996 CRYPTOGAMIA. FILICES. Polypodium 
P. Thelyp'teris. Leafits wing-cleft: lobes very entire, the under 
surface entirely covered by clusters of capsules.

Its habit like P. Filix-mas. Stem smooth. Old leafits covered with cap¬ 
sules. Barren leaves broader and blunter. Linn. Root small, creeping. 
Dicks. Wings deeply divided, but the divisions do not reach to the mid¬ 
rib. Lobes when in seed much contracted, and narrower than before the 
capsules are fully formed, but this circumstance is very general through 
the whole tribe. (The slender creeping root , and the crossing, but 
separate leafits , distinguish this species from every other. Sm. E.)

(P. crista'tum. Fronds pinnate: pinnae subcordate, oblong, pinna- 
tifid: the segments oblong, obtuse, dentato-serrate: stipes 
chaffy. E.) 
( Hook. FI. Lond. 113— E. Bot. 2125. E.) 
(Brands many from the same root, yellow green, one to two feet high, 
linearo-lanceolate, erect, rather rigid, nearly bipinnate. Stipes green, 
beneath dark purple, on the upper side channelled, smooth, every where 
chaffy, scales ovate, acute, membranous, pale brown. Pinnae upon the 
sterile fronds most approximate, upon the fertile ones more distant, all 
alternate, cordato-oblong, more or less attenuated, but obtuse at the 
apex, towards the middle three inches long, the inferior ones somewhat 
shorter, the superior ones gradually decreasing, and terminating in a 
short acuminated point. Rachis smooth. Pinnules or the segments of the 
pinnae, alternate, oblongo-ovate, obtuse, at the base confluent with the 
flexuose nerve, smooth, the inferior ones somewhat lobed, at the mar¬ 
gins irregularly and obtusely serrated, the rest have the margins inciso- 
serrate. Fructification dorsal, on the superior pinnae disposed in a double 
series between the margin and the nerve of the segments. Sori roundish. 
Indusium membranaceous, pale brown, almost white, between round 
and reniform, fixed at the sinus, the margins free. Capsides numerous, 
small, spherical, brown, upon long foot-stalks, reticulated, surrounded 
by an elastic, articulated, incomplete ring, bursting transversely. Seeds 
the soil greatly by their saline particles ; and thus Horace, though not without a moral 
inference, Lib. i. Sat. 3. 37, 
“ Neglectis urenda Filiv innascitur agris.” 
Scarcely any production of a tropical climate can present a more truly elegant appear¬ 
ance than does this and the sister Fern, of luxuriant growth, as fringing or feathering the 
high banks of the narrow lanes of South Devon. The Scotch term Bracken , (like Gowan,) 
we conceive to be rightly understood as generic, including several different plants, and 
thus it would seem to be almost indifferently applied both to our present species and Pier is 
aquilina* E.)
