PHANEROSORUS Copel. genus novum. 
Genus Matoniacearum, ob rhacliin frondis sympodialem, pinnas dicho- 
tomas et soros hand ad anastomoses vennlarum plurium impositos a 
Matonia separandum. 
Phanerosorus sarmentosus (Bak.) Copel. comb. nova. (Plate III.) ( Mato- 
nia sarmentosa Baker Journ. Linn. Soc. Bot. 24 (1887) 256.) 
Dr. Foxworthy lias collected for me at Niali, Sarawak, the type locality, very 
copious material of this fern. The ultimate divisions of the frond are sometimes 
entire, sometimes sinuate or broadly crenate; they are at most 14 cm long. The 
sori are sometimes borne, as hitherto supposed, on free veinlets ; but more often 
on an anastomosing vein which incloses a costal areola. Such costal areolae 
without sori are not uncommon. Well-developed specimens fruit very copiously. 
13 is a common number of sporangia in a sorus. The indusium is not strongly 
inflexed as in Matonia. The sporangia are flattened, not as round as in Matonia; 
and the annulus, which is irregular, has many more cells. Phanerosorus and 
Matonia are decidedly more distinct than it is customary to expect genera to be 
in other families. 
Dryopteris athyriocarpa Copel. spec. nova. 
Khizomate erecto, parvo, 3 mm crasso, stipitibus 20 cm altis, purpureo- 
nigris, paleis castaneis, lanc-eolatis, valde attenuatis, deorsum dense sursum 
sparsissime castaneo-paleaceis, aliter glabris; fronde ea. 20 cm alta, 7 cm 
lata, acuminata; rachi infra deorsum castanea alibi viride, supra et costa 
villosis infra fere glabra; pinnis plerisque sessilibus, liorizontalibus, 35 mm 
longis, 12 mm latis, obtusis, ad alarn angustam pinnatifidis, costa infra 
baud pilosa, pinnis infimis major ibus detlexis segmentis earum fere ad 
mediam pinnatifidis; segmentis utroque latere ca. 10, lineari-oblongis, 
obtusis, inferioribus inciso-serratis, superioribus integris, minute ciliatis, 
supra ad venulas pilosis infra ubique etiam ad indusia glanduligeris, 
membranaceis, venulis simplicibus; soils polymorphis, nunc dryopteroi- 
deis, multo saepius athyrioideis, rarius rectis, indusio vix coriaceo.

This species differs from its nearest relative, D. viscosa (J. Sm.) C. Clir. in 
the naked underside of the costa, thinner texture, more cut fronds, and chiefly 
athyrioid sori. In the original Lastrae a viscosa, Cuming J/01, from Malacca, there 
are a few athyrioid sori and the stipe is almost glabrous; Philippine plants 
referred to D. viscosa are much more hairy throughout. 
Dryopteris Hewittii Copel. spec. nova. 
Khizomate breve repente, paleis lanceolatis brunneis vestito; stipitibus 
gracilibus, rectis, rhacliidibusque sulcatis et in sulca pilosis, aliter glabris, 
frondium sterilium ca. 10 cm, fertilium ca. 20 cm altis; fronde sterile 
ca. 12 cm alta, 5 cm lata, acuta; pinnis proximis, rectis, obtusis, apices 
versus grosse inciso-serratis, rhacliin versus fere integris, truncato-uniauric- 
ulatis, 25 mm longis 7-8 mm latis, infimis detlexis parallelibus, herba- 
ceis, costa excepta glabris et costa infra fere glabris; venulis utroque 
latere 2, superioribus plerumque liberis; fronde fertile 15 cm alta, 4 cm 
lata, acuminata, pinnis acutius auriculatis, cuspidato-acutis, supra
