Inter species subsectionis Macranthorum flore parvo ad C. yunnanense accedens sed ovario pubescenti, petalis non tortis, staminodio oblongo 1-l.l cm longo, 5- 6 mm lato subduplo longiore quam latiore, sepalo dorsali longiore quam latiore. Terrestrial herb, 13-15(-24) cm tall, with stout rhizome 4-5 cm long and 4-5 mm thick. Stem glabrous, bearing 2-3 sheaths at base and 3-4 leaves well spaced above pointing upward. Leaves elliptic or elliptic-lanceolate, 4.5-11 cm long, 2.8-3.5 cm wide, acuminate or subacute, sheathing and amplexicaul at base, glabrous above, minutely pubescent or glabrescent beneath, ciliate.

Pedicel and ovary 1.7-2 cm long, pubescent at least along the ribs; flower 4-4.5 cm across, purple-red; dorsal sepal elliptic-ovate, 2.2-3 cm long, 1.3-1.5 cm wide, acuminate, glabrous; synsepal ovate-elliptic to narrowly elliptic, 2.2-2.8 cm long, 1-1.2 cm wide, bifid at apex, glabrous; petals lanceolate, 2.6-3 cm long, 7-9 mm wide, villose in basal half of adaxial surface; lip deeply pouched, obovate-subglobose, 2.5-3 cm long, 1.5-2 cm broad, pu bescent inside, glabrous outside, with mouth ca. 1.2-1.4 cm across; staminode oblong, 1-1.1 cm long, 5-6 cm wide, longitudinally grooved along the midrib, carinate beneath, mucronate at apex; filaments linear, 3 mm long.
- Distribution
-
Cypripedium is mainly a temperate genus, consisting of about 45 species (Cribb, 1997) distributed largely in eastern Asia and North America. Over two-thirds of the species, about 32, are found in China (Chen & Xi, 1987; Chen & Tsi, 1998). Some species are of phytogeographic significance, several pairs of vicarious species being disjunctly distributed in eastern Asia and eastern North America (Chen, 1983a).
