I. F1L1CES. 
3G1 
in outline, 3- or 3-pinnate, rarely pinnate ; stipes 6-10 in. high, minutely 
scabrid below, smooth above, polished, black, as is the glabrous rachis ; pin- 
nules few, stipitate, % in. long, rigid, glabrous, often glaucous below or mi- 
nutely roughened, obliquely oblong, obtuse, upper and outer margin crenate 
or lobed, lower margin entire. Sori numerous, small ; involucre upon the 
lobes, reniform or suborbicular, with a narrow sinus. — A. formosum, A. Rich. ; 
A. Cunn., not of Brown. 
Northern and Middle Islands : common, Banks and Solander, etc. Specimens 
growing in dense woods have sometimes variously lobed pinnules. 
6. A. fulvum, Raoul; — FI. N. Z. i. 33. Rhizome stout, creeping, 
scaly. Frond 1-3^ ft. high, olive green, ovate-deltoid, sub-pedately 3- or 4- 
pinnate; stipes scabrous, black; rachis scabrous, strigose above ; pinnules hard, 
coriaceous, glabrous above, with strigose stalks, hirsute or setulose below, 
obliquely dimidiate-oblong or subfalcate, obtuse, lobulate. Sori on the 
lobules, numerous, rather large; involucres orbicular-cordate. — Hook. Sp. 
Fil. ii. 53. t. 85 A. 
Northern aud Middle Islands : rather common in dry woods, Raoul, etc. The co- 
riaceous hispid pinnules and larger sori distinguish this at once from A .formosum ; and the 
ramification and sori on the lobules from A. liispidum, which it approaches very closely. 
13. HYPOLEPIS, Bernhardi. 
Rhizome stout, creeping. — Fronds usually large, 3-4-pinnate, often glan- 
dular-pubescent ; veins forked, free, never netted. Sori globose, near the 
margin, on the tips of the veins, not confluent, covered more or less com- 
pletely by an incurved tooth of the frond, which forms a spurious involucre. 
This genus is, I think, only a section of Roly-podium , the so-called involucre being merely 
the incurved tip of the segment on which the sorus is placed. In proof of this, the E. tenui- 
folia may be seen to pass directly into Polypodium rugulosum. As, however, these genera 
are kept distinct by all authors, I have retained Eypolepis. The following species mav 
prove forms of one or two at the most. 
Frond 2-5 ft., deltoid, 3- or 4-pinnate, glandular. Rhizome scaly . 1. E . tenuifolia. 
Frond 6-12 in., deltoid, 3-pinnate, glabrate. Rhizome naked . . . 2. H. Millefolium. 
Frond 6-18 in., rigid, ovate-elongate, glabrous. Rhizome scaly and 
woolly j 3. E. distans. 
1. H. tenuifolia, Bernhardi ; — FI. N.Z. ii. 33. Rhizome long, stout, 
creeping, scaly. Frond large, sometimes 3 ft. broad, deltoid, glandular- 
pubescent or glabrate, rather membranous or coriaceous, pale or dark green, 
3- or 4-pinnate ; stipes 1-3 ft. high, stout, erect, brown, scabrid or pubes- 
cent ; rachis glandular-pubescent, rarely glabrous ; primary brandies spread- 
ing, ovate or oblong, acuminate, secondary and tertiary more lanceolate ; 
pinnules sessile, linear-oblong, obtuse, pinnatifid, segments oblong, obtuse, 
crenate-toothed, the teeth forming reniform involucres. — Hook. Sp. Fil. ii. 
60. t. 19 ; Cheilanlhes arborescens, Swartz ; C. pellucida, Colenso ; C. ambigua, 
A. Rich. ; C. dicksonioides, Endlicher ; Lonchitis tenuifolia , Forst. 
Northern and Middle Islands, abundant : Banks and Solander, etc. Kermadec 
Islands, Macgillivray. A common Australian and Tasmanian fern, found also in many other 
parts of the world. Forster erroneously described it as arborescent. 
3. H. Millefolium, Hook. Sp. Fil. ii. 68. t. 95 ; — FI. N. Z. ii. 33.
