206 involucral bracts numerous, ovate or lanceolate. Calyx-teeth obsolete. Petals oblong, acute, with a short incurved tip. Fruit oblong or linear-oblong, usually tapering to the apex, slightly compressed laterally; carpels subterete, with 5 equal obtuse ribs, the 2 lateral ones close to the commissure. Vittæ 1 in each furrow and 2 on the commissural face. Seed nearly terete, but grooved on the commissural side.

1. O. andicola, Endl. Gen. Plant. 787.—Exceedingly variable in stature and habit, 2–24 in. high, either stemless with radical leaves and scapes or much branched from the base, with short or long slender sparingly divided leafy stems, glabrescent or tomentose or pilose. Leaves usually numerous, mostly radical, 1–6 in. long, linear-oblong, pinnate or 2-pinnate; leaflets pinnatifid or variously toothed or incised. Peduncles several, usually springing from the rootstocks, but in the branched varieties axillary as well, longer or shorter than the leaves, glabrescent or pilose, especially towards the tip, where the hairs are usually reversed. Umbels few- or many-flowered; involucral bracts 6–8, ovate to linear. Flowers at first sessile, but pedicels lengthening as the fruit ripens, often unequally so. Fruit linear- or ovate-oblong, glabrous or more or less densely pubescent.—''Hook. f. Fl. Antarct.'' ii. 288, t. 101; ''Benth. Fl. Austral.'' iii. 377; Kirk, Students' Fl. 197.
