lanceolate, beaked, many-nerved, glossy ; margins of the 

 upper half (not apex) largely serrate; tip truncate. Achenium 

 lanceolate. 



Hah. Half-concealed among low herbage, open grassy 

 plains at Tahoraiti, south of Daunevirke, County of Waipawa ; 

 1887 : W. C. 



Obs. This little species has pretty close affinity with C. 

 colensoi, Hook. f. It is, however, a smaller plant, differing in 

 several characters, particularly in its broader and flatter 

 leaves, its fewer and slenderer spikelets, broader and tri- 

 coloured glumes, with larger membranous margins, narrower 

 and beaked utricles, long scabrid styles and stigmas, and 

 narrow (not "orbicular") achenium (as shown in dissections 

 of C. colensoi— "Fl. N.Z.," tab. 63b). 



2. C. folyneura, sp. nov. 



Plant loosely tufted, branched below, spreading, light- 

 green. Culms erect, 7in.-9in. high, smooth, bluntly tri- 

 quetrous, leafy. Leaves sub-rigid, linear very acuminate, 

 8in.-9in. long, ^in. wide near base, flat, smooth, shining, 

 channelled, much striate (sub 22-nerved), sheathing ; sheaths 

 membranous, sub-truncate, bifid and sub-laciniate, coloured ; 

 ligule large, diagonal ; keeled, upper portion of keel scabrid ; 

 margins slightly recurved and finely serrulate, most so at tips ; 

 tips filiform, acute, recurved. Spikelets 5-6, erect, axillary, 

 bracteolate, rather distant, ^in. long, cylindrical, stoutish, 

 obtuse, the lowest peduncled; peduncle slender, rigid, lin. 

 long ; the top one wholly male, narrow, obovate ; the others 

 with few or no male flowers at their bases ; the lower 

 bracts long and leafy; the upper ones very narrow, short, 

 erect. Glumes broadly ovate, bifid, purple, closely reticu- 

 lated ; margins membranous and finely laciniate ; awned, awn 

 as long as and longer than the glume, green, rigid, sharply 

 and closely serrulate. Utricle longer than glume, sub-orbicu- 

 lar or broadly elliptic, 1 line long, turgid, smooth, shining, 

 convex on the outer side, slightly concave on the inner, some- 

 what beaked, bifid, pale-greenish below, dark purple-brown 

 above. Stigmas 3, short, pinkish, very scabrid. Anthers

Hab. Edges of streamlets, woods, south of Dannevirke, 

 County of Waipawa ; 1887 : W. C. 



3. C. longiacuminata, sp. nov. 



Plant large, dark-green, tufted with short surculi. Culms 

 stout, erect, 2ft. 9in.-3ft. high, leafy, smooth, angles obtuse; 

 bract-leaves long, the lowest longer than culm, 4 lines broad, 

 keeled, margins and keel finely and closely serrulate. Leaves 

 shorter than culm, same width, &c., as bracts, slightly rigid,
