Abstract

The present study reports the invasive occurrence of Ruellia elegans Poir. from northeastern India. The beautiful red flowered species flourishing in Digboi, Assam is marked as its new distribution extension. The occurrence has been documented as a new distribution record for the flora of Assam as well as northeastern India. A detailed morphological depiction, photographic images, characterization and taxonomic notes have been provided to aid in its identification and recognition.
