Manual of the New Zealand Flora.

21. Senecio, Linn

21. Senecio, Linn.

Herbs, shrubs, or small trees of exceedingly various habit, glabrous or pubescent or more or less woolly or tomentose. Leaves alternate, entire or variously divided. Heads solitary or corymbose or paniculate, heterogamous and radiate or homogamous and discoid. Involucre from cylindrical to hemispherical; bracts in 1 or 2 series, nearly equal, erect, free or connate below, usually with a few much shorter ones at the base. Receptacle flat or convex, naked, pitted or fimbrillate. Florets of the circumference female, ligulate, sometimes sterile or wanting. Disc-florets hermaphrodite, tubular, 5-toothed. Anthers obtuse at the base or minutely tailed. Style-branches of the hermaphrodite florets recurved, their tips truncate or penicillate. Achenes subterete, usually ribbed or striate. Pappus-hairs copious, soft, white, smooth or scabrid or barbellate.

The largest genus of Compositæ, if not of flowering plants generally, probably containing fully 1,000 species. It is found in all parts of the world, stretching from the equator to the limits of phæsenogamic vegetation in both the arctic and antarctic regions, but is most abundant in temperate and mountainous districts. Few of the species have wide ranges, and many have a very restricted distribution. Of the 30 found in New Zealand, one extends to Australia, the rest are all endemic. The herbaceous species are exceedingly variable, and some of them difficult to determine; but the shrubby varieties are remarkably distinct. Some of them, such as S. Hectori and S. Kirkii, must be ranked amongst the most beautiful members of the flora.

S. Pottsii, Arinstr. in Trans. N.Z. Inst. iv. (1872) 290, is quite unknown to me, and there are no specimens in any colonial herbaria. It is described as a small slender suffruticose species with decumbent flexuose branches 3–6 in. long, the branches, petioles, and leaves beneath clothed with loose white cottony tomentum. Leaves petiolate,½–1 in. long, ovate or spathulate, glabrous above, crenate.

S. dimorphocarpos, Col. in Trans. N.Z. Inst. xxvi. (1894) 316, is S. jacobœa, Linn., the common ragwort of the Northern, Hemisphere, which has become naturalised in many districts in both the North and South Islands. It is a tall almost glabrous perennial 2–4 ft. high, with irregularly pinnatifid or 2-pinnatifid leaves 2–6 in. long, a dense corymb of rather large heads ⅔–1 in. diam., bright-yellow rays, and glabrous ribbed achenes.

S. areolatus, Col. l.c. 317, is S. sylvaticus, Linn., another common northern plant which has become established in New Zealand. An annual slightly glandular-pubescent herb 1–3 ft. high, with irregularly pinnatifid leaves 1–3 in. long, loose corymbs of small heads ⅓ in. diam., with very short revolute rays and silky ribbed achenes.

Several other species of Senecio have become naturalised, the most widely distributed being S. vulgaris, Linn., the common groundsel, which can be recognised by its small size, 6–12 in. high, succulent grooved stems often branched from the base, irregularly pinnatifid or toothed leaves, small cylindric heads with the florets all tubular and hermaphrodite, and an involucre of about 20 equal bracts.

1.S. lagopus, Raoul in Ann. Sci. Nat. Ser. iii. 2 (1844) 119, t. 18.—Rootstock stout, densely clothed at the top with long brownish silky wool.

South Island, Stewart Island: Not uncommon in mountain districts throughout. 2000–5000 ft. December–February.

This appears to pass into &. S. lagopus, but in its usual state can generally be distinguished by the smaller size and more membranous leaves, which are often quite glabrous beneath, seldom white and cottony.

South Island: Port Lyttelton and other localities on Banks Peninsula, not uncommon. January–March.

A handsome species, separated from large states of S. lagopus, some of which approach it. very closely, by the much stouter habit, more copious villous hairs, and larger thicker leaves, which are silky above and never show the stout bristly hairs so characteristic of S. lagopus and bellidioides.

5.S. Lyallii, Hook. f. Fl. Nov. Zel. i. 146.—A leafy herb 1–2 ft. high or more, usually glandular-pubescent or almost villous, rarely glabrate. Rootstoek thick, crowned with long silky hairs.

An exceedingly handsome plant, forming one of the chief ornaments of the subalpine flora of the South Island.

6.S. antipodus, T. Kirk, Students' Fl. 341.—An erect much- branched annual or biennial herb 1–2 ft. high; stems stout, fistulose, ⅓–½in. diam.; branches spreading, grooved. Leaves page 373membranous, rather succulent, 2–5 in. long, lower narrowed into a petiole, upper sessile with broad amplexieaul auricles, deeply and irregularly pinnatifid; segments few, 1–2 in. long, acute, toothed or lobed or almost pinnatifid, glabrous above, mealy-tomentose beneath.

