XII, C, 1 Copeland: New Species Borneo Ferns 61 
fern in Luzon and have called it P. hirtellum in error. I now believe it to 
be P. Reinwardtii. Grammitis nana Fée is also described as having simple 
veins; whatever it is, the name cannot be transferred to Polypodium. As to 
the venation of P. lasiosoruwm, van Alderwerelt, Malayan Ferns 580, says 
“veins not discernible,”—-which may depend on how it is examined. 
My specimens of Polypodium Brooksti are somewhat old and the sporangia 
seem to be naked; those of P. Reinwardtii and P. hirtellum bear a few setae. 
POLYPODIUM CALCIPUNCTATUM sp. nov. : 
Grammitis P. Frederici et Pauli Christ affinis, subglabra et 
punctulis caleareis ornata; rhizomate erecto, paleis lanceolatis 
fulvis dense ciliatis vestito; stipitibus confertis, 3 ad 4 cm longis, 
gracilibus, pilis 2 ad 2.5 mm longis pallidis et rubis vestitis; 
fronde pendente, usque ad 25 cm longa, ca. 13 mm lata, lingui- 
forme, subacuta, deorsum angustata, integra vel rarius obscure 
et late crenulata, crassa, superne glabrescente et ad apices venu- 
larum albo-punctata, inferne sparse pilosa; venis utrinque pin- 
natis, immersis; soris irregulariter a costa fere ad marginem 
adspersis, superficialibus, orbicularibus, inter sporangia pilis 
paucis.

While near to Polypodium Frederici et Pauli of Celebes, this fern has 
a narrower frond, with parallel sides and the form of a narrow P. setigerum, 
less conspicuous and almost naked costa, and thicker texture. 
POLYPODIUM MULTISORUM sp. nov. 
Grammitis, praecedente (P. calcipunctato) affinis; rhizomate 
breve, suberecto, radicibus et sursum basibus stipitum omnino 
obtecto, paleis veris ob dissectionem ipsarum in pilos minutos 
pallidos carentibus; stipitibus multis confertis, 2 ad 4 cm longis, 
filiformibus, pilis pallidis usque ad 2 mm longis densissime 
hirsutis; fronde ca. 15 cm longa, 8 ad 12 mm lata, utrinque 
angustata, subacuta, integra vel saepius late crenata, subcoriacea, 
superne glabrescente, inferne ubique pilosa; venis sinuatis, irre- 
gulariter utrinque pinnatis; soris irregulariter adspersis vel sub- 
3- vel 4- seriatis, oblongis, densissime pilosis, superficialibus. 
Mount Kinabalu, Paka Cave, Topping 1665 (type) 1668, 1682, 1711. No. 
1682 is immature and might be confused with other species, 
While more like Polypodium Frederici et Paul: in form and texture, this 
fern is clearly distinguished by the elongate sori, which remain clearly 
marked by dense tufts of hairs, after the sporangia are removed. 
POLYPODIUM MURUDENSE sp. nov. 
Eupolypodium pinnatifidum anguste lineare; “rhizomate” 
erecto, breve, paleis ovato-lanceolatis brunneis inter stipites ves- 
tito; stipitibus confertissimis, ca. 2 mm altis, vel 1 cm altis et 
sursum alatis, pilis paucis albidis ornatis, mox glabrescentibus ; 
fronde 6 ad 9 cm alta, 2.5 mm lata, in dentes triangulares obtusos
