Abstract

Tarenna asiatica flowers throughout the year with profuse flowering during december-april. the flowers are hermaphroditic, self- and cross-compatible, protandrous, nectariferous and entomophilous. the mating system is facultatively xenogamous with highest fruit set in xenogamy. The protandry facilitates autonomous selfing. Bees and butterflies effect both self- and cross-pollinations. Fruits mature within a short period and the fallen seeds germinate following monsoon rains in June-July. a dearth of floral resources exists during december-april period; T. asiatica with profuse flowering during this period plays a key role to provide pollen and nectar for the probing flower foragers and hence is considered to be a keystone species in the eastern Ghats forest
