ADDITIONS TO THE BORNEAN FERN FLORA. 
285 
Asplenium filiceps Copel. spec. nova. 
Candice lignoso, 5 mm crasso, paleis lanceolatis apiculatis castaneis 
marginibus pallidioribus dense vestito; stipitibus confertis, ca. 10 cm 
longis, tenuibus, viridibus, nt lamina inferiore frondis sparse minnte 
squamulosis, squamulis pallide brnnneis ; fronde simplice 20-24 cm longa, 
20-24 mm lata, utrinque angustata, angustissime longe candata, obscure 
•serrata, subcoriacea; venis liberis; soris vix ad costam et haud ad mar- 
ginem attingentibus, ca. 8 mm longis ; indnsiis albidis persistentibus. 
Tringos (source of Sarawak river), leg. G. J. Brooks, No. 21. 
This species is in the group of A. squamulatum Bl. which seems remarkably 
well represented in this region. It is nearest to A, Natunae Baker, from which 
it differs in margin and texture. It is the most caudate plant in the group. 
Plagiogyria pycnophylla (Kze.) Mett. var. integra Copel. var. nova. 
Marginibus integris, vix etiam ad apices pinnarum serrulatis, pinnis 
gracilibus. 
Mount Bengkarum, near summit, leg. C. J. Brooks. 
Polypodium Zippelii Bl. 
Mount Bengkarum, leg. 0. J. Brooks, No. 33. 
Apparently new to Borneo. 
Dryostachyum ? 
Mr. Brooks collected at the summit of Bengkarum a large fern which is what 
might be expected as a hybrid of Polypodium heracleum and Dryostachyum 
splendens, neither of which is known to occur in Borneo. Only a few segments 
are fertile; these are not at the apex and are not much contracted. The sori 
are composite, but not to the same degree as in Dryostachyum. 
Lecanopteris pumila Bl. 
Matang Mountain, July, 1908, leg. J. Dewitt. 
This is the same fern as is found in Mindanao, and, though notably large, 
can hardly be other than that figured by Blume. 
Vittaria longicoma Christ Ann. Jard. Buit. II 5 (1905) 129. 
Sarawak River, near Tringos, altitude 400 m. leg. G. J. Brooks, No. 17. 
The fronds reach at most a length of '55 cm, the palese are only 4 mm long, 
and the sori are interrupted, but I think it must be this species, known only 
from Borneo. The spores are reniform and the paraphyses have narrowly 
cyathiform heads. This is very near V. isoetifolia Bory, but longer, and the 
paleae are narrower, lesg toothed, and with a very long filiform apex. 
Elaphoglossum petiolatum (Sw.) Urban. 
Summit of Bengkarum, leg. G. J. Brooks, No. 30. 
New to Borneo.
