Jangid, Prem Prakash; Gupta, SangeetaThe present paper provides comprehensive wood anatomical survey of 11 Indian species belonging to four genera of the subfamily Antidesmatoideae (Phyllanthaceae). Wood microstructure of the subfamily was found to be heterogeneous to a certain extent reflecting upon unnatural classification of the subfamily. Wood anatomy of Aporosa and Baccaurea was remarkably similar and they lack distinguishing wood anatomical characters. Systematic relationships evaluated within subfamily on wood anatomical context. The present systematic wood anatomical study did not corroborate with recent morphological and molecular phylogenetic circumscriptions. Antidesma showed adaptation to xeric environment and Aporosa and Baccaurea showed adaptation to mesic environment. Evolutionary wood anatomical study revealed that Antidesma and Bischofia are advance while Aporosa and Baccaurea are primitive genera in the subfamily.
