- discovered or described since 1874 . 
307*. P. induratum, Baker, sp. n. Rhizome slender, wide-creeping. 
Stipe wiry, naked, 3-4 in. long. Frond simple, linear, rigidly 
coriaceous, glabrous, 8-9 in. long, J in. broad at the middle, 
narrowed gradually to the base and apex. Veins immersed, 
quite hidden. Sori middle-sized, globose, superficial, forming 
a single lax row of each side of the midrib, with a few others 
forming an outer row at the middle of the frond. New Guinea-: 
Mount Yule. Received from Sir F. Mueller, April 1891. 
311. P. superficiale, Blume. Has lately been found in West China 
by Faber. 
311*. P. sarawakense, Baker, in Journ. Linn. Soc. XXII, 228. 
Sarawak, Borneo, Bishop Hose . Very near P. superficiale. 
311*. P. papuanum, Baker, in Malesia, III, 48. Mountains of New 
Guinea, Beccari. 
311*. P. buergerianum, Miquel, Prolus. 334. Japan: regathered 
lately by Dickins. P. hrachylepis , Baker, in Gard. Chron. n. s. 
XIV, 494, from Central China, province of Kiu-Kiang, 
Maries, is probably the same species. 
311*. P. Steerei, Harringt. in Journ. Linn. Soc, XVI, 32. Formosa, 
Steere. 
312. P. schomburgkianmn, Kunze. An earlier name is P. mega - 
lophyllum , Desv. Ann. Linn. Soc. Par. VI, 226. 
315. P. linearifolium, Hook. Has now been found in Japan by 
Maximowicz, Moseley, and Dickins. 
316. P. glabrum, Mett. Authentic specimens from R. Brown’s 
herbarium show this to be P. confluens, R. Br. Prodr. 146, a 
much earlier name. It is also Drymoglossum Cunninghami, 
Moore, Ind. Fil. 343. Norfolk Island. 
317. P. angustatum, Sw. New South Wales to be omitted. 
318. P. samarense, Mett. There is some confusion here : Cuming’s, 
323, on which Gymnosorium samarense , Presl, Epim. 140, is 
founded, is Niphobolus varius , to which it was long ago referred 
by John Smith ; but I do not think the plant, of which a scrap 
is figured by Mettenius, Polyp., under this name is identical. 
Our specimen of Cuming’s No. 93 is very near P. angustatum , 
but probably distinct by its crowded sori. 
322*. P. Annabellae, Forbes, in Journ. Bot. 1888, 33, tab. 280. 
Mountains of New Guinea, H. O. Forbes . Differs from 
P. lycopodoides by its cordate-orbicular sterile frond.
