Leaves all radical, on slender petioles 1–4 in. long; blade ½–1½ in. long, oblong or obovate, in small specimens sometimes entire, but usually pinnatifid with a very large terminal lobe and 1 or 2 pairs (rarely more) of small spreading lobes at its base. Flowering-stems 1–3, few-flowered, naked; pedicels slender, ½–1 in. long or more. Flowers large, white, sometimes nearly in. diam. Pods ¾–1 in. long, narrow-linear, spreading; style long and slender.

4. C. stylosa, ''D.C. Syst. Veg.'' ii. 248.—A tall rather coarse perfectly glabrous leafy branching herb 2–3 ft. high; erect or decumbent. Leaves 3–5 in. long, oblong-lanceolate or oblong-spathulate, entire or more usually minutely and remotely sinuate-toothed, sometimes lobed or pinnatifid at the base; uppermost sessile, auricled at the base; lower on long petioles. Racemes very long, 1–2 ft. Pedicels stout, short, spreading. Flowers small, white. Pods horizontally spreading, 1–1½ in. long, $1⁄12$ broad; style stout. Seeds red-brown, with a reticulate testa.—''Hook. f. Handb. N.Z. Fl. 12; Kirk, Students Fl.'' 27. C. divaricata, ''Hook. f. Fl. Nov. Zel.'' i. 13. Arabis gigantea, ''Hook. Ic. Plant.'' t. 259.

5. C. fastigiata, ''Hook. f. Handb. N.Z. Fl.'' 13.—Rootstock long, stout, tapering, often as thick as the finger, bearing at the top a rosette of densely crowded radical leaves Leaves 1½–3 in. long, linear- or lanceolate-spathulate, acute, sharply and deeply inciso-serrate, gradually narrowed into a broad flat petiole, thick and coriaceous, glabrous or with a few weak hairs on the margins. Cauline leaves similar, but smaller and less toothed. Flowering-stems usually several springing from the top of the rootstock among the radical leaves, simple or branched, 6–18 in. high. Flowers numerous, white, corymbose, about ⅓ in. diam. Petals ⅓ in. long, spathulate, on long claws. Pods erect or nearly so, straight or curved, acute at both ends, narrow-linear, 1–2 in. long, $1⁄15$–$1⁄12$ broad. Seeds
