bracteoles 2, inserted at base of pedicel, pale green, linear, 5 - 6 x ca. 0.2 mm, ciliate, caducous. Pedicel pale green, 2.5 - 4.5 mm long, yellowish-brown tomentose or pubescent or nearly glabrous, articulate with the hypanthium. Hypanthium green, cupuliform, 1.5 - 2.0 x 1.2 - 1.5 mm, glabrous; calyx limb lobed nearly to base, lobes 5, green, triangular, ca. 1.5 x 1 mm, apex acuminate, margin ciliate, with denser and longer cilia at apex. Corolla white or virescent, sometimes tinged with red on angles when young, urceolate to spherical, slightly angled when young, 4.5 - 6 x ca. 4.5 mm, glabrous outside, pubescent inside, 5 - lobed; lobes ovate-triangular, reflexed, ca. 1 x 1.2 mm. Stamens 10, 4 - 4.5 mm long; filaments flat, slightly S-shaped, 1.5 - 2.0 mm long, puberulous and pubescent adaxially, slightly puberulous abaxially; anthers 3.0 - 3.5 mm long, thecae 1.5 - 1.7 mm long, tubules narrower than the thecae, 1.5 - 1.8 mm long, each with an oblique pore 0.7 - 1.0 mm long, 0.2 - 0.3 mm in diam.; spurs 2, borne at abaxial base of tubules, 0.8 - 1 mm long, echinate. Disc yellowish, annular, glabrous; style cylindrical, slightly angled in sicco, 5.0 - 5.2 mm long, glabrous, stigma punctate; ovary pseudo- 10 - locular, each locule with 8 - 10 ovules. Fruiting pedicel 4 - 11 mm long, expanded at apex; berry green when young, turning dark red later and finally dark purple at maturity, globose, 4 - 6.5 mm in diam., glabrous, with persistent calyx lobes appressed at apex. Seeds ovoid, 1.2 - 1.5 x 0.8 - 1 mm, testa brownish, reticulate, soft.	en	Tong, Yi-Hua, Zhao, Wang-Lin, Wang, Bing-Mou, Liu, En-De, Cai, Jie, Guo, Yong-Jie (2021): Vaccinium motuoense (Ericaceae), a new species from Xizang, China.
