1. R. sphærocarpa, ''Desv. Journ. Bot.'' i. (1808) 327.—Perennial, densely tufted. Stems many, crowded, erect, terete, 4–9 in. high. Leaves several, equalling or exceeding the stems, sheathing at the base, erect, rigid, pungent, polished, channelled in front. Flower solitary, terminal, ¼ in. long; bracts 2, the lowest foliaceous, twice as long as the flower or more, upper small, scarcely equalling the flower. Perianth-segments nearly equal, linear-oblong, acute. Stamens shorter than the segments; filaments linear; anthers longer than the filaments, connective unguiculate. Capsule large, equalling or exceeding the perianth, ovoid-globose, mucronate, hard and almost woody, dark-chestnut, smooth and shining. Seeds obovoid, inappendiculate.—R. magellanica, ''Hook. f. Fl. Antarct. i. 81; Handb. N.Z. Fl. 291; Buchen. Monog. Junc.'' 70. Juncus magellanicus, ''Lam. Encycl.'' iii. 266.

2. R. gracilis, Hook. f. Fl. Antarct. i. 83, t. 47.—Perennial,densely tufted. Rhizome stout, horizontal or inclined. Stems numerous, crowded, erect, terete, smooth, 6–12 in. high, base with several pale or dark fulvous sheaths. Leaves 1–3, from slightly longer to 2 or even 3 times as long as the stems, slender, terete, rigid, grooved in front. Flower large, solitary, terminal, ½–¾ in. long; bract solitary, very small, $1⁄10$ in. long, entire or 2-lobed. Perianth-segments linear-subulate, pale-chestnut, shining, the inner conspicuously shorter. Stamens 6, much shorter than the segments; filaments very short, broad and flat; anthers linear, 3 or 4 times as long as the filaments, connective unguiculate. Capsule
