1. C. Enysii, T. Kirk in Trans. N.Z. Inst. xvi. (1884) 379, t. 30.—A much-dwarfed depressed excessively branched glabrous plant, forming dense patches 1–2 in. high; stems and lower branches thick and woody, matted. Branchlets small, ⅓–¾ in. long, 1/251/10 in. broad, erect or suberect, compressed, thin, striate. Leaves of young plants orbicular, emarginate. Flowers minute, 1/61/4 in. long, solitary or in 3–6-flowered fascicles or racemes; pedicels slender, usually silky. Calyx carapanulate; teeth short, acute. Standard with a narrow claw; wings as long as the keel. Pod 1/51/3 in. long, compressed, ovate-orbicular, often oblique, sometimes obliquely deltoid; replum incomplete; beak stout, broad at the base, recurved. Seed usually 1, rarely 2–3.—Students' Fl. 108.

Var. orbiculata. Kirk, l.c.—Larger and stouter, 2–4 in. high; branchlets 1/6 in. broad. Pods with rugulose valves.—C. orbiculata. Col. in Trans. N.Z. Inst. xxii. (1890) 459.

North Island: South-eastern base of Ruapehu, Kirk! Var. orbiculata: Rangipo Desert, H. Hill! Kirk! Petrie! South Island: Broken River, Enys! Kirk! Ashburton Mountains, Potts; Maniototo Plain, Petrie! Var. orbiculata: Mount Ida, Petrie! 1500–3000 ft. December–January.

A most distinct and remarkable species, apparently rare and local. The pod dehisces by one of the valves separating from the replum down one side, but remaining attached at the tip and other side.

2. C. uniflora, T. Kirk in Gard. Chron. (1884) i. 512.—A much-dwarfed slender matted plant, forming large patches; stems often subterranean, putting out slender branches 1–2 in. high. Branchlets very narrow, 1/301/20 in., thin, compressed, glabrous, sometimes almost herbaceous. Leaves not seen. Flowers solitary, ⅓ in. long, purplish-red; peduncles very long and slender, almost capillary, glabrous or puberulous, bracteolate about the middle. Calyx campanulate, glabrous or silky; teeth short, broad, acute. Standard broad, with a short broad claw; wings shorter than the keel. Pod ⅓–½ in. long, linear-oblong; valves slightly wrinkled; beak straight or oblique. Seeds 2–6.—Kirk in Trans. N.Z. Inst. xvi. (1884) 379; Buch. l.c. 394. C. Suteri, Col. in Trans. N.Z. Inst. xxiii. (1891) 383.

South Island: Canterbury—Lake Grassmere, Lochnavar, Poulter River, Enys! Otira River, Cockayne! Mount Cook District, Suter! T. F. C. Otago—Waitaki Valley, Buchanan! Lake Hawea, Petrie! 1000–3000 ft. December–January. Probably not uncommon, but easily overlooked.

8. C. nana, Col. ex Hook. f. Handb. N.Z. Fl. 49.—A dwarf rigid glabrous plant, forming broad matted patches. Branchlets 2–4 in. long, 1/61/2 in. broad, thin, much flattened, strict, erect,
