Main Article Content
Hopea glabra Wight & Arn. and Hopea utilis (Bedd.) Bole are two little-known highly threatened endemic dipterocarps distributed in evergreen forests of the Western Ghats.Â Although literature surveys and herbarium records show occurrence of these species in different forest areas of Kerala, the present study could locate Hopea glabra from the Silent Valley National Park and Hopea utilis from Shankili forests in Kulathupuza range, enabling the portrayal of current distribution, basic ecology covering phenology, species association, regeneration and conservation status along with taxonomic notes.
