Abstract
Specialized glands that produce and store floral oil are found in 11 families of flowering plants, with greater representation in Malpighiaceae. Solitary bees use this resource to feed larvae and for cell lining. Oil interactions have been reported mainly at the population level and in some community studies that have commonly ignored not only the fewer representative families of oil-offering flowers, but also the floral visitors that do not collect floral oil. We have compiled and examined the interactions between oil-offering flowers and floral visitors in world biomes, to describe the structural patterns of the oil interaction meta-network and evaluate the species' functional roles. We reviewed 169 studies, which mainly used a phytocentric approach, reporting 1460 interactions between 214 species of oil-offering flowers and 377 species of floral visitors. Malpighiaceae and bees (mainly oil-collecting bees) were the most frequently investigated. The meta-network of oil interactions showed a modular structure, mainly influenced by botanical families, and core–periphery organization. The most important functional roles were associated with Malpighiaceae and oil-collecting bees, possibly due to their representativeness and geographic distribution.

Abstract
PREMISE There is little direct evidence linking floral development and pollination biology in plants. We characterize both aspects in plain and ornamented flowers of Trimezieae (Iridaceae) to investigate how changes in floral ontogeny may affect their interactions with pollinators through time. METHODS We examined floral ontogeny in 11 species and documented pollination biology in five species displaying a wide range of floral morphologies. We coded and reconstructed ancestral states of flower types over the tribal phylogeny to estimate the frequency of transition between different floral types. RESULTS All Trimezieae flowers are similar in early floral development, but ornamented flowers have additional ontogenetic steps compared with plain flowers, indicating heterochrony. Ornamented flowers have a hinge pollination mechanism (newly described here) and attract more pollinator guilds, while plain flowers offer less variety of resources for a shorter time. Although the ornamented condition is plesiomorphic in this clade, shifts to plain flowers have occurred frequently and abruptly during the past 5 million years, with some subsequent reversals. CONCLUSIONS Heterochrony has resulted in labile morphological changes during flower evolution in Trimezieae. Counterintuitively, species with plain flowers, which are endemic to the campo rupestre, are derived within the tribe and show a higher specialization than the ornamented species, with the former being visited by pollen-collecting bees only.
