POLYPODIUM (§ Drynaria) Heracizum, Kze. 
Hogweed-leaved Polypody. 
Potyropium (Drynaria) Heraclewm ; caudex stout, repent, densely clothed with 
very long, slender, silky, subulate, exceedingly acuminated, bright tawny 
scales; fronds three to four and more feet long, oblong-lyrate, ‘elongated, 
coriaceous, acuminate, the base sessile, broad, subcordiform, and subpellucid, 
and moderately sinuato-lobate; above this, in the contracted portion, be- 
coming regularly pinnatifid, widening upwards, where the segments are a 
foot or a foot and a half long, three to four inches broad, oblong acuminate, 
everywhere glabrous; midrib of the segments stout, primary lateral veins 
pinnated, secondary ones transverse, nearly equidistant, curved, forming 
oblong areoles filled up with anastomosing veins, which have subquadran- 
gular areoles and free veinlets; all the veins prominent beneath; sori very 
copious, in two rows within each primary transverse areole and almost always 
terminating a short free veinlet, rarély seen upon the union of two or more 
veinlets.

We spoke of this plant in our volume of ‘ Exotic Ferns,’ under 
tab. xci., Polypodium (Drynaria) coronans, Wall., the near ally of 
that almost equally magnificent species, as the P. morbellosum of 
Presl, the name by which we received the living plant from the 
Dutch gardens ;: but a slight comparison of the venation and 
position of the sori here and in the figure of P. mordillosum as 
given by Presl in his ‘ Reliquiae Henkeanz’ will satisfy any one 
that the two are far from being identical. Both, according to 
Mettenius, are in cultivation in the German gardens, but the 
true morbillosum is quite unknown to us. 
Like the P. coronans, the ample fronds form a splendid crown 
to the thick creeping caudex, which latter is densely clothed with 
rich golden-tawny, long, subulate, membranaceous scales ; that 
of P. coronans has scales of the same colour indeed, but broader, 
strongly reticulated, and quite villous. Though the general form
