Descriptive Notes on Papuan Plants, 
this occasion as an additional Papuan Aspidium (A. neriiforme, Sw. 
Sjn, Fil. 42), according* to Hook, et Bak. Syn. Fil. second edit. 302, 
0. museefolia, Kunze in Metten. Filic. Ind. 240, stands also on record 
from New Guinea, according* to Miq. Annal. i. 240, 
Adiantum lunulatum, 
Burmann, Flor. ludic. 235. 
Darnley’s Island; Rev. S. Macfarlane. 
Davallia elegans. 
Swartz Sjnops. Felic. 132,

Asplenium Scolopendropsis. 
Entirely glabrous ; steins creeping and rooting ; fronds simple, thinly 
chartaceous or almost membranous, elongate narrow-lanceolar, more or 
less sinuate-denticulate, gradually narrowed into a long wingless stipes ; 
veins simple or consisting of two branches, prominent, extending in 
almost parallel lines to the edge ; sori broad, in pairs, traversing the 
whole width of the frond from the stout midrib to the margin ; the 
indusia of each pair touching each other with their edge, but disunited 
from the commencement; sporangia of each indusium separated from 
those of the other in each pair by an ample empty interstice. 
In the South-East pai’t of New Guinea; D’ Albertis. 
Rootlets, so far as seen, distant and not much branched, either very 
short or extending to simple wiry fibres sometimes over a span long. 
Fronds |-1 J foot long, to about 1 inch broad, very gradually acumi- 
nated ; the margin often wavy and with rather distant and irregular 
denticulations ; veins very spreading. The paired sori somewhat distant 
from each other ; the very tender indusia of each pair covering a width 
of about one line or rather more. 
This remarkable Asplenium invalidates still more the limits of Scolo- 
pendrium as a genus, the reunion of the latter with the former becoming 
almost unavoidable. The sori of the typic Scolopendrium vulgare 
(Smith in Memoir. Acad. Roy. des Scienc. Turin, v. 421, t. 9, f. 2) are 
however at the early state of growth covered by indusia, which overlap 
each other, the sporangia within forming a crowded uninterrupted mass. 
Specific distinctions to separate this new species from the ordinary 8colo- 
pendrium are further easily derived from the total absence of a scaly
