has about 80 cm of frond with the apex missing and the lower pinnae 
fallen off. 
POLYPODIUM GLOSSOPHYLLUM sp. nov. 
Phymatodes foliis integris; rhizomate repente ca. 5 mm crasso, 
paleis nigris nitidis anguste lanceolatis adpressis 4 mm longis 
dense vestito; stipitibus ca. 1 cm altis, validibus, castaneis, nudis; 
fronde 60-90 cm alta, ca. 7 cm lata supra mediam latissima, 
utrinque angustata, apice acuta, ad basin ipsam plerumque ab- 
rupte contracta, integra, coriacea, glabra, inferne glauca; costa 
inferne tereta, superne plana; venis angulo lato distantibus; 
rectis, fere ad marginem attingentibus, 1 cm inter se distantibus; 
arealis primariis 4 vel 5-seriatis, haud conspicuis; soris inter 
venas biseriatis vel subirregulariter adspersis, plusquam 1 mm

Mount Gewagewa, alt. 300 m, King 388. 
A member of the group leading to P. musifolium BL., related to P. linguae- 
forme Mett., P. mindanense Christ and P. neo-guineense Copel., charac- 
terized by the glaucous nether surface and hardly acuminate tip. 
POLYPODIUM SUBGEMINATUM Christ. 
I have regarded this species as not sufficiently distinct from P. Phyma- 
todes (Philip. Journ. Sci. 6 (1911) Bot. 89), but Mr. King satisfies me that 
they are different. The man in the field sees both resemblances and dif- 
ferences which never show in the herbarium. P. subgeminatum is said to be 
always uniform in size, while P. Phymatodes varies much on the same 
plant, both in size and in form. It does this everywhere, but the variation 
shown by King’s specimens is remarkable, even for this species. 
POLYPODIUM TENUINERVE sp. nov. 
Phymatodes membranacea soris uniseriatis; rhizomate late 
repente, 2.56 mm crasso, paleis appressis castaneis lanceolatis 
4—5 mm longis vestito; phyllopodio brevissimo; stipitibus badiis, 
usque ad 20 em altis, gracilibus; fronde 35 cm alta, 20 cm lata, 
brevi-decurrente, ad alam angustam (ca. 2 mm latam) pinna- 
tifida, glabra, membranacea, viride; segmentis utroque latere 
ca. 7, maximis fere 20 cm longis 1-2 cm latis, valde acuminatis, 
rhachin versus paullo angustatis, integris vel subundulatis; venis 
tenuibus irregularibus, areolas conspicuas non efformantibus; 
soris utroque latere costae uniseriatis rarissime cum soris extra- 
serialibus, leviter immersis, maximis 1 mm latis sed depressione 
minore. 
Cape Nelson, King 364. 
In the immediate group of P. Phymatodes, from all forms of which 
species it differs in texture and in the fine sori. P. flaccidum Christ is a 
coarser fern, much more decurrent, with the segments remote and con- 
nected by a very broad wing.
