which has since been separated as a distinct species). 
3. P. carvifolium (Kze.) C. Chr. Ind. Fil. 580 (1906). 
P. aristatum Presl var. carvifolium Maid. & Betche. 
P. coniifolmm Presl. Domin in Bibliotheca Botanica 
XX, p. 57 (1915). 
Rhizome tufted, clothed with lanceolate scales. Stipes 
tufted, 20-60 cm. long*, more or less densely clothed at the 
base with dark, linear-lanceolate scales. Fronds as in 
P. aristatum , except that the scales on the rhackises and 
stipes are dark, flattened and linear-lanceolate, not 
fibrillose. 
Distribution 1 —Eastern Australia, Malaya, Polynesia, 
Japan, China, North India, Natal. 
Queensland: — Recorded from Mt. Lindesay and Lam- 
ington National Park on the southern border, to Rocking- 
ham Bay. 
N.S. Wales: — No data is available as to distribution 
in this State, but the localities listed under P. aristatum 
probably also apply here. 
The last two species are very closely allied, but hav- 
ing seen both plants growing in their natural habitat, I 
have no doubt that they are specifically distinct. In the 
former the base of the stipes is furnished with pale, fine, 
narrow scales which are twisted towards the apex, appear- 
ing fibrillose, and the fronds are scattered along a creep- 
ing rhizome. The latter species, on the other hand, has 
dark-brown, narrow, flattened and rather stiff: scales on 
the stipes, and the fronds are tufted on an erect rhizome.

Rhizome stout, long-creeping, densely covered with 
large, soft, brown, lanceolate-subulate scales. Stipes 
robust, 7-35 cm. long, more or less clothed with brown, 
spreading, deciduous scales. Fronds scattered along the 
rhizome, without the stipes 14-35 cm. long, 8-18 cm. broad, 
lanceolate to deltoid-lanceolate, apex acuminate, rigidly 
coriaceous, both surfaces glabrous except the deciduously 
scaly rhachises, bipinnate or tripinnatifid at the base. 
Primary pinnae erecto-patent, stipitate, deltoid-lanceo- 
late, more or less decurrent on the rhachis, bipinnatifid at 
the base, the lowest pair the largest; ultimate segments
