Divya S Pillai, AK Sreekala
Syzygium myhendrae (family: Myrtaceae) is a semi evergreen, endangered tree growing in parts of Western Ghats. The present investigation was aimed at understanding its phenology, floral biology, and pollination biology. The pollination biology was assessed through observations on the frequency of pollinators visit and also from the floral characters. The flowering period of mature individuals was reported to be from June – November and fruit set in December. The tree usually flowers at the onset of south west monsoon and the peak bloom was noticed during September. Honey bees which include A. cerana, A. dorsata and Trigona iridipennis are the prime pollinators. Not only honeybees but also butterflies, moths, and flies are visiting the flowers during the peak period of flowering. Diurnal anthesis, numerous stamens soft and bright inflorescence are the major pollination syndromes for pollinators. The fruit is edible and very small with only 1-2mm thickness of fruit pulp. The single seeded fruit becomes edible after 18-34 days. The common frugivores include birds and bonnet monkey.
