not auricled nor truncate, margins scarious, ciliate with copious white hairs; blade 125–112 in. wide at the base, gradually tapering upwards, rigid and coriaceous, upper surface more or less silky-pubescent, concave or nearly flat, lower glabrous, convex or almost keeled towards the tip, margins ciliate with white hairs for their whole length. Flowers white, about ¼ in. long, in dense 3–6-flowered spike-like racemes ½–¾ in. long. Bracts broadly ovate, acuminate, silky within, margins ciliate. Sepals ovate, acuminate, ciliate, about equalling the corolla-tube. Corolla-lobes short, triangular, acute. Capsule broadly obovate, included within the persistent calyx-lobes.—Fl. Nov. Zel. i. 170. D. Urvilleanum var. scoparium, Handb. N.Z. Fl. 182 (in part).
Var. major.—Taller and stouter, often 20–30 ft. high when fully adult. Leaves of mature plants 1½–3 in., margins more copiously ciliate; of young plants or of the lower branches of old ones 6–9 in. long or more, ⅓–¾ in. wide, flat, ciliate, gradually tapering into long acuminate points. Racemes 4–8-flowered; flowers rather larger. Bracts and calyx-lobes often silky on the back.-D. latifolium var. ciliolatum. Hook. f. Handb. N.Z. Fl. 736 (young plant). D. arboreum, Cockayne in Trans. N.Z. Inst. xxxiv. (1902) 318.
Var. paludosum. Smaller, 3–6 ft. high when adult, and often flowering when less than 6 in. Leaves 1–1½ in., not longer and wider in the young state. Racemes short, 2–4-flowered; flowers rather smaller.—D. rosmarinifolium, Buch. in Trans. N.Z. Inst. vii. (1875) 338 (not of Worst.). D. paludosum, Cockayne in Trans. N.Z. Inst. xxxiv. (1902) 318.
Campbell Island: Near the sea, not common, Hooker, Kirk! Chatham Islands: Var. major and paludosum not uncommon, the latter chiefly in swamps, Dieffenbach, H. H. Travers! Enys! Cox and Cockayne!
Closely allied to D. Urvilleanum, to which it was reduced by Sir J. D. Hooker in the Handbook, but constantly differing in the conspicuously ciliate margins of the leaves, which are also silky-pubescent on the upper surface. The leaf-sheaths are also never auricled or truncate, as in D. Urvilleanum, but are simply rounded at the top, passing more gradually into the blade. My two varieties major and paludosum are both treated as distinct species by Mr. Cockayne. It is possible that he may be correct with respect to var. major, which differs not only in its much larger size, but also in the very distinct leaves of the juvenile stage. But the leaves and flowers of the mature stage are in both varieties so very similar to those of the original Campbell Island plant that I hesitate to separate either of them.
12. D. subulatum, Hook. f. Fl. Antarct. i. 50.—An erect shrub 2–6 ft. high, with long slender twiggy branches leafy at the tips; bark dark red-brown or almost black. Leaves small, strict or liexuose, ⅓–1 in. long, rarely more; sheathing base 112–110 in. broad, truncate or auricled at the tip; blade very narrow, 130–140 in. wide at the base, pungent, rigid and coriaceous, concave or flat above, convex beneath, triquetrous at the tip, glabrous on the margins, most minutely serrulate. Leaves of young plants larger, sometimes ¾–1½ in. long by 112 in. wide at the base, spreading or recurved. Racemes small, lateral, often crowded along the branches, 2–6-flowered. Flowers small, 110–18 in. long. Bracts with broadly
