114 : Mount Cook district, T. F. C.; Central Otago, not uncommon, Petrie! Var. robusta: Nelson—Wairau Valley, T. F. C. Canterbury—Broken River basin, ''Enys! Kirk! Petrie! T. F. C.; Kowai River, Petrie!''

The distinguishing characters of this species lie in its stout rigid habit, almost terete branchlets, numerous often fascicled racemes of rather small flowers, and the turgid pod. Mr. Kirk's C. robusta cannot be separated except by the longer and proportionately narrower pod with a larger number of seeds, and is best kept as a variety.

8. C. subulata, T. Kirk, Students' Fl. 112.—A slender erect often leafy glabrous shrub 1-3 ft. high, with almost terete branches. Branchlets $1⁄20$–$1⁄10$ in. broad, compressed or plano-convex, strict and rigid, grooved or striated. Leaves 3-foliolate; leaflets oblong-obovate, retuse. Racemes laxly 3–6-flowered, one or several together; pedicels silky or almost glabrous, shorter than the flowers. Calyx campanulate; teeth minute, acute. Standard broader than long, about equal in length to the wings and keel. Pod $1⁄4$–$3⁄8$ in. long, turgid, subulate, acuminate; beak short, stout, straight. Seeds 1–4, usually 2.

9. C. virgata, T. Kirk, Students' Fl. 112.—An erect rigid glabrous shrub 3–4 ft. high, branched from the base. Branchlets numerous, terete or plano-convex, grooved. Leaves not seen. Racemes few, 3–5-flowered, lax; pedicels and rachis glabrous or puberulous. Calyx campanulate, glabrous; teeth short, acute. Standard broader than long, equalling the wings and exceeding the keel. Pods (not quite ripe) ⅓ in. long, oblong, turgid, narrowed below; beak short, straight, subulate. Seeds 1–3.

10. C. diffusa, ''Petrie in Trans. N.Z. Inst.'' xxv. (1893) 272.—A small erect or spreading glabrous much-branched shrub 1–2 ft. high. Branchlets slender, $1⁄20$–$1⁄15$ wide, compressed or plano-convex or almost terete, striate. Leaves not seen. Racemes numerous, short, 3–6-flowered; pedicels shorter than the flowers. Calyx cup-shaped, mouth ciliolate; teeth minute, sometimes hardly evident
