Neither nectar nor deception: the role of floral rewards in the pollination system of Laelia (Orchidaceae: Laeliinae).

Orchids offer a variety of floral rewards to pollinators. In many orchid groups, however, the transfer of pollen is based on food-deception, as in the case of Laelia (including Schomburgkia s.s.

Specialized seed dispersal in Neotropical Vanilla reveals fruit unpalatability to omnivores.

Flowering plants are essentially sessile organisms that disperse their genes through pollination, expanding their areas of occurrence through seed dispersal. In orchids, seed dispersal is commonly mediated by air currents. Conversely, members of several genera have evolved seeds adapted to endozoochory.

Nectar-mediated avian pollination in Cattleya (Orchidaceae: Laeliinae).

Orchids are notable for the variety of rewards produced for their pollinators. Nevertheless, many species are rewardless and pollinated by food-deceptive strategies. This is the case for Cattleya, a Neotropical genus of more than 100 species supposedly pollinated by food-deception.

A new remarkable Mill. (Orchidaceae) species endemic to the Espinhaço Range, Brazil: its phylogenetic position and evolutionary relationships among Neotropical congeners.

During surveys conducted on Neotropical , a new endemic species was found in the Brazilian campos rupestres of the Espinhaço Range. Here, this new remarkable species, namely Pansarin & E.L.

Non-species-specific pollen transfer and double-reward production in euglossine-pollinated Vanilla.

Commonly attributed to orchids, the pollen movement in Vanilla has been associated with food deception and specific plant-pollinator relationships. This study investigated the role of flower rewards and pollinator specificity in the pollen transfer of a widely distributed member to the euglossinophilous Vanilla clade, V. pompona Schiede using data collected from Brazilian populations.
