Hypolepis. | FILICES. 69 
1-2 ft. high or more, strong, erect, brown or yellow-brown, slightly rough 
with minute points, naked or pubescent, usually scaly towards the base. 
Fronds 1-3 ft. long, 4-2 ft. broad, ovate-oblong to broadly deltoid, pale- 
green, membranous or subcoriaceous, 4-pinnatifid ; primary and secondary 
rhachises more or less tomentose with crisped hairs, rarely glabrous. 
Primary pinnae 8-20in. long, 4-10 in. broad, ovate or ovate-lanceolate, 
acuminate ; secondary and tertiary lanceolate or oblong-lanceolate. Ulti- 
mate divisions linear-oblong, obtuse or acute, crenate-toothed ; costa and 
sometimes the under-surface more or less pubescent. Sori numerous, rounded, 
placed in the sinuses between the teeth or lobes.. Indusium composed of 
the reflexed scale-like tip of a lobule of the frond, sometimes covering the 
' sorus when young, often very inconspicuous when old.—Hook. Sp. Fil.

IsLanps: Abundant throughout. Sea-level to 2000 ft. 
Also in Norfolk Island, Australia, the Pacific islands, and Java. A most variable 
fern; in habit and general appearance often so close to Phegopteris punctata that the 
suspicion naturally arises that the two species may be forms of one plant, a view which is 
rendered more probable by the fact that the indusium is sometimes so feebly developed 
that the technical distinction separating Hypolepis and the Phegopteris section of Dry- 
opteris is obliterated. Usually, however, Polypodium punctatum can be distinguished by 
the sori being farther from the margin and by the glandular-viscid rhachis and costae. 
Mr. Colenso’s Cheilanthes pellucida, which is kept as a distinct variety in the “‘ Species 
Filicum ” (t. 904), looks different at first sight on account of its stouter habit, broader 
and more obtuse pinnules, and more copious crisped hairs, but is connected with the 
type by numerous intermediates. I am sorry that I cannot maintain Mr. Carse’s 
H. Peirieana, which I take to be a state not uncommon in many parts of the North 
Island. 
2. H. millefolium Hook. Sp. Pil. 11 (1858) 68, t. 958n.—Rhizome long, 
slender, creeping, naked or nearly so. Stipes 3-9in. long, rigid, erect, 
yellow-brown, glossy, smooth or slightly scabrous, glabrous or sparingly 
pilose with crisped hairs. Fronds 6-18in. long, 3-9in. broad, broadly 
ovate or deltoid to ovate-lanceolate, pale-green when fresh, firm or almost 
rigid, 4-pinnatifid ; rhachis and costae more or less clothed with scattered 
crisped hairs. Primary and secondary pinnae ovate-lanceolate, ascending ; 
tertiary +4 in. long, ovate or oblong, cut down almost to the rhachis into 
several entire or sharply-toothed lobes; under-surface glabrous or slightly 
hairy. Sori numerous, small, roundish, placed under a small lobule in 
the sinuses of the pinnules. Indusium composed of the reflexed and 
almost unaltered tip of the lobule-——Hook. f. Fl. Nov. Zel. 11 (1855) 23;
