almost sub-laciniate or pinnatifid-serrate, the most prominent teeth or 
laciniations usually bearing a minute hard white recurved tooth (sometimes 
two) on their tips; colour pale greyish-green; upper and largest pinne 
broadly linear-oblong, very obtuse and truncate, 6-8 lines long, 3-4 lines 
broad, suberect, confluent at top, terminal lobe deltoid very obtuse; lower 
pinne occupying considerably more than half of the frond, much smaller than 
upper, orbicular and gradually decreasing in size downwards ; fertile fronds 
longer than barren ones, but more slender with fewer and more distant 
pinne ; pinne opposite and alternate, distant, ligulate, largest 1 inch long, 
1 line broad, apiculate, upper and larger ones slightly petiolate, terminal 
one subcaudate, lower ones excessively small; involucre finely reticulated, 
margins entire; scales on stipes 2 lines long, flat, deltoid-linear acuminate, 
nerved longitudinally and much dilated at base. Veins conspicuous, simple 
and forked, extending quite to margin, clavate, very few and distant, 
usually only 4-jugate in the largest pinne, the lowermost one or two pairs 
not springing from the midrib (this character is also found in the smallest 
orbicular pinne), midrib usually forked at apex.

Obs. I.—A species having close affinity with L. lanceolata and mem- 
branacea, particularly the latter, but differing in several important par- 
ticulars :—e.g., in its large normal sterile pinne being fewer in number and 
decurrent, and much more coarsely serrate, and fewer veined, with veins 
extending to margins and the lowermost not springing from the midrib ; in 
its small orbicular and deeply crenate-serrate pinne occupying nearly two- 
thirds of the frond; and in all being more distant from each other on the 
rhachis; and in its upper fertile pinns being petiolate, and their involucres 
finely reticulate with entire margins. 
Obs. I.—I have had several fully fronded plants containing together 
more than fifty specimens of barren and fertile fronds to look over, and 
their uniformity in habit and character is great; the plants differing only 
in size. 
Genus 22. Polypodium, Linn. 
Polypodium rufobarbatum, sp. nov. 
Plant terrestrial, sub-erect, wholly covered with long and stout red and 
shining jointed and moniliform hairs; rhizome creeping, densely hairy ; 
fronds 4-1 inch distant on rhizome. Stipes 1-8 inches long, and rhachis, 
slender, subflexuose, dry, channelled above, red, shining; frond 4-6 inches 
long, sublinear-ovate, acuminate, bipinnate, membranaceous, light green ; 
pinna petiolate, distant and subopposite, deltoid-acuminate, ¿-1 inch long, 
8-6 lines broad, spreading; pinnules sessile, distant, pinnate below, pinnatifid 
above, cut down quite to midrib of pinne, decurrent, linear-oblong, obtuse,
