Ferns of British India and Ceylon. 23 



Yar. multisectum. Very distinct as the extreme forms of 

 this appear, Dr. Watt has supplied me with a very complete 

 series, graduating from the most simple form of japonicum to the 

 finest cut multisectum ; the latter is very common about Simla, 

 6.000-9,000 feet alt. 



1. Cryptogramme crispa. Gathered by Prain in the crater 

 on Barren Island, Andamans. 

 (Also in Afghanistan.) 



3. Pell.ea tamburii. Omit this species ; it is a synonym 

 of Cheilanthes argentea. 



1. Pteris longifolia. Perak. (Day, Scortechim.) 



2. Pteris cretica. Perak. 

 6. Pteris ensiformis. 



Yar. /3 Grevilleana. This is probably only a variety of 

 Grevilleana No. n, as suspected byMettenius. Specimens at Kew 

 collected by Bishop Hose in Borneo have the fronds of both on 

 the same root. I have not seen the digitate fronds on any of the 

 N. Indian examples. 



10. Pteris quadriaurita. 



Yar. setigera. The oldest name for this is Pteris hamulosa. 

 (Wallich) ; it should be Pteris quadri-aurita var. hamulosa. 

 {Wall.) 



Var. 1 subquinata. (Wall.) A small form, 8-10 inches high ; 

 stipes stramineous ; fronds short deltoid, lateral pinnae often only 

 1-2, rarely 3-4 pair, with a large terminal central pinna, segments 

 long, nearly equally broad throughout, spreading at right angles 

 from the midrib, lower basal segments of the lower pinnae only 

 slightly enlarged and pinnatifid, or quite entire and uniform with 

 the others.

 and Winter botham) , Lachen Valley (Levinge). Mr. Levinge's
