AsPLENiUM. (See page 43.) 
1. As})knium elongatuni. Caudex a small thick rhizome sparsely scaly, stipites 6-8 inches long, csespitose, and as well as 
the compressed rachis pale-brownish-green and sub-furfuraceous with small lacerated deciduous scales, fronds pale-green 8 to 12 inches long, 
oblong, suddenly acuminate, coriaceo-membranaceous opa(iue pinnate, pinnae 1-2 inches long, petioled horizontally-patent, gradually smaller, 
upwards approximate (in general), oblong quite straight or sub-falcate, very obtuse, strongly serrated, the base truncato-cuneate oblique, 
superior base distinctly auricled, inferior sub-excised, terminal pinnae narrow elongated, acuminate pinnatiiido-serrate, sometimes twice or 
thrice as long as the rest, veins simple oblique, sori copious on almost every vein, short-linear intermediate between the margin and the 
costa, involucres narrow-linear, very firm. Hook. Sjy. Fil. iii, 117. — Sw. Si/n. Fil.,p. IQ.—Kze. Bot, Zeit. vi, ^. 174. — Metten. Asplen.,2}.

2. Asplenium laserpitiifoliuin. (Lam.) Caudex rather stout, sub-repent clothed at the extremity with copious satiny ferruginous 
subulate scales, stipites aggregate 3-4 inches to a foot long, lurid-brown, fronds a span to 2-3 feet long, ovato-lanceolate finely acuminated, 
membranaceous often delicate green, 3-4 pinnate, the surface opaque, primary pinnae 3 inches to a span long, petiolate, from a broad base, 
broad-lanceolate finely acuminate into an incised cauda, secondary pinnai 1-3 inches long, ultimate pinnules and segments small for the 
size of the fronds, 3-5 lines long, cuneate undivided or deeply pinnatifid or 3-lobed, the lobes or segments generally narrow-cuneate, some- 
times broad, incised or toothed at the apex, veins flabelliform, nearly erect parallel, sori linear, rather short, 2-4 on a pinnule or segment, 
often exactly opposite to each other and opening face to face, involucres membranaceous. Hook Sj). Fil. iii, 171. — Lam. EncycL, p. 310.

3. Asplenium spatkulinum. (J. Sm.) Stipites 6 inches and more high, quite smooth and naked lurid-brown, fronds U feet long, 
broad, or ovato-lanceolate, acuminate coriaceous, dark brown when dry and very opaque, quite free from scales, bi-pinnate in the perfect 
state, pinnate at the very apex, sometimes pinnate with pinnae from an unequally cuneate and auricled base entire, and others deeply 
pinnatifid at their base or sub-piunate, pinnae lanceolate broad at their base, pinnules or lobes obovate, the former tapering at the more 
or less oblique cuneate base, so as to be spathulate always, more or less serrated towards the apex, ultimate ones more or less confluent 
into an acuminated serrated apex, intermediate ones frequently decurrent so as to form a winged rachis, veins erecto-patent, flabellate 
conspicuous and with the long linear sori giving a striated appearance to the pinnules, involucres firm-membranaceous narrow. Hook. S]).

Diplazium. (See page 53.) 
1. Diplazium lanceum. (Thunb.) Caudex long-repent, rooting sparingly scaly, stipites distant 4 inches to a span long, slender, 
thickened at the base, and paleaceous with black scales, fronds chartaceous, firm opaque longer than the stipes, rarely an inch wide, lanceo- 
late attenuated and acuminated at each extremity entire, sometimes a little repand, costa slender prominent beneath, veins horizontal, 
fascicled, the superior and sometimes the inferior branch only fertile, Sori linear distant remote from the costa, often diplazioid, Hwk.
