Flowering phenology and floral success in Barleria involucrata var elata (Acanthaceae).
MetadataShow full item record
The flowering phenology and floral success or the monocarpic understorey shrub species Barleria involucrata var. elata (Acanthaceae) in a medium elevation evergreen forest in southern Western Ghats was examined. No proximate environmental cues could be identified in this study for flowering initiation. Peak flowering was observed in December. Floral predation was low and predators tracked floral availability. Early flowering Individuals suffered greater floral predation. Floral success was influenced by floral display. visitation rates and pollen load deposited on stigmas. With the onset of synchronous flowering, decreased floral predation and increased fruit set was observed. Plant size influenced the relative reproductive success of individuals.
