THE FERNS OF NORTH-WESTERN INDIA, 31 
[I have struck out of this list Davailia pulchra, Don, as I find that the 
common low-level, arboreal fern I and other collectors have been 
calling by that name is D. psealocystopteris, viz.—No. 4, infra. 1 do 
not think D. pulcira grows to the westward of Nepal, though it 
seems to be very commion in the N.-E. Himalaya and Assam (in the 
Khasi Hills at least), and on the Western Mts..in 8, India, and also in 
Tenasserim and Ceylon. |

The plant from the localities enumerated above is the common low-level 
arboreal Davallia. Specimens differ from each other in texture and cutting, 
correspondingly, perhaps, to the age and degree of fertility of the plant; but 
I do not think any of them are D. cherophylia, Wall., wnich has been assumed 
to be L. pulchra, Don (au older name), and which is common from Nepal east- 
ward to Assam and Burma, and in South India and Central Ceylon. I have 
had great ditheulty in determining what this plant is, but probably it is 
Kunze’s plans, which, there are reasons to believe, was collected in the Simla 
Region. His description, which I have quoted above, is defective in that he 
could say nothing about the rhizome ; and I cannot see that the indusium (in 
my material) is large, as he said it was, bug it appears on young and undamag- 
ed specimens “ovate, acute, membranaceous.” As J found that no type speci- 
mens of Kunze’s plant Sistedht in the Kew or British Museum Herbaria, I
