Abstract
Abstract: Flowers have evolved suites of traits that are associated with the attraction, reward and utilization of particular pollinator types. Specialization on particular pollinator functional group results in a particular combination of floral traits with consequences on plant fitness through efficient pollen delivery and pollen receipt at the population and species level. The aim of this study was to describe the floral morphology, nectar production patterns, floral visitors and natural fruit set in a population of Echeveria rosea Lindley (Crassulaceae) in central Veracruz, Mexico. The floral traits of Echeveria rosea correspond to the typical hummingbird pollination syndrome. The diurnal pattern of accumulated nectar (volume and amount of sugar) produced by the species corresponds to values reported for other hummingbird-pollinated species. Based on observations of foraging behavior, the Garnet-throated Hummingbird (Lamprolaima rhami) seems to be a more effective pollinator than the White-eared Hummi...
