桃叶杜鹃(原亚种) tao ye du juan (yuan ya zhong)

Shoots stout. Leaf blade 7–10 × 2–3 cm; apex acuminate. Inflorescence 6–10-flowered. Pedicel 1–2 cm; corolla white to purple, with deep purple flecks, 2–3 cm. Fl. Jun–Jul, fr. Aug–Oct.

Evergreen broad-leaved forests, thickets; 1200–1800 m. C and W Guizhou.

One of us (Chamberlain) has seen specimens originating from Guiyang, the type locality of subsp. annae, with flowers up to 4.5 cm and lacking flecks; both characters suggesting subsp. laxiflorum. There is also considerable overlap in the leaf dimensions. It is possible that subsp. laxiflorum is synonymous with subsp. annae.
