3. Lastrea deltoidea. (Bedel.) Caudex erect, fronds about 1 foot long, glabrous, deltoid-ovate, bi-pinnate with the pinnules deeply 
pinnatifid, pinnai lanceolate acuminated, the 2 or 3 lower pair 4 to 5 inches long, getting gradually smaller towards the apex, pinnules 
narrow lanceolate | to inch long, deeply pinnatifid, segments obtuse, crenated, and spinuloso-dentate, the primary vein of the pinniiles 
flexuose, veinlets pinnate, terminating with a thickened apex just within the margin, one to four of the veinlets soriferous at their apex 
involucres reniform glabrous. Lastrea sparsa var. lata. (Moore.) Certe species distincta. Thwaites En. 
Nearly allied to Lastrea sparsa, (Plate CIII of this work,) but its very broad deltoid form seems sufficiently to distinguish it. 
Ceylon. (C. P. 1368, 1369, 3383.) 
PLATE No. CCXLVIII. 
4. Lastrea Blumei. (Hook.) Stipes very shaggy with long linear rufous scales, main and partial rachises rufo-pubescent and 
copiously furnished with rufous scales, fronds very large, tri-pinnate with the pinnules, piimatifid to nearly the base, pinnules obtuse, 
entire or inciso-serrate, sparingly hairy above and pubescent on the costa on both sides, veins pinnate, extending to the margin, soriferous 
about their centre, involucres fimbriated. Aspidium intermedium, Bl. En. Fil. Jav., p. 161, ( not nj others.)—^. (Lastrea) Blumei, Hool-.

PLATE No. CCXLIX. 
PLATE No. CCL. Is a figure of Lastrea flaccida, Hooker, from Ceylon, (C. P. 3802.) Plate No. XCIX of this work is tlie 
Lastrea tenericaulis (Hooker), and the name should be accordingly altered ; if really distinct, the two species are very nearly allied, teneri- 
caulis only differing from flaccida in being more compound, and I have specimens which seem to connect the two. 
Note. — PoJi/stichum hi-aristatum. (Blume.) C. P. 3275 is I believe only one of the numerous varieties of P. aculeatum, (Sw.) 
Pohjstichum anomnlam, (Hook. et. Grev.) C. P. 3504 is very curious in having its fructification on the upper side of the frond, it does 
not seem otherwise to differ from some forms of P. aeideatum, and is probably an abnormal form of that species. 
Nephrolepis. (Sec page 32.) 
1. Nephrolepis ohliterata. (Hook.) Caudex very long filiform, here and there sub-squamoso-tomentose rooting with few short- 
fibres, stipites scattered short 1-2 inches long and as well as the rachis dark-brown sub-pubescent, fronds 3-14 inches long, oblong or 
linear-oblong, membranaceous, invariably black when dry, pinnated, pinnae from inches long, horizontally patent, rather distant 
dimidiato-oblong, obtuse or acute, rarely acuminate, obliquely cuneate at the base, sessile, straight or sub-falcate, superior base truncate and 
parallel with the rachis, frequently with a sharp auricle, the margin entire or crenate or lobato-dentate especially on the fertile pinnte, costa 
slender flexuose, veinlets forked, upper branch bearing sori at the apex, a little distance from the margin, involucre small cordato reniform, 
soon obliterated. Hoolv. Sp. Fil. iv, p. 154. — Nephrodium obliteratum. Brown. Prodr. Fl. Nov. IIolL, p. 148. — A.spid. undulatum,

AcROPHORUS. (See page 3.) 
1. Acrophorus affinis. (Moore). Caudex creeping, thick, clothed with long narrow subulate scales, fronds ample, tall, ovato- 
lanceolate, membranaceous, 3-4 pinnate or supra decompound, primary pinnae petiolate, ovato-lanceolate acuminate, secondary petiolate 
oblong-ovate, pinnules ovate, deeply pinnatifid, the segments ovate acute, sub-falcate, entire or generally (the fertile ones) with a tooth on 
the inner margin, involucres small hemispherical or sub-reniforni placed near the centre of a segment below the sinus of the tooth, veins 
slender, black. Hook. Sp. Fil. i, jMge 158.— Leucostegia affinis, J. Sm. En. Fil. Philipp. I. c. (name only j. 
Ceylon. (C. P. 1384.) Very like A. pulcher (Dav. ckserophylla, Wall.) but with a very different caudex.
