Monographs Details: Macrocentrum neblinae Wurdack
Authority: Maguire, Bassett & Wurdack, John J. 1964. The botany of the Guayana Highland--Part V. Mem. New York Bot. Gard. 10: 1-278.
Family:Melastomataceae
Discussion:In a geographic reversal of the above-cited discovery of M. droseroides, M. neblinae was recently collected by the Oxford 1959 British Guiana expedition in the Potaro River Valley (No. 145). The leaf blades in the eastern material are slightly more elliptic than in the Neblina collections, but otherwise there is no obvious differentiation. Both the above-cited examples show that some species of Macrocentrum are much more extensively distributed than previously indicated. The best-collected of the widespread species is M . glandulosum Gleason, known from the western Venezuelan sandstone area eastward to Cerros Venamo and Uei (Steyermark & Nilsson 317, 445) in extreme southeastern Estado Bolivar (and certainly to be expected on the Kaieteur Plateau in British Guiana).
