TAKEDA—ASIATIC POLYPODIUMS. 277 
distincte stipitatae, stipite 2 ad 4 cm. lg., crasso, levi, nigricanti, 
lamina 10-23 cm. lg., I-2 cm. It., lanceolata, apice anguste 
acuminata, subcoriacea, costa prominenti, nigrescenti, nervis 
inconspicuis, pagina superiore nigro- punctata, pagina inferiore 
paleis minutis cuspidato- ovatis nigris parce vestita. Sori inter 
costam et marginem medii, globosi 3-4 mm. diam., superficiales, 
in parte superiore frondis vel saepe ultra medium occurrunt. 
This is perhaps a rare species, or has been confounded with 
some other species of the P. /ineare group. It was first described 
by Mr. Baker in the Gardeners’ Chronicle, n. ser. xiv, p. 494 
(x880), from two imperfect, unusually small fronds. In 1905 
Christ reduced this species to P. lineave as a variety,* but, as I 
have not seen the specimens referred to, I am not es certain 
if his name can be regarded as a synonym of our plant 
This species is characterised by the thick, almost black 
stipe, lanceolate frond, and large globose sori arranged in a 
row between the midrib and the margin, or slightly nearer the 
midrib. 
I have seen the following specimens :— 
Kwantung: Lo Fou Shan, alt. 3100 ft. (ex hb. Hongk., n. 13) ; 
Kiangsi: Kiukiang (Maries); Yunnan: Mengtsz, mt. woods 
to S.E., 6000 ft. (Henry, n. 10,192). 
The last-referred specimen has been determined by Christ 
as P. simplex.t 
8. P. nudum, Kunze. 
For nearly a century P. nudum has been confused with 
P. lineare, and sometimes with P. excavatum. Hooker’s first 
description, accompanied by a beautiful plate, of this plant 
under the name of Pleopeltis nuda was published in the Exotic 
Flora, tab. 63, 1823. Kaulfuss may have been the first to 
reduce this name§ to his Pl. elongata, which was published in 
1824. Later, Hooker himself confused his plant with others. In 
Garden Ferns || and in Species Filicum he uses the name P. /ori- 
_ forme, Wall. (=P. lineare var. loriforme, Takeda) for the present 
plant, and gives for synonyms, amongst others, P/. nuda, Hook., 
Pl. elongata, Kaulf., P. lineare, Thunb., P. Gueintzii, Mett., P. 
excavatum, Willd., and P. phlebodes, Kze./ Thus he evidently 
held a very wide view, which has given rise to much confusion 
in later years.

mined by Christ as P. oligolepidum (Nuov. — Bot. Ital. n. ser. iv, p. 99 [1897])
