SENECIO 



SENECIO 



(Kleinia) Anteuphorbium, Schz. Bip., is sometimes seen 

 in collections, although it is not known to be in the 

 American trade. It is a glabrous shrub 3-4 ft. high, with 

 fleshy sts. constricted at the joints, small, erect, fleshy, 

 entire Ivs. that are decurrent on the st., and solitary 

 cylindric yellow-fid, heads (with rose tinge) an inch 

 long. B. M. 6099. According to J. D. Hooker, this 



3603. Senecio radicans. 



plant "is one of the oldest Cape plants in cult, having, 

 according to Dodonaeus, been brought to Eu. in 1570, 

 and cult, in England in Gerard's garden in 1596. The 

 name Anteuphorbium was given because of its being a 

 reputed antidote against the acrid poison of the Cape 

 Euphorbium." The names Kleinia spinidosa, K. pen- 

 dula, and K. suspensa have appeared in the American 

 trade, but they are unidentifiable. 



2. radicans, Schz. Bip. (Cacalia radicans, Linn. f. 

 Kleinia radicans, Haw.). Fig. 3603. Sts. prostrate, 

 readily rooting from the nodes: Ivs. fleshy, cylindrical, 

 straight or somewhat curved, 1 in. or less in length, J^in. 

 thick, acute, narrowed at the base into a short petiole: 

 peduncle terminal, bearing a single rayless head. S. 

 Afr. A desirable plant for the rockery; it grows freely 

 among cacti and other fleshy plants. 



3. mikanioides, Otto (S. scdndens, DC.). GERMAN 

 IVY. Fig. 3604. Slender and glabrous, tall-twining: Ivs. 

 ovate or deltoid-ovate in outline, mostly with a deep 

 basal sinus, sharply 5^7-angled or angle-lobed: heads 

 small, discoid, yellow, in close clusters on axillary and 

 terminal branches; bracts of the involucre shorter than 

 the disk-fls. S. Afr. G. 35:343. Very common con- 

 servatory and window-garden plant, easily prop, by 

 cuttings. 



4. scandens, Buch.-Ham., not DC. A hardy plant 

 with woody climbing sts. reaching a height of several 

 feet: branches slightly hirsute: Ivs. short-petiolate, 

 elliptic-lanceolate in general outline, undivided or bear- 

 ing two or more divisions at the base of the blade, tri- 

 angular-dentate, grayish green and finely pubescent on 

 both surfaces: infl. a terminal panicle; heads radiate, 

 rays commonly 8, yellow. China. R.H. 1909, p. 407.

5. macroglossus, DC. CAPE IVY. An herbaceous 

 glabrous climbing perennial: Ivs. petiolate, deltoid- 

 hastate, 1-1 Yi in. long and broad, usually with 2 sali- 

 ent acuminate basal lobes, entire or subdentate, cor- 

 date to almost truncate at the base: flowering branches 

 1-3-headed: heads radiate with 8-12 yellow rays; disk- 

 fls. 40-50: achenes glabrous. S. Afr. G. 26:26. A 

 coolhouse climber. 



6. auriculatissimus, Brit. A perfectly glabrous 

 climbing perennial, freely branching with divaricately 

 spreading branches: Ivs. petiolate, transversely oblong 

 to Gubreniform, 2-3 in. broad, coarsely crenate-dentate, 

 bright green above, paler beneath; petioles 1-2 in. long, 

 slender, channeled above, abruptly dilated at the base 

 into 2 broad auricles completely clasping the st.: heads 

 radiate, about 1 in. diam., disposed in loose terminal 

 corymbose cymes; ray-fls. about 13, rays yellow: 



achenes 5-ribbed, puberulent along the ribs. Brit. Cent. 

 Afr. G. C. III. 27:133, desc. B.M. 7731. On account 

 of the peculiar foliage and bright yellow fls. it is a 

 striking plant and well worthy of more general cult. 



7. elegans, Linn. (S. purpureus, Hort. Jacobsea ele- 

 gans, Moench). PURPLE RAGWORT. Annual, viscid- 

 pubescent, erect or diffuse, 1-2 ft. high: Ivs. various, 

 mostly oblong in outline, pinnate, lobed or toothed, the 

 sinuses chiefly broad and rounded, clasping at the base . 

 heads in loose corymbs, the rays purple; disk-fls. yellow. 

 S. Afr. B.M. 238. Var. erectus, Harv. St. slender but 

 erect: Ivs. pinnate or 2-pinnatifid. S. elegans is an 

 old garden plant. A common form of it has double fls. 

 Var. albus, Hort., has white fls. 



8. pulcher, Hook. & Arn. Robust, 2-4 ft. high, white- 

 cobwebby: st. simple or nearly so and scarcely leafy: 

 Ivs. oblong-lanceolate, 4-10 in. long, thick, shallow- 

 lobed and crenate-toothed: heads 2-3 in. across, with 

 many long, red-purple rays and a yellow disk. Uruguay 

 and Argentina. B.M. 5959. R.H. 1877, p. 94; 1896, 

 p. 329. Gn. 49, p. 122. G.M. 40:745. G. 31: p. 489, 

 desc. A very bold species, with striking erect habit 

 and large fls. in summer. Perennial, although it has 

 been described as annual. In protected places and well- 

 drained soils, it is hardy in S. New England. 



9. grandiflSrus, Berg. (S. venustus, Ait.). An herba- 

 ceous perennial 4-5 ft. high: st. simple or sparingly 

 branched, virgate, striate, glabrous or nearly so, rather 

 leafy except toward the infl.: Ivs. sessile, pinnately 

 parted into linear divisions with revolute margins, 

 glabrous or sparingly pilose: heads numerous, radiate, 

 strongly calyculate, disposed in a loose nearly naked 

 corymbose cyme; rays purple; disk-fls. yellow: achenes 

 striate, glabrous or puberulent in the furrows. S. Afr. 

 B.R. 901. Var. albidus, Harv. (S. dlbidus, Mey.). Both 

 ray- and disk-fls. pale or whitish. 



10. D6ria, Linn. Erect, 3-4 ft. high: radical Ivs. oval- 

 oblong or oblanceolate, 6-15 in. long, dentate, glabrous 

 and glaucous, gradually narrowed into a winged petiole; 

 st.-lvs. oblong-lanceolate, sessile and somewhat decur- 

 rent: heads yellow, with 5 or 6 rays. Eu. Hardy 

 perennial. 



11. macrophyllus, Bieb. (Jacobxa macrophylla, Mey.).

 6-48 in. long, 1-4 in. broad, gradually narrowed into a 

 winged petiole, pale green, not glaucous; upper st.-lvs. 



3604. Senecio mikanioides, usually called German ivy. ( X K) 



sessile, semi-amplexicaul and somewhat decurrent on 

 the st. : heads radiate, disposed in a terminal compound 

 cormybose cyme. Eu. Closely related to the preced- 

 ing. Not infrequent in European gardens and occa- 

 sionally offered in trade catalogues. Not the same as 

 LfiguLaria macrophylla, DC. ; see supplementary list.
