23. S. revolutus, T. Kirk, Students' Fl. 348.—A small robust shrub 6–20 in. high; branches stout, often decumbent at the base, suberect above. Leaves viscid, on petioles ⅓–¾ in. long; blade 1–2½ in., oblong-lanceolate or elliptic-lanceolate to elliptic-oblong, obtuse, narrowed into the petiole, qaite entire, coriaceous, glabrous and reticulated above, beneath clothed with pale-buff or white appressed viscid tomentum. Corymb terminal, dense, about 2 in. diam., on a long and stout peduncle clothed with ascending linearoblong foliaceous bracts; peduncle and pedicels tomentose. Heads 5–15, campanulate, ½–¾ in. diam.; involucral bracts linear, acute, tomentose and viscid. Ray-florets 10–15, yellow; ligules broad, revolute. Disc-florets numerous; limb campanulate, 5-toothed. Achenes linear-oblong, grooved, glabrous.—S. robustus, Buch. in Trans. N.Z. Inst. vi. (1874) 243 (not of Sch. Bipont.).

South Island: Otago—Ben Lomond, Mount Bonpland, and other high peaks to the west, Petrie! mountains above Lake Harris, Kirk! Mount Eglinton, Morton! 3000–4500 ft. January–March.


24. S. Adamsii, Cheesem. in Trans. N.Z. Inst. xxviii. (1896) 536.—A small robust much-branched shrub 3–5 ft. high; young branches, leaves, and inflorescence excessively viscid. Leaves shortly petiolate, 1–2 in. long, oblong or oblong-obovate, obtuse, quite entire, extremely thick and coriaceous, glabrous above, beneath covered, except the midrib, with dense white or pale-buff closely appressed tomentum; margins revolute. Corymbs terminal, few-flowered, laxly branched; peduncles and pedicels nearly glabrous but excessively viscid; bracts varying from oblong to linearspathulate. Heads 5–15, broadly campanulate, ¾ in. diam.; involucral bracts linear, obtuse, almost glabrous except a tuft of woolly hairs at the tip. Ray-florets 10–15, yellow; ligules ¼ in. long, spreading. Disc-florets numerous; limb 5-toothed. Achenes glabrous or pubescent. Pappus-hairs white, slender, scabrid.—Kirk, Students' Fl. 348. S. pachyphyllus, Cheesem. in Trans. N.Z. Inst. xvi. (1884) 410 (not of Remy ex G. Gay).

North Island: Mount Holdsworth, Tararua Range, W. Townson! South Island: Nelson—Mount Arthur and Mount Peel, T.F.C.; Mount Rintoul and Ben Nevis, Gibbs, Bryant; Mount Duppa, J. Macmahon! 3500–5500 ft. January–February.

Distinguished from S. revolutus by the much more coriaceous leaves, with the midrib prominent beneath, narrow laxly branched corymbs, and by the peduncles, pedicels, and involucral bracts being nearly glabrous.


25. S. bifistulosus, Hook. f. Fl. Nov. Zel. i. 144.—A small much-branched shrub 1–2 ft. high; branches decumbent at the base, erect above; bark pale, closely marked with the scars of the fallen leaves. Leaves crowded at the tips of the branches, spreading, 1 in. long, 1/12 in. broad, narrow-linear, subacute, coriaceous, grooved above, beneath with the margins revolute to the midrib, a
