The genus Rhynchostylis, abbreviated as Rhy in horticultural trade, is a member of the Orchid family (Orchidaceae), consisting of 3 currently species native to the Indian Subcontinent, China, Indochina, Malaysia, Indonesia and the Philippines.[1][2]

These orchids grow naturally in warm, moist, shaded tropical areas. Hobbyists wanting to grow them will need a warm, humid growing environment with gentle air movement. Their unusually fragrant blooms often appear in the slightly cooler Winter months.

Despite being in the Vanda Tribe, they are very different from Vandas. They grow more slowly, their roots are more fragile, and almost any direct sun will harm them. However, they are typically grown with no potting mix on slat baskets or mounted just like Vandas.[3] [4]

The Subtribe was changed from Sarcanthinae (Benth, 1881) to Aeridinae (Pfitzer, 1887) in 1972.[5][6]
