I have only seen this elegant plant once in flower, in 1816, in the Botanic Garden at Calcutta, where it was intro- 
duced from the mountains bordering on the district of Sillet, by the late Mr. M. R. Smith. It is possible that it may 
be the same species as my Ruellia urophylla, uumber 2344 of my Catalogue of the Herbariums of the Honourable East 
India Company; a point which will be decided in the Synopsis of the family of Acanthaceæ, from the able pen of 
Professor Nees Von Esenbeck, which will be found towards the end of the present volume.
