SEDUM 



SEDUM 



sepals ovate-lanceolate, fleshy; petals lanceolate; 

 stamens yellow. China. Var. carneum, Hort. (S. 

 cdrneum variegatum, Hort.), has pink sts.: Ivs. with a 

 marginal stripe of white or cream-color. A good green- 

 house plant and also good for edging. 



8. Forsterianum, Smith. Perennial, forming small 

 tufts, glabrous or slightly glaucous: Ivs. of the barren 

 shoots many-ranked, forming 

 terminal rosettes, oblanceolate 

 or lanceolate, flattened but sub- 

 terete, spurred at the base: fls. 

 yellow, in a compact, round- 



3583. Stonecrop, or wall pepper. Sedum acre. 

 (X?fl 



topped cyme; sepals ovate; 



petals lanceolate. England. 



This is now kept distinct, 



but it has been referred to S. rupestre and also to S. 

 pruinatum, a species which does not seem to be in cult, 

 and it has also been treated as a variety of both these 

 species. Var. glanduliferum, Hort., is offered in the 

 trade. 



9. rupestre, Linn. Perennial, glaucous, reddening 

 with age and drought: barren shoots numerous, creep- 

 ing, 1-3 in. long; fl.-sts. ascending or erect, 6-12 in. 

 high: Ivs. ^in. long, in numerous rows, linear, subulate, 

 incurved, flattened above, forming dense conical 

 rosettes which are %-l in. diam., at the ends of the 

 sterile shoots : fls. numerous, yellow, barely %in. across, 

 5-7-merous, in umbellate, 3-5-forked, ultimately hol- 

 low-topped cymes; sepals ovate, oblong; petals ovate, 

 oblong; anthers yellow. W. Eu. Closely allied to and 

 confused with S. reflexum. Var. spirale, Hort., is 

 offered in the trade. 



10. reflexum, Linn. (S. colllnum, Willd.). Perennial, 

 glabrous: sts. trailing; fl.-sts. erect, 8-10 in. high: Ivs. 

 in 6 or 7 rows, crowded on the barren shoots into a 

 conical mass, but not forming so marked a rosette as in 

 typical S. rupestre, %~%in. long, linear-subulate, 

 reflexed, terete, gibbous at base: fls. 4-8-merous, yellow, 

 %in. across, in a decurved, many-fld. umbellate cyme 

 which is many-branched, with a fl. in each fork; sepals 

 oblong-lanceolate; petals linear; anthers yellow. Eu. 

 Also escaped in N. E. N. Amer. Var. albescens, Mast. 

 (S. albescens, Haw. S. glaucum, Smith), is glaucous: 

 Ivs. rarely in rosettes: fls. J^in. across, 6-merous. Eu. 

 and N. Afr. Var. cristatum, Mast. (S. monstrosum, 

 Hort. S. robustum, Hort.), has the sts. fasciated so as 

 to form a crest like a cockscomb. Var. virescens, Mast. 

 (S. virescens, Willd.), is similar to var. albescens, but 

 has pale sulfur-yellow fls. This species and its 

 varieties are treated by some authorities as a part 



of S. rupestre. 



11. anglicum, Huds. Perennial, about 

 3 in. high, glabrous, evergreen: barren 

 shoots trailing or erect, forming dense 

 masses; fl.-sts. about 2 in. high: Ivs. 



crowded, alternate, on the fl.-sts. some- /^ 3584 Sed 

 what opposite and less crowded, Yy- /If caenileum. 

 J^in. long, ovate or ovate-lanceolate, \ * (Natural size) 

 green, becoming red-tinged: fls. white 

 or rosy tinted, about %in. across, in 



few-fld. dichotomous cymes ; sepals ovate ; petals lanceo- 

 late; anthers red, becoming black. W. Eu. Gn. 79, p. 

 366. A good plant for the rockery, though rather 

 difficult to grow. 



12. caeruleum, Linn.; also spelled coeruleum (S. 

 azureum, Desf.). Fig. 3584. Annual, gfabrous, or pilose 

 in the infl.: sts. 2-3 in. high, branched from the base: 

 Ivs. tufted, Kin. long, oblong, obtuse, pale green, 

 spotted with red: fls. pale blue to rose-lilac, Kin. across, 

 577-merous, in a lax, many-fld. cyme, which is 1 in. 

 diam.; sepals oblong; petals oblong; anthers reddish 

 brown. Medit. region. B.M. 2224. B.R. 520. Gn. 27, 

 p. 315. Said to thrive in a sandy soil, and 

 to be adapted to carpet-bedding. 



13. brevifdlium, DC. Perennial, said to 

 grow about 4 in. high, glaucous, tufted: 

 Ivs. crowded in 4 rows, about Am. long, 

 ovoid, subglobose, pinkish, densely mealy 

 pubescent: fls. white, Kin. across, in an 

 umbellate, 2-3-forked cyme, with a pedi- 

 cellate fl. in the center of each fork; sepals 

 oblong-lanceolate, whitish with a pink 

 midrib; petals oblong, with a pink midrib; 

 anthers pink. France and Medit. region. 

 Closely related to S. dasyphyllum of 

 which some authorities have made it a 

 variety. Rather tender and sensitive to root-moisture. 

 Var. album, Hort., is said to have bronzy Ivs. and to 

 grow 6 in. high. Var. Pdttsii, Hort., is offered in the 

 trade as a form with tiny round Ivs., covered with 

 white meal. 



14. farinosum, Lowe. Perennial, glaucously prui- 

 nose, glabrous: sts. tufted, creeping, much branched: Ivs. 

 crowded in 4-6 rows, deciduous, % x Kin., oblong, very 

 obtuse: fls. white or flesh-color, nearly sessile, J^in. 

 across, crowded in a 2-3-parted cyme, 5-7-merous; 

 calyx-tube very short, segms. linear-oblong, pink- 

 tipped; petals lanceolate, acute, keeled; anthers pur- 

 plish brown. Madeira. Masters says that most of the 

 material cult, under this name is really S. album. 



15. dasyphyllum, Linn. (S. glaucum, Lam.). Peren- 

 nial, about 2-4 in. high, glabrous: sts. tufted, slender, 

 branching: Ivs. crowded, sessile, spreading, oblong- 

 acute or suborbicular, thick, studded with crystalline 



pimples: fls. white to pink- 

 ish, about Min. across, in 

 lax, few-fld., corymbose 

 cymes; sepals oblong, 

 fleshy; petals lanceolate; 

 anthers black. Eu., N. 

 Afr. The material cult, 

 under the name of S. 

 glaucum probably belongs 

 here; see also S. rupestre 

 and S. hispanicum. Var. 

 glanduliferum, Moris (S. 

 cdrsicum, D u b y ) , has 

 minute gray -green Ivs. 

 which are more or less 

 densely glandular - pubes- 

 cent: fls. white. Corsica 

 and N. Afr. B.M. 6027. 

 There is a form of this 

 offered in the trade under the name 

 of S. corsicum var. grandiflbrum, 

 Hort. 



16. potosinum, Rose. Sts. low and 

 weak, at first erect, but soon prostrate or at 

 most ascending; fl.-sts. 2-4 in. high, slender: Ivs. 

 crowded, rhomboid-subspherical, nearly terete, 

 K-^HI. long, obtuse, pale green, glabrous, 

 papillose(?), slightly glaucous: fls. white or tinged 

 pink, terminal and few; sepals linear; petals 

 lanceolate, acuminate, widely spreading. Mex'. 

 A rare species.
