19. C. Gaudichaudiana Kunth Enum. ii (1837) 417.—Rhizome stoloni- 
ferous. Culms slender, strict, trigonous, smooth or slightly scabrid above, 
very variable in height, usually from 4 to 12in., but sometimes dwarfed 
to 1 or 2in., at other times attaining 18in. Leaves shorter or longer 
than the culms, narrow, flat, grassy, so-~zim. broad. Spikelets 3-65, 
rarely more or fewer, sessile or the lowest very shortly stalked, erect, close 
together or a little remote, }-?in. long; terminal one (and sometimes a 
smaller one near its base) wholly male, linear or linear-oblong; the rest 
temale, often with a few male flowers at the top, oblong, cylindric; bracts 
long and leafy, the lowest usually exceeding the inflorescence. Glumes 
oblong or obovate-oblong, obtuse or very shortly mucronate, shorter than 
the utricle, dark-purple or purplish-black, usually with a narrow pale midrib 
and margins. Utricle narrow-ovate to orbicular-ovate, much compressed, 
conspicuously nerved almost to the apex, green spotted with brownish-red 
when ripe, upper portion minutely granular-papillose; beak very short, 
almost wanting, entire or minutely 2-toothed. Styles 2. Nut broadly

NortH AnD SourH Istanps: Moist places in mountain districts from the Upper 
Waikato southwards, rarer in the lowlands. Sea-level to 4500 ft. November-— 
February. Var. humilior : Not uncommon on the mountains of Nelson, Canterbury, 
and Otago, 7’. F. C., Cockayne ! Petrie ! 
Also in Australia and Tasmania, and very closely allied to the almost cosmopolitan 
C. vulgaris Fries, differing chiefly in the more compressed and conspicuously nerved 
utricles. |

vs-}in. broad; margins scabrid above. Spikelets 4-8, erect, 1-3 in. 
long; terminal 1-3 male, usually approximate, sessile, very slender, cylin- 
dric; the remainder female, usually with a few male flowers at the top, 
the upper sometimes geminate, sessile or shortly stalked, the lower solitary,
