I. FILICES. 
[Nephrodium. 
long, linear-oblong, acuminate, deeply pinnatifid ; pinnules in. long, linear- 
oblong, obtuse or acute, quite entire ; veinlets simple, the lower forked. Sori 
numerous, towards the margin ; involucres cordate-reniform, glandular. — 
Hook. Sp. Fil. iv. 88; Aspidium invisum, Forst. ? 
Northern Island, Forster ; Bay of Islands and east coast, Colenso. The var. yS is a 
native also of South Africa ; the typical plant, which wauts the bullate scales, is common in 
the north temperate zone. 
3. Fsl. velutiimm. Hook. f. — Lastrea velutina, FI. N. Z. ii. 39. t. 80. 
Rhizome unknown. Frond rather membranous, deltoid or 5-angled, 1-2 ft. 
high and broad, acuminate, downy with silky hairs on both sides, often glan- 
dular beneath, 2- or 3-pinnate or 4-pinnate at the base, red-brown when 
dry ; stipes long, slender, pubescent, clothed with subulate scales at the base ; 
primary pi nine, 4 in.-l ft. long, broadly oblong, acuminate, long-stalked, 
lowest inferior secondary pinna deflexed, most compound ; pinnules sessile, 
oblong, acute, pinnatifid, segments ovate, obtuse, serrate or crenate ; veinlets 
simple or forked. Sori small, one on each segment ; involucres hairy, red- 
brown, often fringed with glands, sometimes minute or absent. — Aspidium 
velutinum., A. Rich. 
Abundant throughout the Northern aud Middle Islands, Banks and Solander, etc. 
4. N. decompositum, Br. ; — FI. N. Z. ii. 39. t. 79. Rhizome short, 
stout, creeping, black. Fronds as in N. velutinum , but very variable, often 
smaller, always green when dry, glabrous or pubescent, segments more acutely 
serrated, sometimes only pinnate, pinnules often elongate or caudate ; stipes 
with fewer scales at the base. — Hook. Sp. Fil. iv. 146 ; N. ylabellum, A. 
Cunn. 
Abundant throughout the Northern and Middle Islands, Banks and Solander , etc. 
Kermadec Islands, Macgillivray. Also found in Tasmania, Australia, Norfolk Island, 
and the Pacific islands. 
5. 3NT. hispidum, Hook. Sp. Fil. iv. 150. — Polystichum hispidum, J. Sm. ; 
— FI. N. Z. ii. 38. Rhizome long, stout, creeping, covered with subulate 
brown scales. Fronds 1-2 ft. high, rigid, ovate-acuminate, 3- or 4-pinnate, 
pubescent beneath ; stipes stout, and rachis and costa hispid with long rigid 
spreading or deflexed bristles with a swollen base ; primary pinnae 3-6 in. 
long, stipitate, ovate, acuminate, lowest pair deltoid ; pinnules decurrent, nar- 
row lanceolate, in. long, deeply serrate, segments pungent ; veinlets soli- 
tary in each segment. Sori solitary on the segments ; involucre flat, orbicular 
or reniform, dark brown. — Aspidium hispidum, Schkuhr, Fil. t. 49; Polypo- 
dium setosum, Forst. 
Throughout the Northern and Middle Islands : abundant, Banks and Solander , etc. 
I have followed the ‘ Species Filicum ’ in referring this to Nephrodium, but the involucre is 
more that of Polystichum. 
Aspidium Serra, Forst. Nothing is known of this plant, which is probably the common 
tropical Nephrodium propinqaum, Br., or N. unitum , Sieb., which Forster gathered in the 
South Sea Islands. Raoul enters it into his catalogue as having been collected at Akaroa 
by himself, probably confounding it with something else. 
Mrs. Jones (Handbook of N. Z. Ferns) mentions another species of Nephrodium as 
having been found near to hot springs, which differs from N. molle in the pinnte tending up- 
wards, and the position of the sori.
