A rare and endemic variety of Trigonostemon viridissimus (Kurz) Airy Shaw is re-collected after 70 years from South Garo Hills district of Meghalaya, India. The field assessment ascertained that the occurrence and population status of this endemic taxon is very rare and low due to continuous decline in area of occupancy for habitat loss as because of various anthropogenic interferences such as primitive method of shifting cultivation called “Jhum cultivation” or “slash-and-burn cultivation”, mining activities, over exploitation of natural resources in the state of Meghalaya. For conservation perception IUCN status of the taxon has been evaluated and a detailed taxonomic description along with photographic illustration is given for easy identification.
