Description


The 1 cm long stems produce 4-5 oblong to subelliptic, 6.5-8 cm long and 2.6-3 cm wide leaves and greenish, well developed, dorsiventrally flattened, verrucose roots. The leaves often show purple colouration of the abaxial surface and they are shed before flowering, but sometimes 1-2 leaves persist. Flowering occurs throughout April to July. Widely and simultaneously opening, pink flowers are produced on 1-2 suberect or arching, 10-15 flowered racemes. The plants are epiphytes or lithophytes on damp rock found at elevations of 800-2200m a.s.l.[3] The chromosome count is 2n = 2x = 36.[4]


Taxonomy


This species is placed within the subgenus Aphyllae, which is characterised by deciduous leaflessness. A source of taxonomic confusion has been the missapplication of this species name to Phalaenopsis honghenensis.[5] Phylogenetic analysis indicated Phalaenopsis wilsonii was closely related to Phalaenopsis lowii.[6]


Conservation


This species has been categorized as vulnerable in China Species Red List.[7] It is protected unter the CITES appendix II regulations of international trade.[8]
