× Holcosia taiwaniana is a natural hybrid of the orchid species Holcoglossum quasipinifolium and Luisia teres. It is an epiphyte endemic to Taiwan.
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.[1]
