310 Of this I have only seen a single leaf from Mr. Chapman's type, and a specimen of what appears to be the same collected by Mr. Petrie in the Clinton Valley. Further material is required to prepare a satisfactory description. It appears to differ from C. verbascifolia in the smaller size, thinner and more appressed tomentum, and much less woolly scapes, bracts, and involucres. A plant gathered by Mr. Cockayne on the Humboldt Mountains seems to be intermediate between the two species.

Zel.'' 19, t. 14.—Leaves 6–20 in. long, 2–4 in. broad, linear-lanceolate, acuminate, gradually narrowed to the base, quite entire, membranous, glabrous on both surfaces when mature or slightly cottony at the base, often rather glaucous beneath; petiole broad, grooved, sheathing at the base, usually cottony on the inner surface. Scapes 12–24 in. high, stout, glabrous or sparingly cottony; bracts numerous, lanceolate, acuminate, sheathing at the base. Heads about 2 in. diam.; involucral bracts numerous, ovate-lanceolate, acuminate, membranous, glabrous. Rays long and narrow. Disc-florets very numerous; corolla thickened at the base. Achene linear, glabrous, strongly ribbed.—''Hook. f. Fl. Nov. Zel. i. 122; Handb. N.Z. Fl. 133; Kirk, Students' Fl.'' 287. C. coriacea, ''Raoul, Ann. Sci. Nat. 1844, 119 (non Hook. f.'').

25. C. coriacea, Hook. f. Fl. Antarct. i. 36.—Leaves 8–24 in. long or more, ¾–3 in. broad, lanceolate or linear-lanceolate or linear-oblong, acute, narrowed towards the base, coriaceous, upper surface longitudinally furrowed or almost plicate and covered with a delicate silvery pellicle, beneath clothed with appressed white and silvery tomentum; margins entire or very obscurely serrulate; sheaths short, broad, grooved, densely clothed with soft cottony or woolly tomentum. Scapes stout, 1–3 ft. high, densely woolly or cottony; bracts numerous, linear, erect, cottony. Head 1½–3 in. diara. or more; involucral bracts numerous, linear-subulate, cottony or almost glabrate. Rays very numerous, spreading, 1½ in. long; tube of corolla more or less pubescent. Achene linear, compressed, grooved, pubescent.—Fl. Nov. Zel. i. 121, t. 32; ''Handb. N.Z. Fl. 132; Kirk, Students' Fl.'' 287. C. Martini, ''Buch, in Trans. N.Z. Inst.'' xix. (1887) 213. C. flaccida, ''Cockayne in Trans. N.Z. Inst.'' xxxi. (1899) 422. Aster coriaceus, ''Forst. Prodr. n. 297; A. Rich. Fl. Nouv. Zel. 250; A. Cunn. Precur.'' n. 439.
