Carmichaelia (New Zealand broom, vh. unless stated otherwise)—There are about 21 species. All have green, leafless (or almost so) stems, except when young or in shade; frequently grow in dry ground and dry climate; many ascend to subalpine belt; fls. usually with white ground, striped, streaked or blotched purple. Cult., usually in almost any soil in sun; the dwarf species in sunny part of alpine garden or even in border. Prop., rooted pieces, young plants, seed. The following is a selection:—C. australis (makaka, h.) is 6 ft., or more; stems flat, varying in. width. C. compacta (vh.) is charming; 4 ft., most floriferous, sweet-scented. Hab., driest part of Central Otago. C. Enysii (vh.) forms dense, low mats of short, slender green stems; fls. abundant. C. uniflora, C. nana, and the taller, more robust C. Monroi (several vars.) are similar, but the last does not make carpets. Hab., for all four, stony ground, montane or subalpine, but the last two descend to the lowlands. C. grandiflora (vh.), of spreading habit, bears abundance of sweet-scented fls.; there are several varieties, one with white fls. Hab., stony ground, subalpine scrub, to 4,000 ft. C. angustata (vh.), often by sides of streams, is similar. C. odorata (vh.), the best for the open border, 10 ft., is erect and bushy. Hab., banks of streams, Ruahine Mountains to Marlborough Sounds. C. Williamsii (hh.), 8 ft., is remarkable for its very wide, flat stems; fls. large, pale-yellow, striped and blotched purple, Sp. Hab., East Cape district. Corallospartium crassicaule (coral-broom, vh.), allied to Carmichaelia, though not handsome, is striking for the alpine-garden in dry ground, with its peculiar very thick, yellowish, erect, leafless, grooved stems; fls., cream. Hab., dry, stony, ground in driest mountains of S. Island. C. racemosum (vh.) is more slender; grows in wetter climate. Chordospartium page 44Stevensonii (vh.) is a low, weeping, Carmichaelia-like tree with racemes of beautiful purple fls. Hab., eastern Marlborough. Cult., open border, dry ground. Notospartium Carmichaeliae (pink broom, vh.) and N. torulosum (vh.), come with the above; the first has pink fls. in abundance, and the latter purple; both become small trees. Hab., the first eastern Marlborough, bank of rivers, rock, and the second in similar positions south to Mt. Peel (Canterbury).
Cassinia (tauhinu, cottonwood vh. to hh.)—Erect, bushy shrubs; lvs. heath-like, small, entire, tomentose beneath; heads white, numerous, in corymbs. Cult., easy, even poor, dry soil in sun; bear trimming and need it when old. Prop., young plants, cuttings, seed. C. albida (vh.) and the more hoary var. canecens, both about 4 ft., are excellent. Hab., to 4,000 ft., Nelson and Marlborough. C. Vauvilliersii (vh.), of much wider distribution, is similar, but lvs. dark glossy-green, yellow-tomentose beneath. C. amoena (hh.), of the North Cape hill, 1 to 2 ft., is dense and floriferous, very pretty. C. leptophylla (tauhinu, h.), and C. retorta (hh.), 12 ft., are white-tomentose. C. fulvida (vh.) is similar, 5 ft., has branches and lvs. beneath yellow-tomentose; the var. montana is not so yellow. There are hybrids between C. leptophylla and C. fulvida.
