1888.] H. F. Blauford— J. List of tie Ferns of Simla. 311 



68. Nephrodium (Lastrea) crenatum, C. B. Clarke. 



Clarke and Beddome assign to this species a range from 2,000 up to 

 7,000 ft. in the Himalaya. It is nowhere common within the limits here 

 adopted. I have met with it as high as 7,500 ft. ; otherwise only at the 

 lowest levels visited. It is, however, common lower down on the hills 

 between 3,000 and 4,000 ft. as in the Jumna valley, and below Chakrata, 

 always growing in rock crevices. 



69. Nephrodium (Lastrea) Boryanum, Hk. and Bk. 

 Not uncommon in well shaded ravines below 6,000 ft. 



70. Neprodium parasiticum, L. 



Not met with above 5,000 ft. ; but common in the deep valleys at 

 4,500 ft. and below. It is a glabrous form, producing fronds up to 3 

 ft. long. 



71. Nephrodium pennigerum. Hook., var. muUilineata, Clarke. 



Mr. Clarke does not include the N.-W. Himalaya in the range of 

 this species. It occurs, however, together with the preceding at the 

 lowest levels visited below Simla, and I have it also from Mussoorie 

 collected by Mr. C. W. Hope, and from below Chakrata. 



72. Oleandra Wallichii, Presl. 



Not common, but locally abundant, growing on perpendicular rock 

 faces between 5,500 and 6,000 ft. 



73. PoLYPODiUM (Phegopteris) erubescens. Wall. 



On steep shady banks by streams at the bottom of some of the deep 

 valleys below Simla, where it is pretty common. My highest elevation 

 is about 5,500 ft. 



74. PoLYPODTUM (Phegopteris) aueiculatum, "Wall. 



Very rare in the neighbourhood of Simla. I have met with it but 

 once, viz., in 1882 in the Samal valley at 4,500 ft. 



75. Polypodium (Phegopteris) distans, Don. 



Common in ravines, down to my lowest level, and up to nearly 

 10,000 ft. At the former limit the fronds are small and narrow, with 

 short, distant pinn^ and the root stock decumbent, hardly creeping.
