21. C. Buchanani, T. Kirk in Trans. N.Z. Inst. xxiv. (1892) 424.—A much and closely branched shrub 5–10 ft. high; branches numerous, ascending, younger ones finely pubescent; bark reddish-brown. Leaves distant, ½–1 in. long, broadly oblong or obovate, obtuse or minutely apiculate, narrowed into a short pubescent petiole, rather coriaceous, puberulous and minutely ciliate when young, margins thickened. Stipules deltoid, acute, minutely ciliate. Male flowers unknown. Females axillary, solitary or in 2–3-flowered fascicles, involucellate. Calyx-limb minutely 4–5-toothed. Corolla narrow-campanulate, 4–5-lobed to the middle; segments acute, recurved. Styles stout. Fruit unknown.—Students' Fl. 239.
North Island: Wellington—Near Cape Terawhiti, Buchanan, Kirk! October.
Apparently a very distinct species, the true affinities of which cannot be determined until the male flowers and fruit have been observed.
22. C. crassifolia, Col. Excurs. North Is. 75.—A much-branched rigid shrub 4–12 ft. high; branches divaricating, excessively stiff and rigid, often interlaced; branchlets glabrous or minutely puberulous; bark reddish-brown or greyish-brown, uneven and fissured on the branches, smoother on the twigs. Leaves ¼–¾ in. long, rarely more, broadly oblong or obovate to orbicular, rounded at the tip or retuse, abruptly narrowed into a very short petiole, usually thick and coriaceous, often glaucous beneath; margins thickened; veins obscure. Flowers involucellate, solitary or more rarely in 2–3-flowered fascicles. Male flowers: Calyx wanting. Corolla 15 in. long, campanulate, 4-partite almost to the base. Stamens 4. Female flowers: Calyx-limb minute, truncate or obsoletely toothed. Corolla tubular, 18–17 in. long, deeply 4-lobed. Drupe ¼ in. long, subglobose or broadly oblong, yellow, sometimes white and translucent.—Cheesem. in Trans. N.Z. Inst. xix. (1887) 242; Kirk, Students' Fl. 238. C. pendula, Col. in Trans. N.Z. Inst. xxi. (1889) 84.
North and South Islands: From Hokianga southwards to Otago, but often local. Sea-level to 1200 ft. September–November.
Best distinguished by the excessively stiff and rigid habit, almost glabrous branchlets, rounded coriaceous leaves, and subglobose yellow fruit. Mr. Colenso's C. pendula has much thinner leaves, but is not otherwise different.
23. C. rigida, Cheesem. in Trans. N.Z. Inst. xix. (1887) 243.—An erect shrub 5–15 ft. high; branches divaricating, stout or slender, open or much interlaced, glabrous or the very young twigs puberulous; bark reddish- or purplish-brown. Leaves in opposite pairs on short lateral branchlets, ¼–¾ in. long, obovate or oblongspathulate, rounded or retuse, gradually narrowed into a short petiole, coriaceous or almost membranous, quite glabrous; veins
