× Holcosia taiwaniana is a natural hybrid of the orchid species Holcoglossum quasipinifolium and Luisia teres. It is an epiphyte endemic to Taiwan.
Description The occasionally branched, pendulous, terete stems are 30 to 60 cm in length and 4 to 4.5 mm wide. The terete, 14 to 21 cm long and 2 to 3.5 mm wide leaves are not strictly distichously arranged, but rather laxly alternate. Two 4–5 cm wide, yellowish flowers are produced on 2 to 3 cm long inflorescences. The labellum bears brown-red longitudinal stripes."Flora of China v 25 pp. 477–478, 凤蝶兰属 feng die lan shu, Papilionanthe Schlechter, Orchis. 9: 78. 1915." H. taiwaniana bears a resemblance to H. pseudotaiwaniana, but lacks the latter's distinct wedge-shape along the epichile.
