Rhododendron apiculatum Rehder & E. H. Wilson; R. benthamianum Hemsley; R. concinnum var. benthamianum (Hemsley) Davidian; R. concinnum f. laetevirens Cowan; R. concinnum var. lepidanthum (Rehder & E. H.

Balfour ex Hutchinson; R. yanthinum Bureau & Franchet; R. yanthinum var. lepidanthum Rehder & E. H. Wilson.
Shrubs, (0.4–)1.5–3 m tall; young shoots scaly. Petiole 5–13 mm, densely scaly; leaf blade oblong, elliptic, ovate, oblong-lanceolate or ovate-lanceolate, 2.5–7.5 × 1.5–3.5 cm; apex acuminate to acute, apiculate; abaxial surface pinkish green or brown, scales 0.5(–1) × their own diameter apart or contiguous, unequal, with obvious margin; adaxial surface ± scaly, sometimes pubescent along midrib. Inflorescence terminal or subterminal, umbellate, 2–5-flowered. Pedicel 0.4–1.8 cm, densely scaly; calyx 5-lobed; lobes 0.8–1.5(–6) mm, rounded, triangular or oblong, sometimes undeveloped and rim-like; corolla broadly funnelform-campanulate, pale or deep purplish red, inside with or without brownish red spots, 1.5–3.2 cm, outer surface ± scaly, glabrous or sparsely pubescent at base; stamens unequal, as long as corolla; filaments pubescent below; ovary 5-locular, densely scaly; style slightly longer than corolla, usually glabrous, rarely pubescent at base. Capsule cylindric, 10–15 mm. Fl. Apr–Jun, fr. Sep–Oct.
Abies-Rhododendron forests, thickets on slopes; 2300–3000(–3800) m. Guizhou, Henan, Hubei, Shaanxi, Sichuan, Yunnan.
It is believed that Rhododendron hutchinsonianum W. P. Fang (Acta Phytotax. Sin. 2: 83. 1953), described from Xizang, is a variant of R. concinnum (see Cullen, Notes Roy. Bot. Gard. Edinburgh 39: 76. 1980).
