striate; margins ciliate; 2 or 3 outer empty. Stamens 3. Style-branches 3. Nut almost sessile, ovoid, trigonous, puberulous, pale-chestnut, narrowed upwards into a rather stout pyramidal beak.
North Island: Auckland—Ohaeawai and Taheke, Berggren! Puhipuhi Forest, Kirk! Maungatapere, Carse! September–November.
Apparently a very local plant, not yet found outside the Bay of Islands and Whangarei Counties.
3. C. articulatum, R. Br. Prodr. 237.—Stems tall and stout, terete, transversely septate, 3–6 ft. high. Leaves long, almost equalling the stems, terete, the transverse septa usually very distinct; sheaths large and long, pale; tip subulate, acute, pungent. Panicle large, lax, terminal, much branched, drooping, 9–18 in. long; branches numerous, closely placed; bracts sheathing, the lowest with a terete septate lamina ½–1½ in. long. Spikelets excessively numerous, rich red-brown, ⅙ in. long, 2–4-flowered, but usually only one flower is fertile. Glumes 4–7, ovate or ovate lanceolate, acuminate, keeled, membranous, puberulous, the 2 outer empty. Stamens 3. Style-branches 3. Nut broadly obovoid, trigonous with the angles thick and corky, red-brown; beak short, umbonate.—Hook. f. Fl. Nov. Zel. i. 276; Handb. N.Z. Fl. 304; Benth. Fl. Austral. vii. 403. Baumea loculata, Boeck. in Linnæa, xxxviii. (1874) 243. Gahnia articulata, F. Muell. Second Census Austral. Pl. 216.
North Island: Margins of lakes and ponds from the North Cape to Taupo and Hawke's Bay, not uncommon. Sea-level to 1800 ft. November–January.
Also in Australia, New Caledonia, and the New Hebrides. Small states sometimes have the stems and leaves obscurely septate.
4. C. glomeratum, R. Br. Prodr. 237.—Stolons creeping, clothed with pale striated scales. Stems tufted, terete and rushlike, slender, rather soft, 1–3 ft. high. Leaves few from the base of the stem, long, terete, with acute subulate tips. Panicle contracted, 3–10 in. long; lower branches distant, usually long and narrow, erect; upper closer together, shorter and broader; primary bracts large and sheathing, almost spathaceous. reddish-brown. Spikelets numerous, fascicled, red-brown, ⅙–⅕ in. long, ovate-oblong, 2–3-flowered, 1 or rarely 2 of the flowers fertile. Glumes usually 5, ovate, acuminate, membranous, striated; margins ciliate; 2–3 outer ones empty. Stamens 3. Style-branches 3. Nut elliptic-oblong when mature, obtusely trigonous, smooth and polished, reddish or reddish-yellow; tip tumid, acute, pubescent.—Hook. f. Fl. Nov. Zel. i. 275; Fl. Tasm. ii. 94; Handb. N.Z. Fl. 304; Benth. Fl. Austral. vii. 404. Schœnus rubiginosus, Forst. Prodr. n. 493. Fuirena rubiginosa, Spreng. Fl. Hal. Mant. i. 29; A. Cunn. Precur. n. 271; Raoul, Choix, 40.
