Aneura orbiculata, sp. nov. 



Plant large, spreading, growing flat on rotten logs and over small 

 mosses and Hepatica, 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 \ 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 3-5 together subfasciculate but 

 diverging (as in prickly pear). Fruit stalk (seta) 1J inches long, white, 

 shining, finely striated, striae 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, laciuiate, 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 fine 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: 

 W.C. 



Obs. — A species having pretty close natural affinity with A. orbiculata, 

 niihi {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 37. Fimbriaria, Nees. 

 Fimbriaria gracilis, sp. nov. 



Plant gregarious ; frond single, procumbent, 3-7 lines long, l£ lines 

 wide, linear-oblong or linear-obovate, sinuate, incurved, edges thin and finely
