7. P. neo-guineense Copel. spec. nova. 
Species P. membranaceo Don et P. punctato Swtz. affinis, frondibus 
40-50 cm longis, 5-6 cm latis, sessilibus, anguste oblanceolatis, utrinque 
sensim angustatis, caudatis, integris, membranaceis, translncentibns ; venis 
lateralibus usque ad marginem protensis, obliquis, venis s.ecundariis costae 
parallelis ; areolis haud parvis ; soris minutis, super ficialibus, irregulariter 
adspersis. 
No. 335, Lakekamu. 
This species differs from P. membranaceum in the irregularly scattered sori, 
from P. punctatum in the extreme thinness, and from both in the very acute 
angle between costa and main veins. 
8. P. glossipes Baker. 
Nos. 173, 311, Ambasi. 
New Guinea; Cambodia, fide Christensen’s Index. 
The rhizome of No. 311 is densely scaly, but that of No. 173 more sparsely so. 
The fronds are acuminate. 
9. P. Phymatodes L. 
Nos. 176, 241, Ambasi. 
Polynesia to Africa. 
No. 176 has the usual pinnate form, but the sori are up to 5 mm wide. 
No. 241 is determined by Bailey as P. subgeminatum Christ, correctly as far 
as the inadequate diagnosis definitely shows. The rhizome is stout and ivory- 
white; the dwarf-branches bear 1 to 3 fronds, most often, 2; the stipes are 1 
to 3 cm long, and slender. The fronds are lanceolate, about 10 cm long, simple 
and entire; the upper surface densely covered with lime-dots; the sori in a 
single row. Each of these peculiarities, even the geminate fronds, is occasionally 
met in P. Phymatodes. This might be specifically distinguished by the group of 
characters, but I have preferred to leave it where it clearly has a very close 
affinity. 
10. Polypodium Kingii Copel. spec. nova. 
Rhizomate scanclente, 2-3 mm crasso, paleis nigris peltatis marginibus 
angustis laete brunneis adpressis obtecto; stipite articulato, ca. 6 cm alto, 
ad pedem paleis minutis paucis vestito, aliter glabro; fronde glaberrima, 
ca. 15 cm alta et lata, basi vix brevissime cuneata, in specimine meo 
profunde quinquelobata, sinubus rotundatis, segmentis integris valde 
acuminatis, terminale late, lateralibus angustius lanceolatis, papyraceo- 
eoriaceis ; venis nigris, conspicuis, seriem unam vel in segmento terminale 
duas areolarum praestantium efformantibus, haud ad marginem protensis, 
venulis occultis, plerumque hamatis; soris ultra 1.5 mm latis, globosis, 
superficialibus. 
No. 122 ; No. 366, from Samarai, may be the same, but is sterile and old. 
Superficially, this species is very similar to P. pteropus Bl., in spite of the 
fact that the base is hardly decurrent. However, in spite this .time of the 
superficial sori, I believe that it is a nearer relative of P. nigrescens. The sterile 
frond, the collector writes, is simple, and borne lower down on the tree than 
the fertile.
