Polypodium — Polypody. Hexacjonopterum — Six-angled- winged. 



The Polypodium Jiexagonopterum, must be considered as one 

 of the rare cultivated species. In appearance it somewhat re- 

 sembles our British P, Rohertianum and P. dryopteris. It is a 

 desirable species, from its being a hardy Fern, and no collection 

 should be without it; although even some of our larger col- 

 lections have it amongst their desiderata. 



A handsome, deciduous, hardy Fern. 



A native of North America. 



Introduced into England about the year 1811. 



The fronds are of a triangular form, bipinnatifid, pinnae op- 

 posite, sessile, decurrent at the base, the segments crenulatc, 

 oblong obtuse. Fronds lateral, hairy, adherent to a creeping 

 rhizoma.
