Abstract

Ajai K. Singh

The main aim of the present study was to record morphological expressions and taxonomic significance in seedlings of Oroxylum indicum. Seedlings have been observed up to 5th leaf stage for 84 days from morpho-taxonomic view point. Seedling germination was Macaranga type. The morphological attributes found taxonomically significant are collet (with distinct ring), paracotyledon blade (anisocotylar, reniform, bilobed and deeply emarginated), glabrous hypocotyl and epicotyl and leaves simple up to 4th leaf stage, but compound afterwards.
