Abstract :

The family Lamiaceae is well known for floral peculiarities and pollination syndromes. Here we are describing about another floral syndromes of Lamiaceae. The Clerodendron Paniculatum is commonly known as pagoda lilly. The plant is well known for its beautiful flower and it is also used for many medicative purposes. Detailed studies were carried out on the flowering phenology and pollination studies. The flowering phenology observed as June– October. The sunbird Nectariania zeylonica one of the regular visitor of the plant and flower produce nectar for visitors. The long narrow tubed corolla highly suited for narrow beaked sunbird. The correlation between beak length (17–18mm) and corolla tube (18–19mm) is pointed out here. The potential pollinator was identified as sunbird N. zeylonica. The interesting feature of our study is that, absence of bee visitation. In the eeding analysis shows that plant is a fully cross pollinated species. The self pollination ( Autogamy) was carried out around 20 flowers and self pollination resulted in 0% fruit set. Open pollination in natural conditions resulted in 73% fruit set. Flower bud bagged by removing stamens and stigma resulted no fruit set (Apomixis). Manual pollinations using pollen from other flowers of the same plant resulted in 60% fruit set. Manual cross pollinations using pollen from flowers of different plant resulted in 65% fruit set.
