備註: FOHK引用香港毛蘭的拉丁學名Eria gagnepainii有誤,在The Wild Orchids of Hong Kong也有詳細描述(p 498) 可能在香港野外滅絕的原生植物, 此圖植株是攝於中國大陸。 本種最初於1933年在馬鞍山西南方坡被發現, 之後再沒有紀錄。現已知分布於中國大陸(廣西、雲南至西藏南部)、台灣和越南。 參閱文獻: Gloria Barretto, Phillip Cribb and Stephan Gale, The Wild Orchid of Hong Kong, Natural History Publication (Borneo), 2011. thanks Edward Ng's info FOHK: Epiphytic herb, glabrous throughout; rhizome creeping, 4–5 mm in diam., with funnel-shaped sheaths 0.7–1.5 cm.
