pinnatifida, in vernatione pilis brevissimis albidis vestita, glabres- 
cente, papyracea, sinubus inter dentes dentibus ipsis reversis 
aequalibus; vena in dente quoque una, simplice, soro tantum 
uno, inframediale, subsuperficiale. 
Mount Murud, native collector, 2924 (Bur. Sci.), December, 1914. 
Nearer to Polypodium subpinnatifidum than to P. alternidens; differing 
from -the former in having almost sessile, narrower fronds and triangular, 
not rounded, segments; from the latter in the closer teeth and thinner 
texture. 
POLYPODIUM BRACHYPODIUM sp. nov. 
Species P. colorato Copel. similis et affinis, paleis mollioribus 
integris distincta; rhizomate 3 ad 4 mm crasso, calcareo, paleis 
rufo-castaneis peltatis sensim in caudam angustatis 5 mm longis 
integris mollibus vestito; phyllopodiis brevissimis; stipitibus 
inter se ca, 4 mm distantibus, 10 ad 18 cm altis, glabris, atro- 
fuscis vel (frondium juvenalium) stramineo-fuscis; fronde 
usque ad 30 cm alta et 7 cm lata, acuminata, pectinata, vix deor- 
sum angustata, rhachi atro-fusca, nuda; segmentis utroque latere 
usque ad 60, fere horizontalibus, 3 ad 4 mm latis, acutis, apices 
versus serrulatis, ala angusta confluentibus, papyraceis vel sub- 
chartaceis, opacis, infimis decurrentibus; venis deorsum seriem 
unam areolarum includentibus, aliter liberis, furcatis, venis in- 
clusis nullis, apices versus segmentorum liberis, furcatis, tum 
demum simplicibus; soris ad ramos inferiores acroscopicos vena- 
rum, costae quam margini propioribus, superficialibus, parvis, 
utroque latere costae usque ad 18.

Very similar in appearance to Polypodium coloratum, but larger than any 
known specimens of the latter, with closer fronds, and distinctly different 
paleae; the costae of the segments are straight in P. brachypodium, but 
wavy above the middle in the type of P. coloratwm. 
Polypodium cesatianum Baker is probably a fern of this most interesting 
Bornean group, as is certainly true of the fern described under that name, 
as a Eu-polypodium, by van Alderwerelt, Malayan Ferns, 603. In my judg- 
ment, this name is without standing in systematic botany. Baker published 
it without a diagnosis, merely stating that Beccari’s plant, P. papillosum 
Cesati, non Blume, was a distinct species. Cesati suggests differences from 
true P. papillosum, by saying that such may be due to the state of develop- 
ment of his very small specimen; but all he tells about it is that it agrees 
with P. papillosum in not having the lower pinnae reduced—which certainly 
is no diagnosis. Beccari and Christ merely list the plant; and the first 
description, based on a collection by Hallier instead of on the original, was 
published by van Alderwerelt, in English and in 1909. 
Judging by place of collection, Beccari’s plant is likely to be P. coloratum 
Copel., 1908, which I published without suspecting that I might have P. cesa-
