Bloodstained Ptysiglottis (Ptyssiglottis sanguinolenta)
The Bloodstained Ptysiglottis was described in the year 1791. The plant occurred in the districts of Colombo, Galle, and Ratnapura in the south of the island of Sri Lanka, where it grew with prostrate stems on wet rocks in several rivers of the rain-soaked lowland forests.
The species was repeatedly searched, but it could never be relocated – it is with nearly absolute certainty extinct.
