206 CHAEACTEES OF TEIBES AND GEKEEA. 



tinguisli it from Asindiitm. Setting- aside its simple 

 anastomosed venation, and viewing it in its general aspect 

 only, it appears to be related to Lastrea villosa, than which, 

 however, it assumes a more aboreous character. Its most 

 natural affinity is with Aspidmm macrodontum and A. gigan- 

 ieum. It is a native of India,, Malay, Philippine, Fiji, and 

 other islands. 



Sp. P. Leuzeana, Presl, Bedd. P. Brit. Ind., pi. 134. 



Obs. — In the "Species Filicum" fom- species are placed 

 under the section Pleoc?iemia of Nei^hrodium, two of which 

 possess no natural relationship with P. Leuzeana ; and I am 

 inclined to consider the fourth species, N. {Pleooiemin) 

 excellens identical with the original species, though Presl 

 makes a distinct genus of it (Proferea).
