Nectar is one of the most important flower traits, shaping plant–pollinator interactions and
reproductive success. Despite Orchidaceae including numerous nectariferous species …

Pollination of the pantropical Vanilla has been linked to melittophily and food deception.
Here we investigated the role of flower traits on the reproduction of Neotropical Vanilla. We …

Colleters are trichomes or emergencies that produce a sticky exudate consisting of a mixture
of mucilage, lipids, terpenes, and phenolic compounds. Colleters occur in at least 60 …

Pleurothallidinae orchids have been the focus of many multidisciplinary studies due to their
challenging systematics and taxonomy. The synapomorphies already recognized in the …

Phylogenetic relationships and osmophore evolution of six Cirrhaea spp. were studied.
Floral morphology was analysed using fresh flowers, and osmophore anatomy was …

Relationships among floral biology, floral micromorphology and pollinator behaviour in bird‐
pollinated orchids are important issues to understand the evolution of the huge flower …

Members of Oncidiinae are widely known for their interactions with oil-collecting bees that
explore lipophilic secretions on flowers. They may also be pollinated through food deception …

Orchidaceae is one of the largest angiosperm families. Although extensively studied, reports
of anatomy of secretory structures of orchids are relatively scarce. Rodriguezia venusta is an …

Epidendrum, the largest genus of Neotropical orchids, contains both nectar-secreting and
nectarless species. Here, we compare the fine structure of the inner floral spur, termed the …

Ornithophily has evolved in parallel several times during evolution of angiosperms. Bird
pollination is reported for 65 families, including Bromeliaceae. One of the most diverse …
