AsPIDIUM PTEROIDES. 
Nephrodium pteroides, J. Smith in Hook, et Bak. Syn. Pil. 289. 
Baxter’s River ; Rev. S. Macfarlane. 
This has been identified by Mr. Baker, who through the direct facilities 
afforded him by the vast collections of ferns, brought together in more 
than half a century by Sir Will. Hooker, has become the most experienced 
among' the present pterilogist. 
Aspibium acutum. 
Schkuhr, Cryptog. Gewaschse, 32, t. 31. 
Fl}^- River; D’ Albertis. 
Sent also from New Ireland by the Rev. G. Brown. An allied larger 
species or perhaps merely variety with exauriculated pinnse and with sori 
remote from the edge inhabits also the banks of the Fly-River. 
Aspibium ramosum. 
Beauvois, Plore d’Oware, t. 91. 
Fly-River ; D’ Albertis. 
POLYPOBIUM ACROSTICHOIBES, 
B. Brown, Prodr. 146. 
Fly-River ; D’ Albertis. 
POLYPOBIUM IRREGULAUE. 
Presl, Reliq. Hsenk. i. 25, t. 4. 
Fly-River ; D’ Albertis. 
POLYPOBIUM LiNNA3I. 
Bory in Annal. des Scienc. Nat, v, 464, t, 12, 
Port Moresby; Goldie. Fly-River; D’Albertis. 
This was collected also at Makado (Duke of York^s Island) by the Rev. 
G. Brown. The segments of the fronds secede readily from the rachis 
like those of Acrostichum diynaroides, with which species to some extent 
this also agrees in habit. Not always easily separated from P. querci- 
folium (L. Sp. 1087). 
POLYPOBIUM HERACLEUM. 
Kunze in der Bot. Zeitung, vi. 1 1 7. 
Fly-River ; D’Albertis. 
The Papuan plant is slightly hairy on the under-page of the frond.
