to figures.

There can, I think, be no doubt of this pretty Fern being 

 the Leptochilus Linncenus of Fee, 1. c. ; but he quotes Linnaeus' 

 Acrostichum lanceolatum, Amoen. Acad. 1. p. 268 ; though 

 it is quite clear that Linnaeus had quite another Fern in 

 view, since he says of it, in Sp. Plant p. 1523, " fructificationes 

 sunt puncta confertissima, versus apicem frondis," and he refers 

 to Hort. Malab. 12. t. 27. But Swartz, long ago, showed 

 that the Linna3an plant was the Poly-podium acrosiiclioides of 

 Forst. Prodr. now generally referred to Niphobolus. 



Fee afterwards in his Genera Filicum refers Linnaeus' Acros- 

 tichum lanceolatum to Dendroglossa ; while Moore places it 

 in his Gymnopteris, among the Pleurogrammeee.
