POLLINATION ECOLOGY OF RHYNCHOSIA SUAVEOLENS (L.F.) DC. (FABACEAE), A PERENNIAL ERECT SHRUB IN THE SOUTHERN EASTERN GHATS, ANDHRA PRADESH, INDIA
Journal Title: Romanian Journal of Biology - Plant Biology - Year 2017, Vol 62, Issue 2
Abstract
Rhynchosia suaveolens is a perennial erect shrub. It flowers during October January with peak flowering during November. The flowers are hermaphroditic, nectariferous, self-compatible and have an explosive pollination mechanism adapted for pollination by bees. They do not fruit through autonomous selfing but fruit through manipulated selfing, geitonogamy and xenogamy mediated by pollen vectoring bees. Lycaenid butterflies also visit, especially during peak flowering season, but they principally act as nectar robbers. The flowers not visited by bees fall off while those visited and pollinated by them set fruit. Seed dispersal occurs by explosive pod dehiscence. Perennial root stock produces new foliage during rainy season. Seeds also germinate at the same time but their continued growth is subject to the availability of soil moisture content. Therefore, R. suaveolens expands its population size in areas where soil is sufficiently moist and also in areas where trees or woody shrubs provide shade. Since the plant is not widely distributed, its occurrence is almost unknown to locals and hence is not used for any purpose.
