Summary
A new one-flowered species of Nervilia section Linervia is described and illustrated based on material collected in Kanchanaburi Province, southwest Thailand. The white and magenta-spotted labellum and glabrous, angular leaf immediately identify N. hemratii S.W.Gale, Tetsana & Suddee as yet another member of the taxonomically challenging Nervilia adolphi/punctata species alliance, with the purple streaks on the leaf rendering it practically indistinguishable from N. infundibulifolia Blatt. & McCann in the vegetative state. However, the new species differs in the outline and coloration of its labellum, which bears two pubescent ridges on the hypochile and a third on the epichile.
