12-14 in. diam. and very profusely fld. panicles which 

 attain a length of 2 ft. and a diam. of 16 in. The fls. 

 are white. G.C. III. 53:390 (as S. longifolia). Gn. 77, 

 p. 298; 79, p. 30. 



67. lingulata, Bell. Fig. 3561. One to 2 ft. high with 

 ascending branched caudicles which are covered with 

 appressed vestiges of Ivs. and form a cespitose clump: 

 sts. erect or ascending, usually glabrous or sometimes 

 sparsely glandular-pilose, leafy: basal Ivs. numerous 

 and rosulate, sulcate above, usually linear-spatulate and 

 rather acute, somewhat ciliate, margin erose-crenulate 

 and crustate with lime; cauline Ivs. shorter, the margin 

 cartilaginous and less crustate: infl. a thyrsoid panicle 

 from the middle of the scape or above, the branches 

 slender, corymbose-paniculate at their tip, 3-5-fld., very 

 often secund: fls. small, white; calyx glabrous, the lobes 

 ovate or oblong, very obtuse ; petals obovate or obovate- 

 oblong, attenuate toward the base, 3-nerved, 2 or 3 

 times longer than the calyx-lobes. June, July. S. Eu. 

 B.M. 8434. Gn. 79, p. 188. G.C. III. 49:65, note. A 

 variable species requiring lime and good drainage. Var. 



Alberti, Hort. (S. Alberti, 

 Regel & Schmalh.), is proba- 

 bly a hybrid: it has much 

 larger rosettes and the infl. is 

 more spreading: fls. white, 

 heavily spotted red. Turk- 

 estan. Var. australis, Engl. (S. 

 australis, Moric.), usually has 

 longer and broader spatulate 

 Ivs. which are nearly flat on 

 the top. Italy and Sicily. Var. 

 Bellardii, Hort., equals the 

 type. G.C. III. 54:135. Var. 

 lantoscana, Engl. (S. lantos- 

 cdna, Boiss. & Reut.). Lvs. 

 short, blunt, spatulate, more 

 or less attenuate at the base 

 but not so at the 

 apex; margin nar- 

 rowly crustate. 

 Maritime Alps. G. 

 C. II. 15:109. Gn. 

 64, p. 61; 73, p. 55. 

 Minor forms of this 

 variety are cult., as 

 S. lantoscana erecta, 

 having pure white 

 fls., and S. lantos- 



3561. Sarifraga lingulata. fdna superba hav- 



ing arching plumes 



of creamy white fls. larger than those of the variety 

 proper. 



68. catala&nica, Boiss. & Reut. Densely cespitose, 

 1-2 ft. high: Ivs. of the rosette, which grows to be 3 in. 

 diam., erect-spreading, qbovate-ligulate, rather obtuse, 

 margin subentire and white-crustate, glabrous, glaucous, 

 subcanaliculate above; the cauline Ivs. few, obovate- 

 oblong: inn. a slender-branched cymose panicle borne on 

 an erect few-lvd. fl.-st. with erect bracteolate slender 

 glandular-viscid pedicels, which are longer than the fls. : 

 fls. white; sepals oblong, obtuse, glabrous, longer than 

 the glandular tube of the calyx; petals spatulate-oblong, 

 3 times as long as the sepals. May, June. Spain. Gn.W. 

 25:125. By some considered only a variety of S. 

 lingulata. 



69. cochlearis, Reichb. (S. lingulata var. cochlearis, 

 Engl.). Six to 9 in. high, densely cespitose, with short 

 much-branched caudicles covered below with withered 

 Ivs.: Ivs. densely rosulate, spreading, J^-l in. long, 

 linear at their base, toward the top spreading into a 

 rounded or spatulate blade, glaucous, coriaceous, margin 

 cartilaginous and crustate with lime; the cauline Ivs. 

 small, linear, acute, red-brown: infl. paniculate, erect 

 and open, either thyrsoid or subcorymbose, borne on 



very slender bright red-brown fl.-sts. : fls. white, Vz-% 

 in. diam.; calyx red-brown, the lobes small, ovate, 

 obtuse; petals obovate, apex rounded. June, July. 

