Nephrodium {Continued) 
2. Nephrodium extensum (Blume) Stipes 1-1^ foot long slightly scaly at the base— fronds 1^ to 3 feet or more long l-\h 
broad oblongo-lanceolate, acuminate sub-membranaceous, copiously pinnate, pinnatifid at the apex, pinnje numerous approximate, sub-hori- 
zontal 8-12 inches long, in the broadest part of an inch broad, from a broad sessile base linear oblong, finely acuminated, glabrous, pin- 
natifid, about half way down to the rachis, the acumen entire, segments narrow, ovate or oblong, or oblong linear sub-falcate, entire, sub-acute, 
lowest pairs of veinlets angularly uniting, the rest free, sori copious but solitary on the veinlets between the costule and the margin 
strictly confined to the segments, or extending to the lowest veinlets, so that the disk is soriferous, involucres, small reniform glabrous.

3. Nephrodium ahruptum (Presl.) Caudex stout, stipes very stout, 2 feet and more long, fronds ample 2-3 feet long, 1 to li 
feet broad, firm coriaceo-chartaceous, glabrous, pinnated, pinn« large 6 inches to 1 foot long, f to 1^ inches broad, sub-sessile from a 
truncated or short cuneated broad base, oblong, finely acuminated, shortly lobato-pinnatifid at the margin, lobes rounded, obtuse and 
sub-erose-truncate, or acute sub-falcate, (inclined towards the apex of the pinnoe,) lowest pinnae often dwarfed, costules slightly elevated, 
numerous, veinlets 6, 8 or 10 pairs (according to the space between the costa and the sinus of the lobes) united and then forming a 
spurious intermediate costule, 3 or 4 only of the veinlets free within the short lobes, sori copious each on the middle of the veinlets in 2 
distinct lines, or series between each pair of costules never extending to the lobes, involucres rotundato-cordate, sub-ciliate or glabrou.«, 
soon deciduous. — Hoolc. Sp. Fil. iv. 78 (the fertile fronds are sometimes considerably contracted, and sometimes as broad as the .sterile 
Qjieg). — Aspidium multilineatum. Wall. Cat. n. 353 Aspidium prionophyllum. Wall. Cat. n. 355. A variety only. — A. pennigerum. BL

4. Nephrodium Arbuscula (Desv.) Caudex creeping, stipites approximate, a span to a foot or more long, fronds firm-membra- 
naceous, scarcely sub-coriaceous, pubescent 1-2 feet long, a span broad, oblong-lanceolate, acuminate a good deal yet abruptly attenuated 
at the base, pinnated, pinnie approximate sub-petiolate from a dilated base, frequently auricled above, and rotundate below, narrow-oblong 
gradually and finely acuminated, coarsely crenato-serrate, lower ones (several pairs) dwarfed, remote sub-deltoid and sub-trilobed, three or 
four pairs of the veinlets anastomosing, a few free veinlets only in the teeth, sori solitary near the middle of each veinlet except on the 
teeth, indusium small reniform.— //oo^, Sp. Fil. iv. 74.— Aspidium Hookeri. Wall. Cat. n. 338.— Asp. puberulum. Wall. Cat. n. 338.—

5. Nephrodium unitum (Sieb.) Root long creeping underground, densely rooting, stipites a span to a foot and more long, stout 
glossy brown ; fronds 1-2 feet long, rigid-coriaceous oblong acuminate, suddenly contracted and attenuated at the base (by the dwarfing of 
the pinnee there) glabrous above, cano-tomentose beneath, especially on the rachis costal and veins, pinnated, pinnas numerous approxi- 
mate 4-6 inches long erecto-patent from a truncated sessile sub-hastate base, linear-oblong gradually acuminated 3-6 lines wide, the 
margin pinnatifid, lobes short, traingular, ovate, acute, rigid, the margins a little reflexed, veinlets very prominent beneath 3 or 4 of the lowest 
pair uniting, and at their junction excurrent and forming as it were a false or intermediate vein reaching to the sinus, sori copious on all 
the veins crowded, at length confluent, involucres small reniform at length glabrous— ZTooi. Sp. Fil. iv. p. 81 -—Sieher Syn. Fil. n. 43
