274 TAKEDA—ASIATIC POLYPODIUMS. 
Heller in the Sandwich Islands (n. 2533) may possibly be referred 
to this variety. 
It is highly interesting to find this Asiatic species in Madagas- 
car and other parts of Africa. Similar* geographical distri- 
bution is also shown by certain other species of this genus. 
I have examined the following specimens of this variety :— 
S. Arrica. Natal (M‘Ken, n. 23, 174; M‘Ken and 
Buchanan, n. 66, 67; W. T. Gerrard, n. 504); near King 
Williamstown (Sim, n. 1588, 1589) ; British Kaffraria (T. Cooper, 
n. 386; D’Urban; R. Baur, n. 2, 942); Transvaal/Natal (Van 
Reenen ; R. Schlechter, n. 6914) ; Orange Free State (T. Cooper, 
n. 1202) ; East Griqualand: Mt. Zuurberg (W. Tyson, n. 1779) ; 
Cape Colony (R. Schlechter, n. 1); Cape of Good Hope (T. 
Cooper, n. 958). 
AFRICA. Ruwenzori: Mau Forest (Scott-Elliot, n. 9198). 
Mapacascar. Tanala (Kitching, 1880) ; Antananarivo (Pool, 
1876). 
Besides those varieties mentioned above, there have been 
described two others, namely var. glaucosorum, Christ * and 
var. caudatum, Makino.+ The writer has been unable to examine 
any authentic specimen of either of them. As far as can be 
made out from the descriptions, the former may belong to P. 
excavatum, while the latter represents P. nudum. At any rate, 
neither of these appears to the writer to be a variety of P. 
lineare. 
2. P. eilophyllum, Diels. 
This species is closely allied to the preceding ; it differs, how- 
ever, above all, in the sori being situated quite close to the 
midrib and oblong in shape. 
Christ has mistaken this species for P. Lewtsii, Bak., and has 
given a description and figures in the Nuovo Giornale Botanico 
Italiano, n. ser. vol. iv, 1897, under the latter name. He also 
considers the present species to be an extreme form of P. 
lineare,t an opinion not to be approved. 
This plant was first described as P. involutum, Bak.,§ and, as 
the same name had been used already, has been altered by Diels 
to P. eilophyllum.\| I have seen the following specimens :— 
Hupeh : without precise locality (Henry, n. 6859) ; Shensi: 
Mt. Thae-pei-san (Giraldi, Aug. 1876); Yunnan: Mengtsz, 
woods 6000 ft., on tree (Henry, n. 92498).
