Perak : Gunong Kerbau at 4,200 ft. (nat. cofl. F.M.S. 

 Mus.) . 



This elegant little fern is allied to L. calcarata and 

 especially to the form ciliata but differs in the indumentum, 

 the shortly cut lobes and the distinctly coriaceous texture 

 of the pinnae. The whole frond is much more narrow than 

 in any form of L. calcarata.
