Aneura orbiculata, sp. nov. 
Plant large, spreading, growing flat on rotten logs and over small 
mosses and Hepatice, in irregular oblong patches of 8-10 inches, adhering 
strongly ; thickish, glabrous, light green, branches short effigurate, loosely 
imbricate, lobes 4-8 lines wide, orbiculate in outline, deeply crenate, hyaline 
at edges, spongy underneath with numerous short obtuse semi-rootlets. 
Calyptra 4 inch long, stout, cylindric, fleshy, greenish-white, lacerate at top, 
top and edges disposed in minute tuberculated lumps, sparingly setose, hairs 
light-brown, more thickly set at top, some 8-5 together subfasciculate but 
diverging (as in prickly pear). Fruit stalk (seta) 1} inches long, white, 
shining, finely striated, stri® twisted. Capsule large, 2 lines long, brown, 
oblong-lanceolate, splitting crosswise ; valves spreading, pencilled at tips; 
elaters cohering. 
Hab. In wet shady woods, between Norsewood and Danneverke, Wai- 
pawa County, 1876, etc. ; in fruit, April, 1883: W.C. 
Obs.—A very handsome plant, but rarely found in fruit; without fructi- 
fication it might well be taken for an Anthoceros. 
Aneura imbricata, sp. nov. 
Plant spreading, flat, in patches of 4-6 inches, effuse, adhering pretty 
closely, sub-membranous, brittle, glabrous, green; branchlets or compound 
sub-foliaceous scales very numerous, irregular, laciniate, semi-convex, imbri- 
cated, ultimately much overlapping, lobes 3-4 lines broad, sub-orbicular in 
outline, margins sinuate, waved, and crisped, largely crenate, translucent, 
with very many short whitish-brown filiform rootlets issuing in pencils 
beneath, from middle of scales, and strongly adhering to those below; 
calyptra whitish-brown, erect, 4-6 lines long, cylindrical, stout, 1 line dia- 
meter, glabrous, having a broadly gibbous base; mouth bifid, slightly toothed 
and tuberculated with a few small scattered tubercles ; capsule not seen. 
Hab. On soil and on rotten logs, on the immediate low sides of deep 
water-courses, ravines, dark shaded woods, near Norsewood, October, 1883: 
Obs.—A species having pretty close natural affinity with 4. orbiculata, 
mihi (supra), but very distinct; their differences, however, are better and 
far easier seen in comparing the two plants while fresh, than can be 
described in words. Some allowance must be made for description of 
calyptra, as those seen (several specimens) were more or less slightly 
damaged through recent heavy rains flooding the channels where they grew. 
Genus 87. Fimbriaria, Nees. 
Fimbriaria gracilis, sp. nov. 
Plant gregarious; frond single, procumbent, 8-7 lines long, 1} lines 
wide, linear-oblong or linear-obovate, sinuate, incurved, cdges thin and finely
