Malayan region to the Seychelles. 
It is impossible for me to follow Christ(yn sen's Index in treating this species 
as D. unita and renewing the confusion that has exsisted for a long time regarding 
Nephrodium unilum R. Br. {■=-Bryopteris yongylodes). BJunie's name is here 
accepted for tlw^ species. There is a limit even to the virtues of priority !

No. 279 Cuming ^^Nephrodiu-)n mucronatum J. Sm," appears to differ from this 
species in its pinna; being mc*e strongly hastate at the base and in being more 
strongly villous. Dryopteris arida of the Philippines is usually more strongly 
villous and the pinnce are shorter and more distant than in the form found in 
India (Dehra Dun, leg. Stanford) .

A specimen from Baguio, Province of Benguet, Luzon (5108 Curran) August,

hispidula.
