300 H. F. Blanford— ^ List of the Ferns of Simla. [No. 4, 



cuneate to rhomboidal and transversely elliptical, being broader than 

 deep. Both series of forms occur throughout the range. The sori are 

 generally orbicular reniform with a deeply notched margin ; but some- 

 times oblong with a straight margin. 



13. Adiantum pedatum, L. 



Rare. I have found it only on the north face of Hatu, at elevations 

 of 8,500 and 10,000 ft. This last is nearly 1,000 ft. higher than Clarie's 

 and Beddome's highest assigned range. 



14. Cheilanthes subyillosa, Hook. 



Chiefly above 8,000 ft. But I have found stragglers as low as 7,300 

 ft. on Jako. It is common in the neighbourhood of Matiana and 

 Nagkanda, on the bank by the roadside. 



15. Cheilanthes Dalhousi^e, Hook. 



Quite distinct from 0. farinosa, and subject to little variation. Its 

 range is from 7,800 ft. to the highest visited (10,500 ft.). Fine speci- 

 mens are to be found on Jako, though not common. It is more abundant 

 on Kumalhori and Hatu. 



It appears to be restricted to the Himalaya, and is most abundant 

 in the N. W. Himalaya. In Sikkim it appears to be rare, but Sir J. 

 Hooker gathered it at 10,000 ft. on Lacheely, and Mr. Levinge found it 

 growing plentifully on Sinchal close to Darjiling at 8,000 ft. He agrees 

 with me as to its specific value. The following is a description of its 

 distinctive characters. 



Stipes 2 to 4 ins. long, shorter than the frond, naked or with a few 

 lax spreading scales near the base. Fronds 6 to 9 inches long, 2 to 4 

 inches broad, acute lanceolate, without white powder at any stage of 

 growth. Lower two pairs of pinnae subequal. Segments narrow. Lines 

 of sori interrupted at the sinus. Involucres even, crenate or toothed on 

 the margin, hardly lacerate. 



16. Cheilantbes albo-marginata, C. B. Clarke. 

 Very abundant in and around Simla, covering the roadside banks 

 and old stone retaining walls. Range from 4,800 ft. (my lowest) up to 

 8,500 ft., above which it is replaced by Gh. Dalhousice. Like that species 

 it appears to be restricted to the Himalaya and chiefly to the N. W. 

 Himalaya, though I learn from Mr. Levinge that his native collector 

 brought him a specimen from the interior of Sikkim. A Cheilanthes 

 which occurs on the Khasi hills, also Mount Abu and the Nilgiris, and
