Rasna Orchid

Vanda tessellata, the grey or checkered orchid, is an epiphytic orchid that clings to tree trunks across the Indian subcontinent and Indochina. It has thick aerial roots and fragrant flowers patterned in a grey-green chequer with a violet lip.

In parts of India it is used as a source of Rasna, a herb that Ayurveda values in traditional preparations for joint comfort, with the root and leaf being the parts used. Like all orchids it is listed under CITES, so it is restricted in trade and not offered.
