Revision of the pseudo-stipular species of Medinilla (Melastomataceae)
Blumea: Biodiversity, Evolution and Biogeography of Plants , Volume 46 - Issue 3 p. 527- 567
A revision is presented here of a group of mainly Papua New Guinea species of Medinilla Gaudich. ex DC. (Melastomataceae) peculiar for possessing a feature nearly unique for the family: leaf blades with a pair of lateral lobes at the base (‘pseudo-stipules’). This character was previously recorded for Astronidium miraculum-dei J.F. Maxwell & Veldk. (Astronioideae) from the nearby Solomon Islands. Various explanations, none satisfactory, for this phenomenon are explored. The group consists of 15 taxa, 2 previously described, 13 proposed here. The correct authorship of Medinilla is ‘Gaudich. ex DC.’, the correct name for the type species is Medinilla medinilliana (Gaudich.) Fosberg & Sachet, and not M. rosea Gaudich. ex DC., nom. superfl. Medinilla rubicunda (Jack) Blume var. hasseltii (Blume) Bakh.f. is validated. The descriptions of M. arfakensis Baker f. and M. brassii Markgr. are emended. A study of the palynology confirmed the homogeneity within Medinilla and among related genera.
