7. P. neo-guineense Copel. spec. nova. 
Species P. membranaceo Don et P. punctate Swtz. affinis, frondibus 
40-50 cm longis, 5-6 cm latis, sessilibus, anguste oblanceolatis, utrinque 
sensim angustatis, eaudatis, integris, membranaeeis, translueentibus; venis 
lateralibus usque ad marginem protensis, obliquis, venis secundariis costae 
parallelis; areolis baud parvis; soris miiiutis, superficialibus, irregulariter 
adspersis. 
No. 335, Lakekaniu. 
This species differs from P. memhranaceum in the irregularly scattered sori, 
from P. punctafitm in the extreme thinness, and from both in the very acute 
angle between costa and main veins. 
8. P. g loss! pes 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. suhgeminatum 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, 2j 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 occasirinally 
iliet in P. Phymatodes. This might be specifically distinguished by the group of 
characters, but T have preferred to leave it where it clearly has a very close 
affinitv. 
10. Polypodium Kingii Copel. spec. nova. 
Rhizomate scandente, 2-3 mm crasso, paleis nigris peltatis marginibus 
angustis laete brunneis adpressis obtecto; stipite articulato, ca. 6 cm alto^ 
ad pedem paleis minutis panels vestito, alitor glabro; fronde glaberrima, 
ca. 15 cm alta et lata, basi vix brevissime cuneata, in specimine meo 
profunda quinquelobata, sinubus rotundatis, segmentis integris valde 
acuminatis, terminale late, lateralibus angustius lanceolatis, papyraceo- 
coriaceis ; venis nigris, conspicuis, seriem unam vel in segmento terminale 
dnas areolarum praestantium efformantibus, baud ad marginem protensis, 
venulis oceultis, plerumque hamatis; soris ultra 1.5 mm latis, globosis, 
superficialibus. 
No. 122; No. 366, from Saniarai, 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 tiiis 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 tlian 
the fertile.
