1. H. tenuifolia, Bernh. an Schrad. Neu. Jowrn. Bot. ii. 34.— 
Rhizome long, stout, creeping, densely clothed with red-brown 
linear scales. Stipes 1-2 it. high or more, strong, erect, brown or 
yellow-brown, slightly rough with minute points, naked or pubes- 
cent, usually scaly towards the base. Fronds 1-3 ft. long, 4-2 ft. 
broad, ovate-oblong to broadly deltoid, pale-greeu, membranous or 
subcoriaceous, 4-pinnatifid; primary and secondary rhachises more 
or less tomentose with crisped hairs, rarely glabrous. Primary 
pinne 8—20in. long, 4-10in. broad, ovate or ovate-lanceolate, acu- 
minate; secondary and tertiary lanceolate or oblong-lanceolate. 
Ultimate 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. 1. 60, t. 89c

KerRMADEC Is~tANDs, NortTH AND SoutH ISLANDS, STEWART ISLAND, 
CHATHAM IsLANDS: 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 Polypodium 
punctatum 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 sepa- 
rating Hypolepis and Polypodium is obliterated. Usually, however, Polypodium 
punctatum can be distinguished by the sori being further from the margin and 
by the glandular-viscid rhachis and coste. Mr. Colenso’s Cheilanthes pel- 
lucida, which is kept as a distinct variety in the ‘‘ Species Filicum’”’ (t. 90a), 
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. 
2. H. millefolium, Hook. Sp. Fil. ii. 68, t. 9583.—Rhizome 
long, slender, creeping, naked or nearly so. Stipes 3—-9in. long, 
rigid, erect, yellow-brown, glossy, smooth or slightly scabrous, gla- 
brous or sparingly pilose with crisped hairs. Fronds 6-18 in. long,
