238 NOTES ON THE FERN-FLORA OF CHINA. 
from Ceylon. Neither Mettenius nor Baker have apparently ever seen 
this species from Japan. 
Mr. Sampson has detected in shady parks at Canton an Asplenium 
in all respects identical with the Fern distributed from Ceylon under 
n. 1247 by Dr. Thwaites, by whom it is regarded as a bipinnate form - 
of A. Schkuhrii, Mett. ; whilst I cannot myself see how it is to be dis- 
tinguished from the West Indian 4. radicans, Schk. 
I have received from Father Armand David specimens of Scolopen- 
drium Sibiricum, Hook., gathered from cold alpine rocks near Jehol. 
Aspidium deveanm, Kze. (intermedium, J. Sm.) was found, in June 
1865, along the West River, in the province of Canton, by Mr. Samp- 
son. I give the above name and synonym on the authority of the late 
Professor Mettenius, to whom I sent a specimen, whose judgment with 
regard to Kunze's Ferns is unimpeachable, he having full aecess to that 
author's herbarium. Mr. Moore, also, from referring in his * Index’ 
both Kunze's and J. Smith's species to the variety 8 of his Sagenia 
coadunata, evidently considers them identical. The present is pre- 
cisely the same as Dr. Thwaite’s n. 1358, which Sir W. Hooker doubt- 
fully regarded as a var. B. minor of 4. giganteum, Bl., whilst he referred 
J. Smith's intermedium to the typical form of that species, and placed 
A. devezum as a synonym of J. cicutarium, Sw. Dr. Thwaites's n. 
1357, again, which he considers, no doubt rightly, as the 4. giganteum 
of the * Species Filicum,’ Professor Mettenius said is the 4. paradoaum 
of Fée; whilst under the same number Gardner appears to have sent 
to Kew the very similar 4. membranifolium, Mett., or 4. fuscipes, Wall., 
with which latter name, indeed, my first specimen of 4. paradoxum 
received from Dr. Thwaites was ticketed. This confusion in nomen- 
clature renders it difficult to speak with certainty; but I believe Z. 
devezum has only heretofore been found in Java, the Philippines, and 
eylon. An invaluable revision of some of the species of this excep- 
tionably difficult genus, by the lamented Leipzig Professor, will be 
found in the Annales Mus. Lugd.-Bat. i. 225, seq. 
Mr. Sampson gathered beautiful specimens of Aspidium odoratum, 
Bory, on the singular isolated limestone rock called Kai-kun-shek, or 
* Cock’s-comb-hill,’ along the West River, 100 miles west of Canton, 
in June 1864, and others in the caverns at Sai-chii-shan, in February, 
1869. Milde records the species from China, on the authority of the 
Petersburg herbarium, therefore, perhaps, from the north of the empire.
