CoLEXso. — Description of new Cryptogamic Plants. 61 



stout flagellas descending from middle of stem. Leaves closely 

 imbricate, wavy, yellowish-green, broadly sub-obloug-ovate, 

 entire, sometimes minutely, distantly, and irregularly denticu- 

 late. Stipules narrow reniform-oblong, contracted at base, 

 sub-amplexicaul, margins irregular, slightly and distantly 

 toothed. Cells large, orbicular, dotted, with minute cellules 

 in their angles. Perianth basal, shortly peduncled, green, 

 campanulate ; mouth lacinio-ciliate, liexuous ; involucral 

 leaves — inner, small, entire ; outer, erect, trifid. 



Hab. On rotten wood, among mosses, forming spreading 

 patches, forests. Great Barrier Island, Frith of Thames ; 1888 : 

 Mr. C. P. Winkehnann. 



8. C. lingulata, sp. nov. 



Stem procumbent, creeping, simple, straight, lin.-2iin. long, 

 3 lines wide (in the larger specimens), spreading and growing 

 over each other, stoutish, brown, shining, piunatifid ; lobes 

 (or leaflets) of two sizes on stem, the lower being much 

 smaller; cut nearly to rhachis (sometimes distinct), adnate, 

 scarcely decurrent, alternate and sub-opposite, sub-imbricate, 

 oblong-lingulate, entire, both margins nearly straight, the 

 lower slightly oblique; tips rounded, very obtuse, with occa- 

 sionally a very minute microscopical tooth or horn at the 

 anterior apical corner ; the segments in the small branches 

 having their tips more truncate, and often minutely 2-horned. 

 one at each of the outer angles ; pale whitish-green. Cells 

 large, compact, sub-quadrilateral, with free, thickish, dark 

 rings within them. Stipules rather large, spreading, distant, 

 bifid; tips acuminate, acute; sinus broad, the base rounded, 

 each lobe 3-4 denticulate-ciliate ; generally placed centrally 

 under the upper lobe of a quasi pair of leaves, and sometimes 

 at their junction on stem. Cells large, orbicular, clear, with 

 a thick bunch of long flexuous white rootlets at base of each 

 stipule. Perianth peduncled on ventral side near base, 4-5 

 pairs opposite and near each other, short, stout ; perianth 

 green, lobes long acuminate, laciniate, curved. 



Hah. On the ground, damp shady forests near Dannevirke, 

 County of Waipawa ; 1888 : W. C. 



Obs. A species having close affinity with C. siipiinis. 

 Hook. f. and Tayl., and also with C. poluclachis, Mitt. This 

 peculiarity of its leaves being biformed, and bidentate on the 

 smaller (or younger) branches, has also been noticed to obtain 

 in the allied form C. supinus — -viz. : " in ramis junioribus folia 

 abnormalia varie bidentata" ("Fl. Nov. Zeal.," vol. ii., p. 142). 



9. C. epiphyta, sp. nov. 



Plant small, delicate, simple, and forked, fin.-lin. long, 

 1 line wide, pale-green. Leaves close, scarcely imbricate.
