140 DR. H. F. HANCE’S SUPPLEMENT TO 
but accidentally omitted by Mr. Bentham. 1 have a charac- 
teristic specimen gathered by myself still at hand. An ambi- 
guous fern as to position and affinities (Cfr. Hook. fil. Handb. 
N. Zeal. Fl. i. 361, 381; Griseb. Fl. Brit. W. Ind. 667; Mett. 
Monogr. Phegopt. 13), diffused over most of the warmer parts of 
the globe. 
*Aspidium urophyllum, var. uniseriale, mihi. (=Polypodium gra- 
nulosum, Benth. Fl. Hongk. 459, but not of Presl.) 
*Aspidium simplex, mihi. (=Meniscium simplex, Hook.; Benth. Fl. 
Hongk. 457.) 
I cannot keep Phegopteris, to which Mettenius had already 
reduced Meniscium (Fil. Lechler. ii. 20), separate from Aspidium, 
of which it does not even form a natural section, the different 
species being very variously related. Abundant evidence exists 
that many usually nudisorous species are oceasionally indusiate, 
so that I cannot accept this as a generic character t. All differ 
from Polypodium by the continuity of rhizome and stipes. 
*Aspidium filix-mas, Sw.; Milde, Fil. Europ. 118. (2 Aspidium Cham- 
pioni, Benth. Fl. Hongk. 456.) 
Most of the South-Chinese specimens are referable to the 
variety paleaceum ; but others belong to the common European 
form. 
67. Aspidium erythrosorum, Eaton. (=Nephrodium erythrosorum, 
Hook. Sp. Fil. iv. 120, t. 253.) 
Not common on the island, and found also on the mainland 
near Canton, in Fokien, the islands of the Korean Gulf, and 
Japan. 
*Aspidium varium, Sw.; Hook. Sp. Fil. iv. 30, t. 226. (=A. opacum, 
Hook.; Benth. Fl. /Tongk. 456.) 
Distinct as good typical specimens of the above three ferns 
appear (and the last is generically separated from the other two 
by Mr. Baker) they yet run together so imperceptibly that 
examples occur which cannot be referred with certainty to either, 
and I do not doubt that they are all forms of one species. 
may add that the bright red hue of the indusia in A. erythrosorum 
is not a constant character, and is sometimes equally conspicuous 
t “ Phegopteridis species quasi per vim a proximis cognatis, que nunc in 
genere Aspidio sunt, diremte sunt. Mentionem faciam solum PA. cochleate et 
pyenolepidis, que in distributione naturali juxta Aspidium vestitum ponendi 
sint, ita ut in quibusdam generibus indusii absentia vel przsentia non nisi ad 
vicinas species secernendas adhiberi possit" Kunx, Fil, Afr. introd, 4.
