MELO, Gladys Flávia; MACHADO, Isabel Cristina  and  LUCENO, Modesto. Reprodución de tres especies de Clidemia (Melastomataceae) en Brasil. Rev. biol. trop [online]. 1999, vol.47, n.3, pp.359-363. ISSN 0034-7744.

We compared the reproductive systems in populations of Clidemia capitellata (Bonpl.) D. Don, C. bullosa DC. and C. hirta (L.) D. Don. (Melastomataceae). The three species occur in small populations in forest margins at Mata de Dois Irmos, Recife, Pernambuco, Brasil and are sympatric. They flower throughout the year, and are occasionaly visited by Halictidae bees, Augochloropsis sp.; the bees collect pollen by vibration ("buzz pollination"). The three species are agamospermous and exhibit a high level of male sterility, as measured by their low pollen viability.

Keywords : "Buzz pollination"; agamospermy; hibridization; Melastomataceae.
