completely and distinctly septate. Cymes terminal, sparingly branched, more or less contracted, usually of 3–8 fascicles, rarely more; bract at the base long, foliaceous, usually overtopping the cyme. Flowers 10–20 in each fascicle, greenish, about ⅙ in. long. Perianth-segments equal, lanceolate, acuminate. Stamens 6, about half the length of the perianth-segments. Capsule equalling the perianth or rather longer than it, narrow, prismatic, triquetrous, 1-celled, the placentas not very conspicuous inside the cells. Seeds ovoid-oblong, grooved and transversely rugose, apiculate at each end.—Hook. f. Handb. N.Z. Fl. 290; Buchenan Monog. Junc. 357. J. prismatocarpus, Benth. Fl. Austral. vii. 131 (in part). J. cephalotes, Hook. f. Fl. Nov. Zel. i. 263 (not of Thunb.).
North Island: Swamps from the Bay of Islands southwards to Wellington, not common. Sea-level to 2500 ft. November–February.
Also found in Australia and Tasmania. Bentham unites it with J. prismatacarpus, from which it appears to me to be abundantly distinct, as pointed out under that species.
13. J. lampocarpus, Ehr. Calam. n. 126.—Perennial, more or less densely tufted. Stems erect or ascending, rarely decumbent at the base, slender, terete or compressed, soft, leafy, 6–18 in. high. Leaves shorter than the stems, 3–9 in. long, 120–112 broad, linear-subulate, straight or curved, compressed or nearly terete, unitubular, strongly septate; sheathing base long and narrow, with 2 obtuse auricles at the tip. Cyme terminal, compound; branches slender, divaricate, bearing small 2–5-flowered heads at the tips and in the axils; lower bract much shorter than the cyme, leafy. Flowers small, 110–18 in. long, chestnut-brown. Perianth-segments equal, lanceolate, acute. Stamens 6, much shorter than the segments. Capsule exceeding the perianth, narrow, pyramidal, triquetrous, mucronate, reddish-brown, glossy, 1-celled. Seeds obovoid, reticulate.—Kirk in Trans. N.Z. Inst. vii. (1876) 378; Buchen. Monog. Junc. 376.
North and South Islands: From the Auckland Isthmus to Foveaux Strait, not uncommon in wet places. Sea-level to 3500 ft. November–February.
A common plant in many parts of the north temperate zone, but in the Southern Hemisphere apparently restricted to New Zealand. Perhaps not truly indigenous, although now widely spread, even in remote mountain districts.
14. J. scheuchzerioides, Gaud. in Ann. Sci. Nat. Ser. i. 5 (1825) 100.—Stems usually much branched below, often prostrate and rooting, 2–8 in. long or more, leafy throughout. Leaves strict, erect, 1–5 in. long, far exceeding the culms, narrow-linear, attenuated at the apex, compressed, striate, pale-green, soft and herbaceous, pith with transverse joints; sheathing base long and broad, mem-
