dense, corymbose, probably elongating in fruit. Flowers usually numerous, 
rather large, 4-+in. diam., white, pink, or purple. Sepals sometimes 
purplish at the tip. Stigma broad, almost sessile. Ripe fruit not seen; in 
an immature state the pods are crowded, very short and broad ; style almost 
wanting. C. hirsuta Linn. var. subcarnosa Hook. f. Fl. Antarct. i (1844)

AUCKLAND AND CAMPBELL Istanps: Not uncommon in stony debris or in moist 
grassy places, Hooker, 1. Kirk, Cockayne! B.C. Aston! J. S. Tennant! R. M. Laing ! 
Has been recorded from Macquarie Island on the authority of A. Hamilton, but I have 
seen no specimens. 
Differs from any of the forms of C. hirsuga, under which it was placed by Hooker, 
in the stout and fleshy habit, perennial rhizome, large often coloured flowers, short and 
broad pods, and almost sessile stigma. It is much nearer to the southern C. glacialis, 
with which it was united by Schulz in his monograph of the genus. It also occurs in 
Chile, Fuegia, Falkland Islands, and Kerguelen Island. 
3. ©. corymbosa Hook. f. Fl. Antarct. i (1844) 6.—Small, wiry and 
fragile, branched from the base, 14-3 in. high, sparingly clothed with spread- 
ing hairs or quite glabrous. Root perennial. Stem short, decumbent or 
ascending ; branches slender, almost filiform, spreading and flexuous, 
sparingly leafy. Leaves few, long-petioled, 1-2 in. long, pinnately divided ; 
leaflets 3-5, petiolulate, rounded or cordate or broadly ovate, the terminal 
one much the largest, sometimes in. diam., the lateral usually remote. 
Flowers minute, ;4,in. diam. or less, irregularly fascicled or corymbose, 
or solitary and axillary. Petals twice the length of the sepals. Pod 
narrow-linear, strict, erect, flat, Jin. long; seeds 10-15.—-Ic. Plant. (1844)

| AUCKLAND AND CAMPBELL IsLANDS: Port Ross, J. S. Tennant ! Cockayne ; Camp- 
bell Island, turfy ground near the sea, Hooker, R. M. Laing! Macquarie Isianp : 
Apparently common, A. Hamilton (1894), H. Hamilton (1912-13)! Also recorded from 
Orange Harbour, Fuegia, but I have seen no specimens from the mainland of New 
Zealand. 
In addition to the ordinary inflorescence, C. corymbosa produces very curious cleisto- 
gamic flowers, first noticed by Dr. Schulz during an examination of Hooker’s specimens, 
collected 80 years ago. Some observed by myself on one of Tennant’s specimens were 
barely visible to the unaided eye. There were 4 scale-like sepals, no petals, and 4 small 
stamens. ‘The ovary was short, conical, 2-celled, each cell containing 2-6 ovules. 
Similar cleistogamic flowers have been described from the South American C. chenopodi- 
folta. 
4. ©. depressa Hook. f. Fl. Antarct. i (1844) 6.—- Perennial, small, 
stemless, glabrous or nearly so, forming rosettes 1-2in. diam. Leaves 
numerous, crowded, spreading, or the upper suberect, simple, oblong- 
obovate or obovate spathulate, rounded at the apex, narrowed at the 
base into a petiole longer or shorter than the blade, shortly lobed with 
the lobes rounded, 3-1 in. long including the petiole. Flowers small, 4 in. 
long, either solitary on 1-flowered scapes, or forming a few- or many- 
flowered corymbose raceme. Pods erect, 4-1 in. long, style short.—
