Androcorys pugioniformisBasionym is Herminium pugioniformis Lindley ex Hooker f., 1890, published in Flora of British India 6: 130. 1890. A synonym is Herminium nivale Schlechter, 1924, published in Särtyk ur Meddelanden från Göteborgs Botaniska Trädgård (Acta Horti Gothoburgensis) 1: 134. 1924; based on a type collected above the Huanglong valley by H. Smith July 21s t 1922. Another synonym could be Porolabium biporosum (Maximowicz) T. Tang & F.T. Wang, 1940, published in Bulletin of the Fan Memorial Institute of Biology 10: 38. 1940.
Androcorys pugioniformis was recorded from Huanglong by Schlechter in 1924 as Herminium nivale but hasn’t been seen in the park yet by the authors. Harry Smith found it in scree above the Huanglong valley at an altitude of perhaps 4000-4100 m (his published altitude of 4800-5000 m is likely 700 m too high). The Flora of China reports the species from coniferous forests, alpine thickets and meadows at altitudes between 3400-5200 m from eastern to southern Qinghai, northwestern Sichuan, Tibet and northwestern Yunnan. The plant carries a single leaf, is 5.5-18 cm high and has uniformly green flowers with a diameter of 2.5-3 mm. Pearce and Cribb (2002) report that A. pugioniformis resembles Porolabium biporosum (Maximovicz) T. Tang & F.T. Wang, 1940. In their publication of the genus Tang & Wang note that Porolabium differs from Herminium by the stigma which is not attached to the processes of the rostellum, but otherwise very similar to Herminium and Androcorys. The German orchidologists Ursula and Dietrich Rueckbrodt recorded Porolabium cf. biporosum from Jiuzhaigou at June 19, 1999, where it grew at approx. 2900 m in dense shrub. Further investigations in the field and in herbaria are necessary to clarify matters.
Flowering: July-August (June).
