Part shade Cold Summer

Common Name The Curved Platanthera - In China Gong Bei She Chun Lan

Flower Size .6" [1.5 cm]

Found in Tibet to Yunnan Province of China in forests, scrub and grasslands on slopes at elevations of 1900 to 3930 meters as a small to just medium sized, cold growing terrestrial with a creeping, cylindric, stoloniferous rootstock giving rise to an erect to ascending stem with 1 to 2, tubular, basal sheaths and carrying 2, elliptic to obovate, acute to acuminate, basally clasping leaves that blooms in the summer on an erect, slender, 2.2 to 4.8" [5.5 to 12 cm] long, 4 to 10+ flowered inflorescence with 1 to 2, foliaceous bractsw and lanceolate, acuminate to acute floral bracts.

CAUTION!!! Kew has this species synomonous with P bhutanica but I have left them separate pending more research. P bhutanica flower photos match the references better than the photos above but not the plant and leaves which in the Flora of China drawings are only 2, broadly elliptic, obtuse and not undulate.

Synonyms Habenaria platantheroides Tang & F.T.Wang 1936; Platanthera platantheroides K.Y.Lang 1989
