Ilah. Toong Dong, mountains of Ava, WaUich. Mishniee, Griffith. — I have 

 received besides a young specimen of a Fern which I can liardly distinguish from 

 this, marked by Kunze " Allantodice up. ?, nunquam fcrtilis visa, Fort Natal, 

 Giiei7i:ius." The original plant I have only received from the two localities 

 above mentioned. It is a well-marked sjjecies, and may rank near Jspl. achillea:- 

 folium.
