Notes on Some New Zealand Plants and Descriptions of New Species (No. 2). By G. Simpson By J. Scott Thomson [Read before the Otago Branch, November 11, 1941; received by the Editor, November 17, 1941; issued separately, June, 1942.] Ranunculaceae. Ranunculus lobulatus (T. Kirk) Ckn. Achenes numerous, crowded in a broadly conical dark green head to 1 cm. diam. or slightly more, half obovate in outline, compressed, 3 mm. long including the style, keeled at the back, extended into a straight or oblique subulate beak as long as the achene. Our specimens in the Herbarium, Plant Research Bureau, Wellington, are from plants in cultivation collected on Mount Fyffe, Marlborough, at 720 m. altitude. Ranunculus novae-zealandiae Petrie. Petrie described a “glabrous fleshy glaucous plant” with the leaf blades “ternately divided” and “ripe achenes not seen.” On the Rock and Pillar Range—the type habitat—and on the Garvie Mountains, the leaves are invariably dark green with the veins sunken on both surfaces; petioles and scapes purplish, spotted with pale yellow-green, leaf blades 3–5 foliate, or 7 foliate on larger plants; lower segments sessile, the following pair in larger leaves petiolate, the upper ones sessile and the terminal one again more or less distant. Achenes in a rounded head ± 6 mm. diam., turgid, half-obovate in outline, rather more than 1 mm. diam., obscurely keeled at the back, with a short, stout, straight or upturned, subulate beak. —– var. repens nov. Herba repens, rhizomatis crassis, albis, mollibus, instructa; alioqui ut in typo. Almost exactly as the type but spreading widely by stout, soft, white underground stems, which occasionally arch above the ground. Habitat: Debris at Blue Lake, Garve Mts., 1230 m. altitude. Type specimens in the Herbarium, Plant Research Bureau, Wellington. The 3 foliate leaves of small or reduced plants of the species are curiously unlike those of more vigorous growths, and individual plants, differing only in the development of their leaves, might well be mistaken for distinct varieties. Poppelwell (1915, p. 128) recognised 2 forms on the Garvie Mountains, one with 5 petaled flowers and one 8–10 petaled. The 5 petaled flowers appear to be those of var. repens, and 8–10 petaled flowers those of the usual form of the species on this range.