Kermadec Islands, North and South Islands, Stewart Island, Chatham Island: Abundant near the sea, not so common inland. Sea-level to 4500 ft. October–March.

This is a widely diffused plant in Australia and Tasmania as well as New Zealand, and is everywhere exceedingly variable, not a few forms having been described as distinct species. The chief varieties found in New Zealand may be briefly characterized as follows, but it must be borne in mind that intermediates are not uncommon:—

Var. a.—Much branched, erect or decumbent. Leaves deeply pinnatifid; segments long and narrow, often again toothed, rarely short and broad. Heads ⅓–½ in. diam., radiate.—Usually near the coast, but occasionally found inland. Mr. Kirk's variety carnosulus is probably a form of this.

Var. montanus.—Sparingly branched or quite simple, erect. Leaves oblong to lanceolate or spathulate, entire or toothed or shortly pinnatifid. Heads ½–¾ in. diam., radiate; rays often revolute.—A common mountain plant in both the North and South Islands.

page 374

Var. discoideus.—Sparingly branched, prostrate or decumbent, rarely erect. Leaves very fleshy, obovate or spathulate, coarsely toothed or lobed, sometimes pinnatifid below. Heads large, ½–¾ in. diam.; rays wanting.—Mountain districts in the South Island.

Var. radiolatus, Kirk, Students' Fl. 341.—More or less pubescent. Lower leaves broad, membranous, narrowed into slender petioles, toothed or lobed or pinnatifid; upper sessile, auricled at the base. Heads ⅓–½ in., radiate; rays short, broad. Achenes very mucilaginous when soaked in warm water.—S. radiolatus, F. Muell. Veg. Chath. Is. 24, t. 4. Chatham Islands, H. H. Travers! Cox and Cockayne!

8.S. glaucophyllus, Cheesem. in Trans. N.Z. Inst. xxviii. (1896) 536.—Smooth and glaucous, perfectly glabrous, 1–3 ft. high. Rootstock stout, woody. Stems numerous, strongly grooved, simple or sparingly branched, naked at the base or with minute scale-like leaves only, leafy above. Leaves 2–4 in. long, ½–1 in. wide, oblanceolate or oblong-obovate or obovate-spathulate, obtuse or subacute, gradually narrowed into broad flat petioles, not dilated nor sheathing at the base, irregularly sinuate-dentate or serrate, rather thin, very glaucous; margins somewhat thickened. Upper leaves narrower, lanceolate or linear-lanceolate, serrate, gradually passing into narrow-linear entire bracts. Heads several in a loose terminal corymb, broadly campanulate, ⅓ in. diam.; involucral bracts linear, acuminate, 2-ribbed, glabrous or pilose at the tips. Ray-florets about 15; disc-florets numerous, Achenes not seen.—Kirk, Students' Fl. 343.

South Island: Nelson—Mount Arthur, on limestone rocks, alt. 4000 ft., T. F. C. January.

A very curious plant, its bushy mode of growth and glaucous leaves giving it a very different appearance to any of its allies. The stems appear to die down to the root in winter, a fresh crop appearing in the following spring. My specimens are in young flower only, and the above description may require modification when more perfect, examples have been obtained.

9.S. latifolius, Banks and Sol. ex Hook. f. Fl. Nov. Zel. i. 145.'—A tall erect much-branched glabrous herb 2–4 ft. high; stems flexuous, grooved.

Corymbs broad, lax, much branched; branches slender. Heads very numerous, ½–¾ in. diam.; involucral bracts in 1 series, linear, acuminate, glabrous or pubescent. Ray-florets 12–20; ligule narrow, spreading. Disc-florets 30–40. Achenes linear, grooved, hispidulous. Pappus-hairs soft, copious, white.—Hook.f. Handb. N.Z. Fl. 159; Kirk, Students' Fl. 341. page 375

10.10. S. Banksii, Hook. f. Fl. Nov. Zel. i. 146.—An erect stout or slender perfectly glabrous branched herb 2–4 ft. high or more; stems flexuose, grooved. Leaves 2–5 in. long, 1–2 in. broad, broadly oblong or ovate-oblong to linear-oblong, acute or subacute, sessile with broad auricled amplexicaul bases, coriaceous or almost membranous, shining, often glaucous, coarsely and irregularly sinuate-serrate or dentate; veins reticulated, often prominent beneath; uppermost leaves smaller and narrower, lanceolate or linear. Corymbs broad, lax. Heads numerous, campanulate, ¼–⅓ in. broad; involucral bracts linear-oblong, acuminate, pubescent at the tips. Ray-florets 10–12; ligules short, revolute. Achenes linear, grooved, pubescent.—Handb. N.Z. Fl. 734; Kirk, Students' Fl. 342. S. odoratus, Hook. f. Handb. N.Z. Fl. 160 (not of Horne- mann). S. pumiceus, Col. in Trans. N.Z. Inst. xxi. (1889) 89; Kirk, Students' Fl. 343.

