their fertilisation is doubtless effected. I have much pleasure in dedicating the species to Mr. T. F. Cheeseman, F.L.S., who has done much to elucidate the New Zealand species of the genus. I have a form of this species from Mount St. Bathan's (4,500 feet); and Mr. G. M. Thomson informs me that he has gathered the same on the Rock and Pillar Range at an altitude of 4,000 feet. Carix berggreni, n. sp. Small, loosely tufted, reddish-brown. Culms very short, 1 ¼–2 inches long, flattened above, shorter than the leaves, and enclosed to the base of the head by thin broad sheathing bases. Leaves red-brown, 2–3 inches long, flat linear, of uniform width throughout the blade, obtuse, not serrate, finely and closely striate; bases paler, membranous, sheathing, twice as broad as the blade. Spikelets 3, unisexual; two lower female, uppermost wholly male, approximate, stout, each 3 lines long, on short slender pedicels; bracts leaf-like, sheathing, diminishing in the upper spikelets. Glumes broadly-ovate, shorter than the utricles, membranous, obtuse, rarely mucronate, entire, 1-nerved, with dark-brown streaks and blotches. Utricles turgid, bi-convex, elliptic-oblong, not beaked, shortly bifid, spreading, very faintly nerved, dark-brown or black above, elsewhere green. Branches of the style, 2. Fruit, 3-angled. Hab. Mount Pisa Range, at the head-waters of the Luggate Creek, 4,000 to 5,000 feet. This is a most distinct species. It is most nearly related to C. uncifolia, Cheeseman, but its short red-brown obtuse ensiform leaves readily distinguish it from all its congeners in New Zealand. The male spikelet is somewhat larger than and not so stout as the female ones. Named in honour of Dr. Sven Berggren, of Upsala University, who has described and figured several New Zealand species of the genus. Carex kirkii, n. sp. Small, densely tufted, grass-like; forming low tussocks 1–2 ½ feet in diameter. Culms ½–1 inch long, very slender, much shorter than the leaves, and enclosed in their sheathing bases. Leaves 3–5 inches long, filiform, involute, slightly striate, pale-green, with short broad membranous sheathing bases. Spikelets 3–5, forming a compact ovoid head 6–9 lines long, sessile, closely approximate, female below, male above, few-flowered; bracts variable, the lowermost usually leaf-like, the upper glume-like, all shortly sheathing at the base.
