A. small fern resembling the British Adder’s Tongue (Ophioglosstim vulgatum L.), but 
much smaller in all its parts. Each frond consists of a small leaf-like part and a two-ranked 
spike of sporangia which is borne on a longish stalk. We saw old women at Dibrugarh 
gathering this plant from amongst grass at the side of the Red Road. They said that they 
used it as a sag. The plant is difficult to find, but when once fonnd, is easily distinguished.
