rather longer than the sepals in the only perfect flower I have seen; gland a little below the middle. Achenes forming a rather large rounded head, compressed, margined, with a stout slightly hooked style.—Handb. N.Z. Fl. 7; Kirk, Students' Fl. 15.
Campbell Island: Apparently rare. Dr. Lyall (Antarctic Expedition), Lieut. Rathouis! Dr. Filhol! Kirk!
A specimen in my possession collected by Dr. Filhol, of the French Transit of Venus Expedition, almost exaccly matches a drawing taken from the type specimen at Kew. Mr. Kirk's specimens are much taller and more slender, with long petioles and a flowering-stem much exceeding the leaves, but evidently belong to the same species. It is probably a variable plant, and better specimens are required to furnish a good description. Its nearest ally is R. hirtus, from which it differs in the short rigid pubescence, in the leaves, in the sepals not being reflexed, and in the larger heads of achenes, which are more turgid and have much stouter beaks.
26. R. Hectori, T. Kirk, Students' Fl. 16.—Erect, 6–15 in. high, whole plant more or less clothed with strigose or appressed hairs. Rootstock short. Leaves chiefly radical, reticulate above when fresh, fleshy, hairy on both surfaces; petioles 4–7 in. long, slightly sheathing at the base; blade 1–11⁄2 in. long and broad, ovate-orbicular, 3-lobed to below the middle, truncate or slightly cordate at the base, lobes acute or subacute. Scapes 1–2; peduncles 2 or 3. Cauline leaves petiolate, 3-partite, the segments sparingly lobed or toothed. Receptacle ovate or conical, papillose, sparingly hairy. Flowers not seen. Achenes glabrous, narrowed below, oblique, slightly turgid, faintly keeled or margined; style shortly subulate, slightly recurved.
Auckland Islands: Sir James Hector!
This is based on a single very imperfect specimen in Mr. Kirk's herbarium, and in the absence of additional information I have reproduced his description. It is probably a mere state of R. aucklandicus with longer petioles and a branched scape.
27. R. aucklandicus, A. Gray, Bot. U.S. Expl. Exped. i. 8.—Rather stout, 6–12 in. high, strigose-hirsute in all its parts. Rootstock short, stout. Radical leaves on petioles 3–6 in. long, sheathing at the base; blade 1–11⁄2 in. diam., rounded-reniform in outline, silky-strigose on both surfaces, 3-cleft to or beyond the middle, with the sinuses usually closed; lobes broadly cuneate, again 2-3-lobed or coarsely cut and incised. Scapes 1–3, rather stout, 6–10 in. high, 1-flowered, usually with 1–2 cauline leaves towards the base. Flowers not seen. Fruiting-receptacle 1⁄4 in. long, cylindric or club-shaped, papillose, hairy. Achenes ovate, compressed, not margined; style subulate, short, straight.—Hook. f. Handh. N.Z. Fl. 723; Kirk, Students' Fl. 16.
Auckland Islands: U.S. Exploring Expedition, Kirk!
In habit approaching very near to some forms of R. lappaceus, but its nearest ally is undoubtedly R. subscaposus. I suspect that it and the two preceding are varieties of one species, but to prove this much more complete material will be required.
