cauline Ivs. linear, slightly carinate, 3-5-pitted: infl. 

 2-6-fld., borne on very slender sts. which are glandular 

 below and sparsely glandular or glabrous above: fls. 

 white; calyx glabrous, the lobes ovate, obtuse, slightly 

 cartilaginous at their tips; petals subrotund-obovate, 

 5-nerved, the nerves straight, twice as long as the 

 calyx-lobes. May- Aug. Mountains of Eu. G.L. 28: 

 -A small species useful in alpine-gardens in a 

 sunny spot. It likes to be firmly wedged between 

 stones with sufficient earth for its root-development.

 pitose, about 3 in. high, with curved, woody, imbri- 

 cate-foliose caudicles: Ivs. of the caudicles densely con- 

 gested, gray or light gray-green, arched-recurved from 

 the base, linear-oblong, rather acute, near the margin

 and obtusely carinate dorsally, crustate with lime when 

 young; cauline Ivs. narrowly spatulate, slightly carinate,

 of the most commonly cult . Very variable and the parent 

 of many hybrids. Some of the varieties in cult . are : Var. 

 Bdydii, Hort., equals both S. Bbydii and S. Boydii var. 

 alba, Var. crenata, Hort., a form with crenate petals, 

 close to var. major. G. 36:289. Var. elegans, Hort., 

 equals S. Irvingii. Var. gloria, Hort., is a large-fld. 

 form with fl.-sts. l%in. high: peduncles rich red: fls. 

 pearly white, of a satiny texture, over 1 in. diam.; 

 petals with crimped edges. G. 31:252; 35:177; 36:288. 

 Gn. 78, p. 81. G.M. 50:213. Var. grandifidra, Hort., 

 is practically identical with var. gloria. G.M. 57:185. 

 Var. macrantha, Hort., has minute rosettes which are 

 very dense and form a cushion-like mound: fl.-sts. red- 

 dish, 1 in. high: fls. white and saucer-like. April. Var. 

 magna, Hort., is distinguished from var. major by 

 having a very densely tufted habit: Ivs. spin}', glaucous: 

 peduncles 3 in. high and 1-fld., reddish: fls. white, more 

 than 1 in. across, even larger than var. gloria. G.C. III. 

 47:164. Var. magnifica, Hort., grows about 1J4-2 in. 

 high with small dense rosettes of subulate gray Ivs.: 

 scape 1-fld.: fls. have huge, orbicular petals which are 

 white and deeply crenate and the disk is of a paler yellow 

 than that of var. major. April, May. Gn.W. 20:203; 

 26:251. Var. major, Hort., is less cushion-like in habit, 

 has pronounced silvery rosettes twice as large as the 

 type, reddish scarlet fl.-sts. 3 in. high, and fls. about 1 

 in. diam. with crimped white petals. Feb. Austrian 

 Alps. G.C. II. 21:141. G. 31:253. Gn. 63, p. 75. Var. 

 TniniTn > Hort., is said to have diminutive white fls. Var. 

 minor, Hort., is mentioned in connection with S. 

 Paulinx as one of the parents of that hybrid. Var. 

 rosea, Hort., equals S. Irvingii. Var. speciosa, Hort., has 

 bright red scapes bearing solitary fls. which are larger 

 and later than the type; the petals are^pure white, 

 broad and almost round. Var. tridentina, Jenkins 

 (var. tridentata, Hort.), is more tufted than var. major, 

 the fl.-sts. more richly scarlet and the fls. less notched 

 at the margins, the petals reflexed, white. Jan., Feb. 

 Dolomites. G. 37:379.

 the lower imbricate, spreading, lanceolate, acuminate, 

 stiffly mucronate, the entire margin ciliate-denticulate, 

 carinate, 3-5 minute pits (noticeable when old) near 

 the cartilaginous margin; cauline Ivs. lanceolate, 

 mucronate : infl. corymbose-paniculate from the middle 

 or upper part of the glabrous sts. : fls. small, light or rich 

 orange-yellow; calyx glabrous, lobes ovate, entire and 

 obtuse; petals spatulate-oblong, 3-neryed, the lateral 

 nerves bowed. June. Macedonia. Fine for covering 

 moist stony banks in the rock-garden. Var. specidsa, 

 Hort., is offered in the trade as a form with fine yellow 

 fls.
