Karyomorphological studies in three species of the genus Phlogacanthus Nees occurring in Assam

Abstract

The genus Phlogacanthus Nees belonging to the family Acanthaceae is an important ethnomedicinal genus of North Eastern part of India. The present study was undertaken to study the karyomorphology in the genus Phlogacanthus Nees comprising of three species of this taxon from Assam viz., Phlogacanthus thrysiflorus Nees, Phlogacanthus curviflorus (Wall.) Nees and Phlogacanthus jenkinsii C.B. Clarke. The amitotic preparations were done following the standard procedure for preparing of chromosomes. Cytotaxonomical features and karyomorphology were studied karyotype and counting of P. curviflorus and P. jenkinsii have been done.
