202 6. A. hydrocotyloides, Benth. and Hook. f. l.c.—Perfectly glabrous, stout, often densely matted. Root long and woody. Stems creeping and rooting at the nodes and putting up tufts of leaves, the runners sometimes 6 in. long or more. Leaves numerous, crowded, ¼–⅔ in. diam., orbicular or orbicular-reniform, very thick and coriaceous, 3–5-foliolate or -partite; leaflets sessile, sometimes overlapping, broadly obovate-cuneate, bluntly 3–5-lobed or -crenate at the tip; margins thickened; petioles stout, ½–1½ in. long; stipules narrow, entire or ciliate. Peduncles variable in length, solitary from the nodes of the stem or 2–4 at the top of a leaf-bearing scion. Umbels 4–15-flowered; involucral bracts linear, obtuse. Fruit linear-oblong, tetragonous, usually shorter than the pedicel; carpels 5-ribbed.—Kirk, Students' Fl. 192. Pozoa hydrocotyloides, ''Hook. f. Handb. N.Z. Fl.'' 88.

7. A. pallida, T. Kirk, Students' Fl. 193.—Pale-green, perfectly glabrous, smooth and shining. Rhizome creeping, leafy at the joints, and emitting creeping stolons. Leaves numerous, crowded, ⅓–¾ in. diam., orbicular or reniform, usually flaccid and membranous, rarely subcoriaceous, 3-foliolate or rarely 3-partite; leaflets obcuneate, 3–6-lobed at the tips; petioles slender, 1–3 in. long; stipules laciniate. Peduncles usually shorter than the leaves, either bearing a single terminal umbel with a 3–4-lobed leaf at its base, or with 2–3 long-stalked secondary umbels springing from the base of the primary one; sometimes the secondary umbels develop 1–2 tertiary ones in like manner. Umbels 4–12-flowered; involucral leaves linear, obtuse. Pedicels longer than the linear-oblong obtusely 4-angled fruits; carpels 5-ribbed.—Pozoa pallida, ''Kirk in Trans. N.Z. Inst.'' x. (1878) 419.

8. A. nitens, ''Petrie in Trans. N.Z. Inst.'' xxv. (1893) 270.—Small, slender, perfectly glabrous, smooth and shining, densely matted. Rhizomes creeping, much branched and interlaced. Leaves few, minute, $1⁄6$–$1⁄3$ in. diam., 3-foliolate or 3-partite; leaflets sessile or shortly stalked, oblong-ovate to linear-obovate, obtuse or acute, entire or obscurely 2–3-toothed, rather thin, perfectly glabrous; petioles slender, ½–1½ in. long. Peduncles as long or longer than
