New Distributional Records of Three Rare Ferns from Odisha, India

Abstract

Niyamgiri and Kotgah Wildlife Sanctuary are part of the Eastern Ghats located at Odisha. The altitude range of these mountain ranges between 400–1516 m shows the diversity of vegetation due to their undulating mountain peaks, deep gorges, valleys and numerous springs. Three species viz., Amblovenatum opulentum (Kaulf.) J. P. Roux, Pronephrium articulatum (Houlston & T. Moore) Holttum and Sphaerostephanos hirtisorus (C. Chr.) Holttum (Family: Thelypteridaceae) collected from Niyamgiri hill and Kotgarh Wildlife Sanctuary are recorded for the first time from Odisha state. The same are documented here with taxonomic details and photographs of herbaria
