Muell.-Arg, 1863 (Euphorbiaceae), from the Andaman and Nicobar Islands, India; a data deficient species. Biodiversitas 16: 22-26. Excoecaria indica (Wild.) Muell.-Arg was recorded from Middle Andaman and Great Nicobar Island representing a newaddition to the mangrove flora of the, Andaman and Nicobar islands. This species is characterized by its thorny trunk, crenulatelanceolateleaves and cherry-sized green fruits containing three seeds. Information about E. indica is inadequate, and it is recognized asdata deficient species. Further studies and conservation measures are imperative for managing the mangrove diversity of the islands withregards to this species.

Abstract

Ragavan P, Ravichandran K, Mohan PM, Sxaena A, Prasanth R S, Jayaraj RSC, Saravanan S. 2014. New distributional records of Sonneratia spp. from Andaman and Nicobar Islands, India. Biodiversitas 15: 251-260. Sonneratia lanceolata, Sonneratia x urama andSonneratia x gulngai was collected from Great Nicobar Island, which representing a new addition to the mangrove flora of India. S.lanceolata is distinguished from S. caseolaris by its drooping branches, lanceolate leaves and ovoidal bud without medial constriction.S. x urama and S. x gulngai are putative hybrids. S. x urama is putative hybrid between S. alba and S. lanceolata, whereas S. x gulngai is putative hybrid between S. alba and S. caseolaris. A detailed description along with colour plate and relevant notes is provided for further collection and identification of these species in the field.
