1888.] H. F. Blanford— ^ List of the Ferns of Simla. 315 



fronds in June, and in September fertile fronds may be bunted for in 

 vain. 



97. OSMUNDA REGALIS, L. 



Very rare, and now nearly extirpated by assiduous collectors. 

 Below 6,000 ft. 



98. Ophioglossum vulgatum, L. 



Rare. Found by Dr. Watt on Hatu between 8,000 and 9,000 ft. 

 in July 1885. It has been found also at Mussoorie. 



99. BOTRYCHIUM LUNARIA, Swartz. 



Equally rare. Found with the preceding by the same botanist and 

 also on the slopes of Kumalhori near Nagkanda. 



100. BOTRYCHIUM DAUCTFOLItJM, Wall. 



Rare. I have found it only on one hill within the limits of Simla, 

 where it occurs, in glades in the forest, at an elevation a little below 

 7,000 ft. 



101. BOTRYCHIUM YiRGiNiANUM, L., var. lanuginosa, Wall. 



Rare, though less so than the preceding. I have gathered it at 

 several places round Simla at elevations between 5,000 ft. and 6,800 ft.
