Colenso. — On new Cryptogams. 247 



inches high, 3 lines wide, simple, forked at middle, branched at 

 top into 4-5 short branchlets ; tips recurved. Leaves alternate, 

 rather distant, not imbricate, broadly oblong or somewhat sub- 

 orbicular, wavy and concave, 2 lines long, apex much rounded ; 

 the ventral margin and apes distantly and irregularly cilio-laci- 

 niate ; the dorsal margin entire, base slightly oblique and decur- 

 rent on stem. Cells orbicular, crowded, smaller at margins, 

 their walls double, thickened, with minute cellules. Perianths 

 few, scattered, axillary between branches, sessile, obconic-cam- 

 panulate, 1 line long, compressed ; apex rounded ; lips ciliated, 

 extending down on one side ; dark-green. 



Hab. On trees and logs, in woods with the preceding 

 species, P. trispicata; 1887: W.C. 



7. P. subfasciculata, sp. nov. 



Plant dendroid, 2-3 inches high ; rhizome creeping, long, 

 wiry ; stems slender, erect, sub-rigid, dark coloured, leafy from 

 base, much branched ; branches alternate, bipinnate, long, 

 diffused, irregular, (often a long branch at right angles from 

 main stem,) branchlets opposite, sometimes 4-6 short ones 

 nearly together at top of branch, sub-fasciculate. Leaves light- 

 green, sub-opposite, rather distant, scarcely overlapping at 

 extreme margins, somewhat semi-lunar or sub-rhomboid-dimi- 

 diate, apex broad, rounded ; those on main stems and branches 

 2 lines wide, on branchlets much smaller ; ventral margin much 

 curved and, with apex, laciniate toothed, sub 12 teeth, long, 

 acute, irregular in size, distant, longer and closer at apex, few 

 or none at base, basal margins slightly impioging, decurrent on 

 stem, sinus between teeth broad and rounded ; dorsal margin 

 entire, oblique, slightly decurrent on stem. Involucral large, 

 erect, apex much laciniate. Cells opaque, sub-orbicular, double- 

 walled with minute intermediate cellules. Perianth rather 

 small, dark-green, sessile, axillary between branchlets, broadly 

 cuneate or sub-campanulate, slightly compressed ; mouth large; 

 lips rounded, cilio-laciniate ; teeth irregular, larger in centre, acute, 

 many-celled. Cells similar to those of leaves but more oblong. 



Hab. On logs and trunks of trees, wet woods near Danne- 

 verke, County of Waipawa ; 1887 : W.C.
