 Select, of Kaempfer : and the latter figure sufficiently corresponds.

This exactly agrees with the figure above given by Fee, of Hetero- 

 neuron proliferum : nor does it appear that Cyrtogonium sinuosum, of 



J. Smith, is different. 



1. Gymnopteris decurrens, Hook. ; fronde sterili ampla submembrana- 

 cea nitida pinnata, pinnis subquinque ovali-lanceolatis longe tenui- 

 acuminatis obscure sinuatis basi decurrentibus tribus superioribus 

 coadunatis terrainali maxima, fertili multo minore rigidiore, pinnis 

 angustioribus vix acuminatis repando-sinuatis, stipite elongato rachi- 



busque castaneis nitidissimis.

I do not find any species of Gymnopteris, to which genus or group 

 of Acrostichum this belongs, which accords with this. Its nearest affi- 

 nity unless it can be the normal or perfect state of G. subsimplex, of 



Fee, Acrostich. t. 40. f. iii., G. subrepanda ?, J. Sm., the only oriental 

 species of the genus— is with the G. nicotianafolia, Pr., and G. semi- 

 pinnatifida, Pee, but they are South American species, and very dis- 

 tinct. All that I have seen of this plant are, a very good sterile, and 

 an equally good fertile, frond, in Dr. Harland's collection. The former 

 (sterile frond) is rather more than 1£ foot long and 14 inches broad, 

 divided into five pinnae, of which the lateral ones are nearly opposite, 

 8-9 inches long ; the terminal one 14 inches long, all oval- or broad- 

 lanceolate, tapering into a long, narrow point, subsinuate at the mar- 

 gin, the bases decurrent, the three upper ones very much so, and coad- 

 unate ; the two lowest remote from the rest, and much less decurrent. 

 Venation conspicuous ; primary veins parallel, oblique, nearly straight ; 

 veinlets copiously reticulated with free veins in the areoles (areolae ap- 



ram 



pendiculata?). Stipes stout, and rachises also sioui. aim P 



the under side, dark chestnut-brown, very glossy, Fertile frond exactly
