Names
Senecio deltoideus Less. [family COMPOSITAE], SYN. Comp.: 392 (1832); Oliv. & Hiern, F.T.A. 3: 420 (1877); Hilliard, Comp. Natal: 492 (1977); C.

Cap., pre-1837, which is possibly this specimen - there are no other Sonnerat sheets of this taxon) Eupatorium auriculatum Lam. [family COMPOSITAE], Encycl. 2: 410 (1788), non Senecio auriculatus N.L.Burm. (1768). Type as for S. deltoideus Senecio sarmentosus O.Hoffm. [family COMPOSITAE], in E.J. 20: 236 (1894), nom. illegit., non (Bl.) Schweinf. (1867); T.T.C.L.: 159 (1949). Type: Tanzania, Lushoto District: Usambara Mts, Holst 439, 621 (B†, SYN.), 3256a (B†, M!, SYN.) & 8914 (B†, K!, SYN.) Senecio rooseveltianus De Wild. [family COMPOSITAE], Pl. Bequaert. 5: 129 (1929). Type: Kenya, Nairobi, Mearns 984 (BR!, holo., BM!, iso.) Senecio tanzaniensis Cuf. [family COMPOSITAE], E.P.A.: 1159 (1967). Type as for S. sarmentosus O. Hoffm.
Information
Scandent perennial herb or liana; stems 2–7 m long, green, ribbed, finely pubescent, often glabrescent. Leaves ovate-triangular or triangular, 4.3–12 cm long, 2–6.5 cm wide, base truncate to cordate, margins coarsely apiculate-dentate or bidentate, apex obtuse to subacute or acuminate, sometimes with 2 (or very rarely 4) much smaller lateral lobes, finely pubescent, mostly on veins, especially beneath, to glabrous or almost so, narrowly petiolate with the petiole auriculate at the base. Capitula discoid, numerous in divaricately-branched terminal and axillary corymbs forming large, lax, pendent thyrsoid panicles; involucre cylindrical, 4–5.5 mm long, 2.5–3.5 mm in diameter; bracts of calyculus 3–5, lanceolate to broadly lanceolate, 1.5–2 mm long, floccose or ciliate or glabrous; phyllaries 8–13, green, 3.5–5 mm long, sparsely pubescent or glabrous. Ray florets absent; disc florets pale creamy yellow to yellow, corolla 3–5 mm long, tube expanded above the middle, glabrous, lobes 1–1.2 mm long. Achenes 2.5–3 mm long, ribbed, hairy; pappus white, 3–5.5 mm long.
