Willdenow’s Polypody. 
Potypopium (§ Drynaria) Willdenowii ; caudex long, very stout, repent, densely 
clothed with lanceolato-subulate, delicate, membranaceous scales, fringed 
with long, silky, golden hairs ; fronds of two kinds, forming a coronal tuft ; 
sterile ones four to six inches and more long, sessile, ovate, firm, strongly 
costate, scarioso-membranaceous, subcoriaceous, more or less deeply pin- 
natifid, cordate at the base, strongly and prominently veined ; fertile fronds 
long-stipitate (stipes and rachis beneath dark-purple), one and a half to two 
feet long, herbaceous, oblong-ovate, deeply almost to the rachis pinnatifid ; 
segments a span or more long, linear-oblong, entire or serrated only at the 
moderately acute apex, lowest ones distant and decurrent; veins in the 
sterile fronds having the primary ones very distinct and pinnate, secondary 
and tertiary ones with no free veinlets; in the fertile fronds the primary 
veins are indistinctly pinnate, the rest anastomosing, with here and there 
free veinlets in the areoles; sori prominent, tawny, in two rows, situated 
close to the costa.

We have here another species of that fine group of Poly- 
podium to which the name of Drynaria has been given, having 
two distinct fronds; the sterile almost resembling a withered 
oak-leaf, of which we have offered an example at our Plate 5 of 
this work, Polypodium (§ Drynaria) diversifolium. Dr. Wal- 
lich named the present species P. propinguum in his Herbarium 
and in his ‘ Catalogue,’ probably from its affinity with P. querci- 
folium, L. From that species it is at once distinguished by having
