Var. rufiglandulosus, Kirk, l.c.—Glandular-pubescent or glabrate. Leaves coarsely and sharply irregularly doubly dentate or serrate, sometimes lobed at the base. Corymbs very large. Achenes densely pubescent.—S. rufiglandulosus, Col. in Trans. N.Z. Inst. xxviii. (1896) 599.
Var. sinuatifolius, Kirk, l.c.—Stems slender, flexuose. Leaves distant, ovate-oblong, sinuate, not toothed. Corymbs small; heads few.
North Island: From the Paparata Valley and Waikato River southwards, but rare and local to the north of the East Cape. South Island: Western part of the Nelson Provincial District and Westland, not uncommon as far south as Ross. Sealevel to 3500 ft. November–February.
10. S. Banksii, Hook. f. Fl. Nov. Zel. i. 146.—An erect stout or slender perfectly glabrous branched herb 2–4 ft. high or more; stems flexuose, grooved. Leaves 2–5 in. long, 1–2 in. broad, broadly oblong or ovate-oblong to linear-oblong, acute or subacute, sessile with broad auricled amplexicaul bases, coriaceous or almost membranous, shining, often glaucous, coarsely and irregularly sinuate-serrate or dentate; veins reticulated, often prominent beneath; uppermost leaves smaller and narrower, lanceolate or linear. Corymbs broad, lax. Heads numerous, campanulate, ¼–⅓ in. broad; involucral bracts linear-oblong, acuminate, pubescent at the tips. Ray-florets 10–12; ligules short, revolute. Achenes linear, grooved, pubescent.—Handb. N.Z. Fl. 734; Kirk, Students' Fl. 342. S. odoratus, Hook. f. Handb. N.Z. Fl. 160 (not of Hornemann). S. pumiceus, Col. in Trans. N.Z. Inst. xxi. (1889) 89; Kirk, Students' Fl. 343.
Var. angustatus.—Much less robust and more rigid, glabrous or sparingly clothed with short scabrid hairs. Leaves 1½–3 in. long, ¼–¾ in. broad, lanceolate or oblong-lanceolate, acute, all sessile or the lower sometimes petiolate, coriaceous, sharply and irregularly sinuate-serrate; veins usually prominent beneath.—S. Banksii var. scabrosus, Hook. f. Fl. Nov. Zel. i. 147. S. pumiceus var. angustatus. Kirk, Students' Fl. 343.
North Island: Mokohinou Island, Herb. Col. Mus.! Mercury Bay, Banks and Solander; East Cape Island, Ross; Anaura and Tolago Bay, Banks and Solander, Adams and Petrie! near Table Cape, A. Hamilton! between Tolago Bay and Gisborne, Colenso. Var. angustatus: East Cape, A. Hamilton; Karangahake Cliffs, Lake Taupo, T.F.C. Sea-level to 1500 ft. December–January.
Mr. Kirk limits S. Banksii to a form with more decidedly fiexuous stems and rather membranous glaucous leaves, keeping up Colenso's S. pumiceus for the reception of those states with stouter and sfcraighter stems and more coriaceous leaves. But a series of the Tolago Bay plant, which is that collected by Banks and Solander, shows that this distinction cannot possibly be maintained, some of the specimens exactly matching the types of S. pumiceus in Mr. Colenso's herbarium, while others show a regular gradation to more slender and membranous forms. An examination of the ripe achenes of both varieties also proves that the supposed difference in size and shape does not exist.
11. S. Colensoi, Hook. f. Fl. Nov. Zel. i. 147.—An erect much or sparingly branched herb 10–20 in. high, more or less clothed with white cobwebby tomentum. Stems woody at the base,
