shoots: Ivs. mostly basal, in a rosette (a few cauline), 

 imbricated, oblong-ovate, glabrous and fleshy: infl. 

 1-3-fld., terminal on filiform, glandular-pubescent 

 peduncles: fls. large, yellow; calyx-lobes ovate or 

 oblong-ovate, obtuse; petals oval to broadly obovate, 

 much longer than the calyx-lobes. Mountains of Colo, 

 and New Mex. Has been offered by dealers in native 

 plants. 



56. aspera, DC. More or less cespitose, 4-6 in. high, 

 with prostrate, mostly dark purple caudicles: fl.-sts. 

 erect or ascending, remotely Ivd.: Ivs. pale green, 

 shiny, lanceolate-linear, spiny-aristate and ciliate, those 

 of the caudicles bearing buds in the axils: infl. 1-fld. or 

 few-fid, panicles, on glabrous peduncles: fls. yellowish 

 white; calyx sparsely glandular below, the lobes ovate- 

 triangular mucronulate; petals oblong or obovate- 

 oblpng, 3-nerved, double the lengths of the calyx-lobes, 

 oblique truncate. May, June. Mountains of Eu. 

 A rock-loving species suitable for rockeries and alpine 

 gardens, best grown in a moist but well-drained spot. 

 Little known in Amer. yar. bryoides, DC. (S. bryoldes, 

 Linn.). Lvs. of the caudicles very dense, slender ciliate, 

 the apex incurved; the cauline Ivs. subapproximate, 

 erect, appressed to the sts. which are 2-3 in. high and 

 1-2-fld. 



57. bronchialis, Linn. Dwarf, cespitose, 4-8 in. high: 

 sts. ascending, densely foliose at the base; fl.-sts. few- 

 lyd.: Ivs. stiffish, almost leathery, gray-green, shiny, 

 linear-lanceolate, margin ciliate or spinulose: infl. few 

 or many-fld., paniculate, borne on erect-spreading 

 glandulose pedicels: fls. yellowish white with orange- 

 red dots; calyx-lobes oblong-lanceolate, rather obtuse, 

 glabrous; petals oblong, 3-nerved, twice as long as the 

 calyx-lobes. May. Asia and Alaska. The material 

 from the Cascade Mts. of Wash, to Alberta and south- 

 ward along the Rocky Mts. to New Mex., which has 

 passed as S. bronchialis, has been separated under the 

 name of S. austromontana, Wiegand (S. bronchialis, 

 Pursh, not Linn. Leptdsea austromontana, Small). It 

 differs from S. bronchialis in its more subulate, darker 

 green Ivs., more slender often purple sts., more slender 

 pedicels, smaller white petals with purple dots above 

 and not clawed at the base. S. austromontana is proba- 

 bly not in cult.

 cherlerioldes, Small). Densely cespitose, with the cau- 

 dicles very densely imbricate-leafy: Ivs. short, flat 

 above, convex below, somewhat spatulate, acute- 

 mucronate: fl.-sts. shorter, 2-3 in. high, few-fld., 

 glandulose or glabrous: fls. white; calyx-lobes rather 

 obtuse. May. Asia and N. Amer., Unalaska, Bering 

 Straits.

 with white hairs: infl. paniculate-corymbose, borne on a 

 densely glandular fl.-st. which is naked above; pedicels 

 bracteolate at their base: fls. yellow to white; sepals 

 lanceolate, glabrous or glandulose, scarcely or not 

 spreading; petals oblong, obtuse, abruptly attenuate 

 to a long claw, twice as long as the sepals. July-Sept. 

 China. 



59. aizoides, Linn. (Leptdsea aizoides, Haw.). Loosely 

 cespitose, 2-6 in. high, with decumbent or ascending, 

 foliose, glabrous or sparsely very short pilose caudicles 

 which are branched from the base: Ivs. green or red- 

 dish, the lower linear or linear-oblong, mucronate, flat 

 below, above slightly convex, glabrous or more or less 

 rigid-ciliate ; the upper rather remote, smaller, oblong, 

 rather obtuse, rarely ovate: infl. 1-fld., often many-fld., 

 racemose, .borne near the top of the st. on axillary 

 peduncles: fls. yellow, more or less spotted with orange; 



calyx-lobes oblong-triangular, obtuse, spreading; petals 

 oblong, 1-nerved, 1^ times as long as the calyx-lobes. 

 June-Aug. Eu., Asia, arctic Amer., south to Gulf of 

 St. Lawrence, mountains of N. Vt., W. N. Y., and 

 the Lake Superior region. B.B. 2:171; (ed. 2) 2:217. 

 (The Rocky Mt. form has been segregated as S. 

 Van-Bruntise, Small.) Usually found in stony places 

 where there is trickling water. Very easy to grow 

 and may be divided almost any time. Var. aurantiaca, 

 Hort., is a form with the fls. described as of "old- 

 gold passing off to a kind of coppery red." Var.

 spinulose-ciliate : fls. rich crimson (Engler says orange- 

 red or cinnamon-colored) . Cent. Eu. 



60. cinerascens, Engl. & Irmscher. Densely ces- 

 pitose, 2-4 in. high, the caudicles prostrate, rosulate- 

 Ivd. : Ivs. of the caudicles rather stiff, linear-lanceolate, 

 margin cartilaginous and lax-ciliate or ciliate-spinulose, 

 apex tapering to a persistent awn, under surface shining, 

 whitish; the cauline Ivs. lanceolate, rather stiff, aristate, 

 margin densely short, black glandular-pilose: infl. 

 1-3-fld., on fl.-sts. which are often reddish their whole 

 length and black glandular-pilose as are the pedicels: fls. 

 golden yellow; sepals ovate, subacute, not reflexed; 

 petals obovate, narrowed to a stipitate base, 3-nerved,

 cels glandulose, the 

 latter 3 or 4 times 

 longer than the fls. :

 obtuse; petals ob- 

 long, obtuse, 3- 

 nerved, 3-4 tunes

 is not this species 

 but a variety of S. 

 leucanthemifolia. S. 

 Brunoniana spreads 

 freely by means of 

 its runners and likes 

 a moist spot. Not 

 commonly in cult.
