Thismia domei and T. terengganuensis (Thismiaceae), two new species, and T. javanica, a new record from Terengganu, Peninsular Malaysia

Abstract

Two new species of the mycoheterotrophic genus Thismia Griff. (Thismiaceae), Thismia domei Siti-Munirah and T. terengganuensis Siti-Munirah from Peninsular Malaysia, are described and illustrated. Thismia domei, characterized by its perianth lobes that are upright and curve inward, but are imperfectly connate, falls within section Odoardoa. Thismia terengganuensis is characterized by its mitre with three appendages on its apex, so falls within section Geomitra. Both new species are unique and totally different from other described species, T. domei by the trichomes on its outer perianth tube surface and T. terengganuensis by its mitre with slender appendages. Thismia javanica J.J.Sm, also from Terengganu, is a new record for Peninsular Malaysia.