Var. angustatus.—Much less robust and more rigid, glabrous or sparingly clothed with short scabrid hairs. Leaves 1½–3 in. long, ¼–¾ in. broad, lanceolate or oblong-lanceolate, acute, all sessile or the lower sometimes petiolate, coriaceous, sharply and irregularly sinuate - serrate; veins usually prominent beneath.—S. Banksii var. scabrosus, Hook. f. Fl. Nov. Zel. i. 147. S. pumiceus var. angustatus, Kirk, Students' Fl. 343.

North Island: Mokohinou Island, Herb. Col. Mus.! Mercury Bay, Banks and Solander; East Cape Island, Boss; Anaura and Tolago Bay, Banks and Solander, Adams and Petrie! near Table Cape, A. Hamilton! between Tolago Bay and Gisborne, Colenso. Var. angustatus: East Cape, A. Hamilton; Karangahake Cliffs, Lake Taupo, T. F. C. Sea-level to 1500 ft. December–January.

Mr. Kirk limits S. Banksii to a form with more decidedly flexuous stems and rather membranous glaucous leaves, keeping up Colenso's S. pumiceus for the reception of those states with stouter and straighter stems and more coriaceous leaves. But a series of the Tolago Bay plant, which is that collected by Banks and Solander, shows that this distinction cannot possibly be maintained, some of the specimens exactly matching the types of S. "pumiceus in Mr. Colenso's herbarium, while others show a regular gradation to more slender and membranous forms. An examination of the ripe achenes of both varieties also proves that the supposed difference in size and shape does not exist.

11.S. Colensoi, Hook. f. Fl. Nov. Zel. i. 147.—An erect much or sparingly branched herb 10–20 in. high, more or less clothed with white cobwebby tomentum. Stems woody at the base, page 376 flexuose, grooved. Leaves very variable, 1–4 in. long,½–1½ in. broad, broadly oblong or obovate to lanceolate, obtuse or acute, sessile with broad amplexicaul bases or petiolate with auricles at the base of the petioles, coriaceous; margins sinuate-dentate or serrate or deeply irregularly lobulate or pinnatifid, hoary or cobwebby on both surfaces or on the lower surface only. Corymbs terminal, usually lax. Heads few or many, ⅓–½in. diam., cam-panulate; involucral bracts linear-oblong, acute or acuminate. Rays short, revolute.

Nobth Island: Common in hilly and wooded districts from the North Cape to Wellington. Sea-level to 2500 ft.

A very remarkable and beautiful species. The flower-heads are often so abundantly produced as to conceal the leaves, the multitude of snow-white rays then rendering the plant conspicuous from afar. In the northern forests it is often epiphytic on the distorted trunks of the rata (Metrosideros robusta).

This is clearly identical with Armstrong's S. Stewartiœ, a name which has two years' priority over the S. Muelleri of Kirk. It is very closely allied to the preceding species, but the leaves are more acuminate, and the tomentum of [unclear: the] under-surface is whiter, while the narrow contorted rays are quite unlike the short broad ones of S. Huntii.

19.S. laxifolius, Buch, in Trans. N.Z. Inst. ii. (1870) 89.—A small diffusely branched shrub 1–4 ft. high; branchlets, leaves beneath, and inflorescence densely clothed with white cottony tomentum.

Mr. Kirk has described the South Island plant as a distinct species under the name of S. viridis. It is somewhat larger in all its parts, but differs in no essential character, and is far better regarded as a variety only. Specimens of S. Bidwillii collected at the foot of Ruapehu by the Rev. F. H. Spencer almost match others gathered in the South Island by myself.

South Island: Mountains of Nelson, Marlborough, and Canterbury; not uncommon from Mount Arthur to the Upper Waimakariri. 1500–4500 ft. January–February.

A very remarkable species, with a more rigid pappus than is usual in Senecio, and in other respects resembling the Juan Fernandez genera Balbisia and Robinsonia. Sir J. D. Hooker created the genus Traversia for its reception, but in the "Genera Plantarum" it was reduced to Senecio.