Coprosma,—There are, at least, 40 woody species, varying from trees to mat-and cushion-plants; many are much-interlacing shrubs and others striking ever-greens or small trees; the dioec. fls. are insignificant, but the drupes are frequently abundant and beautiful. Hab., all kinds of stations and altitudes. Prop., young plants, seed (germinates well), and cuttings of large leaved vars. The following is a selection of the best:—C. acerosa (vh.), makes open, flattened, orange-page 45coloured wiry cushions, 2 ft.; drupes translucent stained blue. Hab., unstable dunes. C. rugosa (vh.), frequently subalpine, is similar, but much taller and erect. C. brunnea (vh.), is one of the élite of the flora, its stems hugging the ground but concealed by their strings of white, pale-blue, amethyst, or dark-blue, translucent, jewel-like drupes. Hab., stony river-bed in the montane and lower subalpine belt C. Baueri (taupata, hh.) is finally a beautiful small tree; lvs. wonderfully glossy, bright-green; drupes, orange. It bears trimming to any extent; makes splendid hedges; there are two variegated vars., the more deeply variegated is extremely beautiful trained to the wall of a house, etc., they may also sprawl over banks, etc. C. chathamica (h.) is similar to C. Baueri but not so good. C. grandifolia (kanono, hh.), 15 ft., has very large, broad lvs.; drupes, reddish-orange, showy. Hab., lowland forest to lat. 43° almost, C. lucida (karamu, vh.) is similar but lvs. smaller. Hab., forest to above 3,000 ft. C. robusta (vh.) is valuable for its rapid growth; lvs. still smaller. Hab. forest to 2,500 ft., swamp. Cult., rather rich soil for C. grandifolia, but any soil, or situation, for the two others. There are many hybrids between C. robusta and C. propinqua (not dealt with here), known as C. Cunninghamii, some with pretty yellow, white, or black drupes. C. linariifolia (yellow-wood, vh.) is 12 ft., or more; lvs. dark green, linear, 1 in. long; drupes black. Hab., forest to 3,000 ft. Cult., fairly good soil. C. Petriei (vh.) is a dense carpet-plant; drupes large, showy, sunk in the carpet, in one var. port-wine coloured and in the other var. pale translucent blue. Hab., stony tussock-grassland. Cult., alpine-garden, in slight shade. C. ramulosa (vh.) forms broad, twiggy mats; drupes red, translucent, abundant, showy. Cult., alpine-garden, partial shade.page 46

Traversii (see fig. 9) worth every effort to establish in the alpine-garden. Cult., not particularly difficult in wet localities, but requires drainage and shade in dry districts. Prop., well-rooted young plants, or a fair-sized, rooted piece of an old plant may be tried, seed (very slow). D. recurvum (vh.) forms reddish, open, twiggy cushions, Volcanic Plateau, to 5,000 ft., in pumice; is difficult but striking when established. Cult., alpine-garden in more or less shade.

Kirkii and D. subulatum.
Elytranthe (mistletoe, vh.) contains E. Colensoi and E. tetrapetala (vh.), shrubby parasites with green lvs. and gorgeous scarlet fls. Both may be established by inserting the sticky berries on small branches, or twigs, of Nothofagus Menziesii (for the first) and N. cliffortioides (for the second); probably there will be many failures. In nature the berries are attached to their host by the middle of April.

Olearia (tree-daisy)—New Zealand possesses at least 40 species (and a number of hybrids) which for beauty of form and profusion of blossoms are unsurpassed, while their value for garden decoration equals that of the veronicas. Following, the species are arranged in three classes including O. insignis.
Group 1.—Most are mountain species usually of subalpine scrub or the uppermost belt of low forest, vh.; flower-heads small, numerous, white, generally in large panicles; lvs. stiff, thick, tomentose beneath. Cult., almost any well-drained soil, tolerate wind and full sun, bear trimming well, apt to become "leggy" with age. Prop., cuttings (strike readily) autumn or early page 52spring, may bloom the succeeding season, young plants, seed (often not fertile).
