 patent 2 inches long 7-8 lines wide from an oblique trun- 

 cated base oblong acuminate subpinnatifid with the lobes 

 truncated obtuse or crenate, lowest one shortly petiolulate, 

 superior ones adnate at length confluent, costules standing 

 at an angle of 70°, veins at an angle of 20-25° 1-5 on each 

 side, lowest superior ones extending to a tooth in the sinus 

 of the lobes, inferior ones a little above the margin of the 

 sinus, sori contiguous to the costule almost reaching the 

 margin, lowest anterior ones diplazioid, involucre membra-

 justly, that the Anpl. radicans, Sw., is the same as our A. rhizophorum. If so, 

 the A. radicans of Schkuhr and Willdenow (for Willdenow quotes Schkuhr's 

 figure) is very different, and a diplazioid Fern. Yet both these authors refer to 

 Swartz as the author of their species. Schkuhr's plant is, however, represented 

 as a pinnate species, but not as " radicant" at the apex. Corresponding with this 

 figure I possess numerous specimens from tropical America (some pinnate, more 

 numerous ones bipinnate), which I am disposed to bring under this species. 

 These seem quite to correspond with the Aspl. duhium of Mettenius, whose 

 name I adopt.
