Leaves alternate, imbricate, $1⁄5$–$1⁄3$ in. long; petiole half the length, very broad, membranous, closely sheathing the stem; blade much dilated, broader than long, closely appressed, concave, coriaceous, 3–5-partite to the middle, upper surface furnished with several long stiff bristles; lobes spreading, oblong, acute or apiculate; margins quite entire, much thickened. Umbels almost concealed amongst the uppermost leaves, shortly pedunculate, 3-flowered. Involucral leaves linear, subacute. Calyx-teeth acute. Fruits ovoid, terminated by the elongated styles; carpels slightly compressed, convex on the back, 5-ribbed, contracted at the commissure.—''Phil. Trans. Roy. Soc.'' clxviii. 20; Kirk, Students Fl. 191

2. A. exigua, Benth. and Hook. f. in Gen. Plant. i. 875.—Small, stemless, forming little tufts ½–2 in. diam. Leaves numerous, crowded at the top of a short and stout rhizome, ¼–¾ long; petiole long, stout, sheathing at the base; blade minute, $1⁄6$–$1⁄4$ in. diam., ovate-orbicular, obscurely 3-lobed or crenate, cordate or rounded at the base, coriaceous, minutely papillose above; margins recurved. Scapes shorter than the leaves, 3–8-flowered; involucral leaves linear, obtuse, rounded at the base. Fruit $1⁄12$ in. long, almost tetragonous; carpels 5-ribbed, rounded at the back.—Kirk, Students' Fl. 191. Pozoa exigua, ''Hook. f. Handb. N.Z. Fl.'' 87.

3. A. reniformis, Benth. and Hook. f. l.c.—Bright-green, rather fleshy, perfectly glabrous. Rhizome slender, creeping, often emitting short stolons. Leaves tufted, ⅓–¾ in. diam., orbicular or reniform, crenate-lobed, coriaceous or almost membranous; petioles rather stout, 1–2 in. long, sheathing at the base; stipules acute or acuminate, quite entire. Umbels 3–8-flowered, on rather stout peduncles much shorter than the leaves; involucral bracts linear, obtuse, membranous. Fruit $1⁄8$ in. long, linear-oblong, tetragonous, rather longer than its pedicel; carpels obscurely 5-ribbed.—Kirk, Students' Fl. 191. Pozoa reniformis, ''Hook. f. Fl. Antarct. i. 15, t. 11; Handb.
