18. R. Novae-Zelandiae, PetHe in Trans. N.Z.I, xxvi. (1893) 267. 

 StemJess, glabrous. Rootstock rather stout, clothed with the bases of old 

 petioles; rootlets thick. Leaves on flattened petioles, iiii.— lin. long, sheathing 

 at the base ; blade f in.— lin. long or more, 3-foliolate, slightly coriaceous ; the 

 lower leaflets usually sessile, the upper distant, petiolulate, more or less deeply 

 divided into three 3-lobed crenate segments. Scapes 1—3, naked, 1-flowered, 

 lin.— 2in. long. Sepals 5, oblong, shorter than the petals, often deflexed. 

 Petals 5, with a broad gland at the base; style short, subulate, straight. 

 Acheues not seen. 



SOUTH Island: Otago : Rough and shingly places at the summit of the Rock and Pillar 

 Range, opposite Middlemaroh, and on the Old-Man Ringe. Petrie ! 4,000£t. and upwards. 



Closely related to R. Berggrenii, of which it may possibly prove to be a variety ; but this can 

 only be determined by the discovery of the ripe achenes of both species. 



19. R. recens, n. s. Stemless, depressed, less than lin. high. Leaves 

 rosulate, fin.— lin. long including the stout sheathing petiole, 3-foliolate, coria- 

 ceous ; leaflets deeply lobed or pinnatifid ; segments subacute or obtuse, glabrous 

 or with a few scattered hairs on the upper surface ; petiole strigose or glabrate. 

 Scapes about im. high, strigose, 1-flowered. Flowers not seen. Achenes 

 orbicular-ovate, slightly compressed, faintly keeled ; style minute, scarcely re- 

 curved. 



SOUTH Island : Otago : Alpine. Buchanan I Petrie ! 



The leaves approach B. Novae-Zelandiae, but the segments are smaller and more fleshy ; the 

 achenes are unlike those of any other species. I have only three small specimens. 



20. R. Enysii, T. Kirk in Trans. N.Z.I, xii. (1879) 394. Glabrous, 

 scapes erect, lOin.— 15in. high. Rootstock rather stout, with strong spreading 

 rootlets. Radical leaves on grooved petioles, 4in.— Bin. long; blade digitately 

 3— 5-foliolate or 2-ternate; leaflets petiolulate, obliquely-rounded, cuneate, shortly 

 lobed, with coarsely crenate or crenate- serrate margins, or 2-ternate or quinate, 

 the terminal segments irregularly lobed or cut. Scapes 2—5, exceeding the 

 leaves, simple or rarely with 1 or 2 branches, naked or with a single bract or 

 petioled leaf. Flowers fin. in diameter. Sepals broadly ovate, acute. Petals 

 5—10, broadly obovate, with a deep gland near the base. Achenes small, in 

 dense globose heads, glabrous, turgid, minutely reticulate ; style short, slender, 

 curved. — R. tenuis, Buch. in Trans. N.Z.I, xx. (1887) 255, t. 12. 



SOUTH Island : Canterbury : Mount Torlesse, Broken River, Coleridge Pass, &c., /. D. Enys ! 

 Otago : Mountains above Lake Harris, T. K. Bast Taieri hills, Buchanan, I.e. 2,000ft. to 3,500ft. 

 Dec, Jan. 



A very distinct species ; the margins of the leaves are often thickened and the teeth acute. 



21. R. verticillatus, n. s. Leaves all radical on slender petioles 3in. 

 long, broadly reniform, 3-lobate, margins lobed or crenate, glabrous. Scape 

 simple, with one or two whorls of linear bracts on the upper portion. Flowers 

 solitary. Sepals broadly ovate. Petals linear-oblong, fin. long. Achenes not 

 seen. Scape and bracts pubescent above. 



SOUTH Island : Canterbury : Near Lake Ohau, Buchanan ! 



I have only seen a very imperfect specimen of this plant, which appears distinct from all 

 other New Zealand species.
