NEW SARAWAK FERNS.

name was used without description for Cuming 389, from Malacca. PresI, 
Epimeliae p. 86, described Diplazium malaccense from the same number, 
stating explicitly that it included his plant and also D. Schkuhrii — Asple- 
nium ambiguum Schkuhr, pi. 75. Then came Mettenius, Asplenium No. 
208, giving the first diagnosis in connection with the name, Asplenium 
Schkuhrii, ignoring PresTs statement that the Cuming number 389 was 
mixed, citing D. malaccense as a synonym, and making a diagnosis which 
fits the latter. Diplazium Schkuhrii J. Sm. is therefore a nomen nudum, 
and Asplenium Schkuhrii Mett. a synonym of Diplazium malaccense, which 
I construe as a form of Athyrium pinnatum (Blanco) Copel. I have in 
hand also a specimen from Mount Penrissen, Sarawak, alt. 1050 m., Brooks 
lUl, sent as D. acuminatum Bl. The determination is probably correct 
although the fern’s appearance just suggests D. petiolare Presl, which I 
have also reduced to Athyrium pinnatum. Mr. Brooks has also sent a 
fern collected at Bidi in 1908 which is Diplazium petiolare, differing from 
the type only in having a more naked rachis. 
Athyrium elatum (Fee) Copel. 
Diplazium elatum Fee Genera (1850-52) 44. 
Many as are the forms which I construe as Athyrium pinnatum {A. 
silvaticum Milde 1870), this seems decidedly distinct. I have a fragment 
from Kuhn’s herbarium which agrees with Mettnius’ description (Asple- 
nium No. 203) so perfectly that it seems probable that it is a part of the 
specimen he had in hand; and he and Fee cite the same single collection. 
Athyrium Cumingii (Presl) Milde. (?) 
Mount Poe, alt. 900 m. Brooks H5. 
From Luzon to Celebes; new to Borneo. The specimen is not typical 
and may be a distinct species; but this is its nearest affinity. 
Athyrium subserratum (Bl.) Milde. 
Sarawak, Mount Poe, alt. 900 m. Brooks m. 
Previously known from Java and Penang. 
Dennstaedtia cuneata (J. Sm.) Moore, var. obtusa Copel. var. nov. 
Pinnulis obtusis, baud alter forma typicale diversa. 
Sarawak, Paku Bater, collection of the Sarawak Museum. 
New to Borneo; the type from Luzon. Hooker describes the pinnules 
of typical D. cuneata as very obtuse, but is very evidently referring to 
the secondary pinnules, as the primary ones are acute, or often acuminate. 
Histiopteris integrifolia Copel. sp. nov. 
Segmentis stipularibus carentibus vel minutis orbicularibus ; 
pinnulis linearibus, longis, acuminatis, subcordatis, sessilibus vel 
infimis subpedicellatis ; areolis parvis ; soris ad apicem non 
approximatis. 
Sarawak, Matang Road Native collector 768, Bureau of Science. 
This may vrell be the Litobrochia incisa var. integrifolia Bedd. Supple- 
ment (1892) 25, from Perak, which, however, is described as without 
“stipules,” and as having the sorus almost reach the apex. H. stiplacea 
(Hooker) Copel. has large “stipules” and broad pinnules.
