Muthu ji The plant at FOI is perhaps wrongly identified as A. spinosus A. mollis has leaves less deeply divided without spinose teeth, bracts and calyx teeth are are not spinose, calyx lobes hairy along margin
In both A. montanus and A. spinosus (syn: A. spinosissimus) the leaf lobes and bracts are spinose. In A. montanus leaves are glossy green above, less deeply pinnatifid; In A. spinosus the leaves are rigid, leathery, deeply pinnatifid with rigid spinose teeth. http://www.desert-tropicals.com/Plants/Acanthaceae/Acanthus_spinosus.html http://davesgarden.com/guides/pf/showimage/209106/ Obviously both your plant as one on FOI is A. montanus http://www.botany.com/acanthus.html Needless to say that there is terrible mix up of photographs on the internet. -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
