Sunipia nepalensis, a new orchid species from Nepal is described and illustrated. Notes to distinguish it from related taxa
Key words: orchid, taxonomy, Himalaya
Sunipia Lindley (1826: 21, 25), (including Ione Lindl.) is a genus of about 23 species in the world (Govaerts
et al. 2011) restricted to southeast Asia. Until now it is known from Bhutan, China, India, Laos, Myanmar,
Nepal, Taiwan, Thailand and Vietnam (Seidenfaden 1969, 1986, Pearce & Cribb 2002, Chen & Vermeulen
2009). In Nepal Sunipia is represented by three species, namely S. bicolor Lindley (1833: 179), S. cirrhata
(Lindl.) Hunt (1971:184) and S. scariosa Lindley (1833: 179, = S. racemosa (Smith) Tang & Wang 1951: 90).
A species of Sunipia was collected by the first author during an orchid survey in the Daman Makawanpur
District, central Nepal. The characteristics of this plant do not match any of the previously described species
in the genus. Therefore it is illustrated and described here as a new species.
