| ABSTRACT Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors, including native bees and the honeybee, on the pollination of a generalist rupestrian grassland daisy, Aspilia jolyana (Asteraceae), in Serra do Cipó, Espinhaço Mountain Range, Brazil. We recorded floral visitors and measured the seed set resulting from one single visitation. We observed a total of 442 visits, mostly by bees, with Bombus pauloensis and Apis mellifera being the most common floral... |

| Copaifera langsdorffii Desf. é uma espécie da família Leguminosae, subfamília Caesalpinioideae, de ampla distribuição no Brasil. O estudo da biologia reprodutiva desta espécie foi realizado numa área de cerradão aberto para pastagem da Fazenda Capim Branco, Uberlândia, MG. A espécie floresce durante o período das chuvas e dispersa suas sementes na época seca. As flores são branco-esverdeadas, com cerca de 0,5 cm de diâmetro, fracamente zigomorfas e estão reunidas em inflorescência paniculada. Apresentam um forte odor adocicado e duram apenas um dia. A antese inicia-se por volta das 5:00 h. Os recursos oferecidos aos visitantes são pólen e néctar. Produzem pouco néctar (0,2 ml) com concentração média de 49% de equivalentes de sacarose. Os visitantes mais... |

| ABSTRACT This study describes the floral phenology and morphology, reproductive biology and pollinators for eight legume tree species, Schizolobium parahyba, Senna macranthera, and Senna multijuga (Caesalpinioideae), as well as Andira fraxinifolia, Lonchocarpus cultratus, Pterocarpus violaceus, Swartzia oblata, and S. simplex (Papilionoideae), in the Atlantic Forest in Southeast Brazil. All the studied species showed an annual flowering pattern, and almost all are of the cornucopia-flowering type, with the only exception being Swartzia oblata, which was of the steady-state type. In general, the legume flowers studied are conspicuous, mostly medium-sized, and offer nectar and/or pollen as a resource. Self-incompatibility associated with the production of... |