 Maritime Alps. Eu. B.M. 6688. G.C. III. 44:245; 

 51:174. Gn. 74, p. 326. Var. major, Hort., has much 

 larger rosettes of Ivs. and taller sprays of fls. It is sug- 



gsted that it may be of hybrid origin. Var. minor, 

 ort. (S. Probynii, Correv.), has minute rosettes of 

 silvery Ivs. and much shorter sprays of fls. which are 

 white. Apparently some of the material grown as S. 

 valdensis is referable to this. 



70. crustata, Vest (S. incrustata, Vest). About 1-3 

 in. high with ascending branched caudicles which are 

 covered with appressed vestiges of Ivs. and form ces- 

 pitose clumps up to 4 or 5 in. diam.: sts. ascending, 

 densely glandular-pilose : basal Ivs. light gray-green, the 

 lower third pink, sulcate, linear, obtuse, minutely 

 crenulate with the crenatures very close together, crus- 

 tate with lime, ciliate toward the base; cauline Ivs. 

 few, linear-lanceolate, serrate, glandular at base: infl. 

 a scape, racemose from the middle or above, the 

 branches 1-fld. or paniculate 3-6-fld.: fls. yellowish 

 white sometimes purple-dotted toward the center; 

 calyx sparse-glandulose at base, the lobes oblong- 

 triangular with membranaceous margins; petals obo- 

 vate, base scarcely attenuate, almost 3 tunes as long 

 as the calyx-lobes. June. Tyrol. Easy to grow and 

 adapted to a shady location; scarcely known in Amer. 



71. H&stii, Tausch (S. elatior, Mert. & Koch. -S. 

 Aizodn var. Hostii, Hort.). Cespitose, 6-18 in. high: sts. 

 erect, rather stout and glandular-pilose: basal Ivs. 

 numerous, rosulate, rather erect, ungulate with an 

 obtuse apex and ciliate base, margin crenulate, the cre- 

 natures truncate; cauline Ivs. oblong, rather obtuse, 

 crenate-serrate; bracts oblong-linear, glandular ciliate: 

 infl. a scape, paniculate above the branches, elongated, 

 naked and densely glandular-pilose; the pedicels densely 

 short-glandular: fls. white, often with numerous purple 

 dots toward the center; calyx-lobes ovate-triangular; 

 petals oblong or obovate-oblong, double the length of 

 the calyx-lobes. May-Aug. Mountains of Cent. Eu. 

 A strong grower and said to produce offsets very freely 

 and in this way spread rapidly. Var. rhaetica, Engl., 

 also spelled rh&tica (S. rhastica, Kerner). Basal Ivs. 

 linear-lingulate, apex rather acute: petals obovate- 

 oblong, white with numerous purple dots above the 

 middle. Mountains of Austria. 



72. altissima, Kerner (S. Hdstii var. altissima, 

 Hort,). Fig. 3558. Cespitose, 1-2 ft. high: sts. erect, 

 stout, glandular-hirsute: Ivs. thick, the basal spread- 

 ing, broad, tongue-shaped, rather acute, base ciliate, 

 margin serrate, serratures acute and cartilaginous; 

 cauline Ivs. oblong, rather obtuse, serrate; bracts 

 oblong-linear or linear, obtuse and glandular-pilose 

 ciliate: infl. a scape racemosely paniculate above, 

 the branches about 10-fld. and densely glandular- 

 pilose; pedicels densely short-glandular: fls. white, their 

 base greenish and purple-dotted toward the center; 

 calyx-lobes ovate, obtuse, cartilaginous margined; 

 petals elliptic, 3-nerved, twice as long as the calyx- 

 lobes. Tyrol. Very closely allied to S. Hostii, possibly 

 not specifically distinct. Little known in Amer. out- 

 side fanciers' collections. 



73. Aizdon, Jacq. (Chondrdsea Aizdon, Haw.). Fig. 

 3562. Perennial, cespitose, 4-20 in. high: sts. erect, 

 foliose: basal Ivs. curved, thick, rather flat above, 

 smooth, the base ciliate. margin serrate, many-pored, 

 more or less crustate with lime, serratures cartilaginous 

 at the apex and antrorsely acuminate; cauline Ivs. 

 smaller, cuneate or spatulate, base glandular-ciliate : 

 infl. a scape, corymbose-racemose, corymbose-panicu- 

 late or paniculate above, the branches 3-5-fld., more or 

 less glandular-pilose, rarely glabrous: fls. cream-colored,
