Obs. — This fern has hitherto been placed in the tribe Ac- 

 rostichieee, and Presl has characterized it as a distinct genus, 

 differing from Pobjhotrya by its anastomosing venules ; but 

 on examining the specimens bearing the above numbers, it 

 appears evident that all previous descriptions and figures of 

 the fertile frond have been taken from starved or imperfectly 

 developed plants, as exhibited by those numbered 295, and 

 341, which are characteristic of the tribe Acrostichiea, where- 

 as Nos. 302 and 321, are evidently the same in a mere per- 

 fect state, the fertile fronds being but slightly contracted, and 

 bearing round or oblong sori, and therefore characteristic of 

 the tribe Polypodies. In some cases the venation of the fer- 

 tile frond is free and bearing round sori, therefore not differ- 

 ing from that of Polypodium ; but it is usual for the lower 

 venules to anastomose, (as in the sterile frond,) and produce 

 round or oblong sori, presenting some affinity with Meniscium 

 and Goniopteris.