O. arborescens (nitida) is most charming; lvs. broadly ovate, 1½ to 2½ in. long, white beneath with satiny tomentum, more or less toothed; fls. in the greatest profusion, Sp.; the var. angustifolia has thin lanceolate lvs. O. capillaris has small lvs., ¼ in. long; there are hybrids between this and O. arborescens worth cultivating. O. avicenniaefolia is eventually a low tree; lvs. broadly lanceolate, greyish, white-tomentose beneath. O. furfuracea (akepiro, h.) has lvs. broadly oblong or broadly ovate, 2 to 4 in. long, shining silvery beneath, margin often wavy. The related O. Allomii (hh.) is only 1 to 3 ft. high. Hab., Great Barrier Island. O. pachyphylla (hh.) is smaller than O. furfuracea and its flower-heads furnished with numerous involucral scales, are quite ¾ in. long. Hab., Bay of Plenty. O. Haastii (vh.) is rare as a wild plant, yet the commonest in the gardens of Great Britain; lvs. about 1 in. long, more or less oblong, white tomentose beneath. O. oleifolia (vh.) has longer lvs.; it and O. avicenniaefolia probably cross. O. nummularifolia has smaller lvs. than O. Hastii, more or less orbicular; flower-heads solitary. O. cymbifolia (vh.) is the last-named with the lvs. bent back so as to be boat-shaped; there are many wild hybrids between the two. O. moschata (vh.) is distinct with its small whitish obovate lvs., white-tomentose beneath. There is a beautiful hybrid between this and O. ilicifolia in the Queenstown Gardens (see fig. 1), most likely a wild plant. O. Forsteri (akiraho, vh.) has only one floret to each flower-head, and belongs to the sub-genus Shawia. It frequently grows on rocks; lvs. oblong to broadly ovate, 1½ in. to 3 in. long, waved on margin; fls. fragrant, A.; there is a large-leaved variety page 53O. coriacea has smilar flower-heads, but hard, small, saddle-shaped lvs. Hab., dry rocks, E. Marlborough. O. ilicifolia (mountain-holly, vh.) has linear-oblong or lanceolate lvs., 2 to 4 in. long, greyish above, yellowish-white beneath, musk-scented, margin strongly waved and spinous-toothed. O. macrodonta, closely allied, has greener, broader, toothed (not spinous) lvs. O. lacunosa (vh.) (see fig. 20), is most striking with its dark-green, long, narrow, glossy lvs., 7 in. long by ¼ to 1 in. broad, with a prominent midrib beneath from which pass off stout veins making sunken interspaces covered with rust-coloured tomentum; there are wild hybrids, excellent for gardens, between this and O. arborescens. O. mollis is probably O. lacunosa x ilicifolia, but more nearly resembles the latter. The delightful O. suavis is possibly another "lacunosa" hybrid. O. excorticata (vh.) is much like O. lacunosa but has broader lvs.
Geoup 2.—Coastal species (except O. Colensoi) of great beauty of form, with sometimes long-stalked brilliantly-coloured flower-heads, suggesting glorified michaelmas daisies; lvs. thick, toothed, usually lanceolate, white-tomentose beneath. Cult., fairly easy, south and west of S. Island, difficult and disappointing in dry or hot localities, and in the N. Island generally; moist, deep, well-drained soil; frequent rain, or watering necessary. Prop., young plants, cuttings, seed.
O. angustifolia (tete-a-weka, h.) is eventually a small, dense, round-headed tree; power-heads 2 in. diam., centre purple, rays white, S. Hab., extreme south of South Island, common Stewart Island exposed to sea-spray. O. Traillii (h.) is a cross between this and O. Colensoi, heads in racemes. O. semidentata, (h.), one of the élite of the New Zealand flora, growing in bogs, Chathams, is most page 54lovely with its brilliant purple fls. O. chathamica (h.) is taller, its heads purple in centre, but rays usually white. O. Colensoi (vh.), N. and S. Islands, ascends to 5,000 ft., has broad, toothed lvs., 2 to 4 in. long; fls. poor, in racemes. The Stewart Island coastal form has much larger lvs. and may really be the next species. O. Lyallii (vh.) is a small tree; lvs. very broad, up to 8 in. long, white-tomentose beneath. Hab., Lord Auckland and Snares Islands.
Group 3.—Various lowland, or montane, species of forest, swamp, or sea-coast.

O. lineata (vh.) is an extremely graceful tree with slender, drooping branchlets; lvs. extremely narrow, 1 in. long; fls. fragrant, S. Hab., shrubland, dry parts of S. Island, to upper montane belt. O. fragrantissima (h.) is a small tree with thin, elliptic-lanceolate lvs., silky tomentose beneath; heads crowded; fls. fragrant, S. Hab., open forest, rare, Canterbury, Otago. Cult., good soil, sun. O. Hectori (vh.) is similar, but heads are stalked. O. Traversii (Chatham akeake, vh.) is a most important small tree, growing naturally on dunes, and rocks, and in forest, and swamp; it is valuable for hedges, dunereclamation, seaside planting, shelter and ornament; lvs. oblong to broad-ovate, 1 to 2 in. long, silky beneath.
