POLYPODIUM (§ Drynaria) piverstroirum, Br. 
Diverse-leaved Polypody. 
Potypopium (Drynaria) diversifolium ; caudex stout, elongated, clothed with 
ferruginous, long-pointed scales ; fronds of two kinds collected together in 
a sort of coronal tuft; séevile ones a span. or more long, sessile, oblong- 
ovate, acuminate, caudate at the base, subpellucid, costate, tawny, lobato- 
pinnatifid; segments obtuse, ovate, the upper ones lanceolate ; fertile ones 
long-stipitate, two to four feet long, lanceolate, pinnate; pinne distant, 
a span to a foot long, linear-lanceolate, acuminate, subpetiolate, coriaceous, 
green, articulated upon the rachis, with a depression or obscure gland often 
at the inferior base, crenate ; sori sunk in the frond in two rows, one on 
each side the costa ; primary veins in the sterile fronds piunated, secondary 
ones strongly reticulated with angular, oblong areoles, having no free vein- 
lets ; fertile fronds, primary veins indistinctly pinnate, the rest irregularly 
anastomosing, with here and there free veinlets in the areoles.

M. Bory de St. Vincent, when he formed his genus ‘Drynaria, 
characterized it as having the fronds of two kinds (biform, not 
uniform), that is, having the sterile fronds short, broad, sessile, 
somewhat resembling a dried oak-leaf (whence the name, from 
Spus, an oak), whilst the fertile fronds are totally different, long- 
peticled and deeply pinnatifid or pinnated. Mr. J. Smith and 
Mr. Moore adopt the genus, retaining the above character, but 
including in it the Polypodium Heracleum, Kae. (Drynaria mor- 
billosa, J. Sm. and Moore), figured in our last number, Plate 1, 
and Polypodium coronans, Wall. These have perfectly uniform 
fronds, or, in other words, each frond seems to combine the two ; 
the base in texture and general form resembles the sterile fronds
