Abstract
A new species, Mitrephoramonocarpa R.M.K.Saunders & Chalermglin, sp. nov. (Annonaceae), is described from Surat Thani Province in Peninsular Thailand. It resembles two other species, M.alba Ridl. and M.keithii Ridl., with which it is broadly sympatric, but can be distinguished by its solitary flowers (not borne in thyrsoid inflorescences as in most other Mitrephora species), single carpel per flower (and hence single monocarp per fruit) and the lack of a monocarp stipe. A key to the nine Mitrephora species in Thailand is provided.
Highlights
There are currently eight Mitrephora species recorded from Thailand (Weerasooriya and Saunders 2010), viz. M. alba Ridl., M. keithii Ridl., M. sirikitiae Weeras., Chalermglin & R.M.K.Saunders, M. teysmannii Scheff., M. tomentosa Hook.f. & Thomson, M. vulpina C.E.C.Fisch., M. wangii Hu and M. winitii Craib
A new species similar to M. alba and M. keithii, but distinguished by its solitary flowers that are not borne in an inflorescence, its single carpel per flower and single sessile monocarp per fruit
The phylogenetic affinities of M. monocarpa are currently unknown, morphologically it resembles two species, M. alba and M. keithii, with which it is broadly sympatric in Peninsular Thailand: all three species have a sparsely hairy indument on the twigs and leaves and comparatively small flowers
