later opening than the type. Var. pallida, Hort., a form 

 said to have pale yellow fls., is offered in the trade. 



119. pungens, Slinderm. (S. Rocheliana x S. junip- 

 erifolia). In general appearance it is similar to the 

 latter parent, with rather smaller rosettes of dark green, 

 sharp-pointed Ivs., but with the more compact habit of 

 S. Rocheliana. Its. fl.-sts. are about 1-2 in. high, glan- 

 dular-hairy and tinged red-brown, bearing several deep 

 golden yellow fls. which are larger and paler than those 

 of S. juniperifolia. A garden hybrid. 



120. Borisii, Kellerer (S. marginata x S. Ferdinandi- 

 Coburgi). It more closely resembles the latter parent. 

 About 2-3 in. high with large rosettes of silvery Ivs.; 

 bracteate, glandular sts. each bearing 4 or 5 large yel- 

 low fls. which are paler than S. Ferdinandi-Coburgi. A 

 garden hybrid raised in Sofia, Bulgaria. S. Kyrillii is 

 another product of the same cross. 



121. Kyrillii, Kellerer (S. marginata x S. Ferdi- 

 ndndi-Cdburgi). Another product of the same cross as 

 S. Borisii but more closely resembling the former par- 

 ent. The Ivs. show the chalk-pits more distinctly; the 

 green, glandular sts. are about 3 in. high and bear pale 

 yellow fls. which are lighter and usually larger than 

 those of S. marginata. March. A garden hybrid, raised 

 at Sofia, Bulgaria. 



122. Sundennannii, Hort. (S. marginata x S. Bur- 

 seriana). A smaller plant than S. Obristii (a result 

 of the reciprocal cross) and resembling the latter 

 parent more closely. About 2-3 in. high, habit tufted 

 and free-growing, the rosettes larger than in S. Obristii, 

 %in. diam.: Ivs. M m - l n g> broadest at the base and 

 tapering to a point as in S. Burseriana, upper surface 

 channeled or concave and covered with a chalky deposit 

 on the margins and apex: infl. 1- or 2-fld., borne on 

 green fl.-sts. which are obtuse, bracted, and covered with 

 glandular white hairs: fls. white, %in. across; sepals 

 obtuse, tinged red-brown and glandular; petals with 

 crisped margins as in some forms of S. Burseriana and 

 double the length of the sepals. A garden hybrid. G.C. 

 III. 49:228. Very free-flowering. 



123. Petraschii, Sunderm. (S. tombeanensis x S. 

 Rocheliana}. Of neat habit and very free-flowering. 

 The plant has compact cushions of glaucous Ivs. in 

 rosettes: sts. about 2 in. high, glandular and red-tinged, 

 bearing heads of 3-5 large white fls. which are 1 in. 

 across. March, April. A garden hybrid. G.C. III. 

 49:172. G. 33:231. Gn. 75, p. 190. G.M. 54:201 

 Does best on a soil which has been liberally mixed with 

 pieces of sandstone. 



124. kestoniensis, Hort. Supposed to be a seedling 

 of S. Burseriana, though by some said to resemble S. 

 scardica var. obtusa more closely. It has very white 

 fls. which come very early and are starry. The fl.-sts. 

 are bright red and about 3 in. high. Jan.-March. A 

 garden hybrid. 



125. B6ydii, Dewar (S. Burseriana x S. aretioldes. 

 S. Burseriana var. Bdydii, Hort.). Plant tufted, gray 

 and very slow-growing, fairly intermediate: Ivs. more 

 nearly resembling S. Burseriana, but instead of taper- 

 ing to an acute point they are linear with an abrupt 

 point: infl. 1-3-, rarely 4-5-fld.: fls. almost as large as 

 those of S. Burseriana, but yellow as in S. aretioides. 

 March. A garden hybrid. G.C. III. 39:250. G. 32: 333. 

 G.M. 53:317. 



Var. alba, Hort. (S. Burseriana var. Boydii, Hort.). 

 A plant which very little resembles S. Boydii and by 

 some is thought to be a hybrid (S. Rocheliana var. 

 coriophylla x S. Burseriana) . Lvs. subulate, arranged in 

 small rosettes which form dense cushions: fls. white, 

 borne on scapes about 2 in. high, bearing a cyme of 3-4 

 fls. Gn. 71, p. 178; 72, p. 177. It resembles S. Burseri- 

 ana in many respects but differs in having larger Ivs. 

 and more fls. to a scape. Var. kestoni, Hort., is offered 

 in the trade, possibly the same as S. kestoniensis. 



126. Faldonside, Boyd (S. Burseriana x S. areti- 

 oides). Lvs. silvery: st. suffused with pink: fls. lemon- 

 yellow, borne in 2's or 3's, %in. diam., of beautiful form 

 with full overlapping petals which are crimped at the 

 edges; the small orange-colored glandular disk in the 

 center of the fl. adds to its attractiveness. Feb., March. 

 A garden hybrid. Free-flowering. The same cross as 

 S. Boydii but freer growing and with larger fls. of a 

 better form. 



127. SalomSnii, Siinderm. (S. Burseriana x S. Rochel- 

 iana. S. salmonica, Hort.). The habit is more that of 

 the former but the infl. and stronger growth that of 

 the latter parent: rosettes usually J^in. diam.; Ivs. awl- 

 shaped, 3-cornered with cartilaginous margins and 

 decidedly glaucous: fl.-sts. 1^-2 in. high, tinged red, 

 pubescent and covered with Ivs.; fl.-buds suffused with 

 pink, but fls. white, more the substance of S. Rochel- 

 iana and borne 3 or 4 to a st., about Min. across. Feb., 

 March. A garden hybrid. Gn.W. 22:291. 



128. Obristii, Sunderm. (S. Burseriana x S. mar- 

 ginata) . A robust plant, about 3-4 in. high, with rosettes 

 about %in. diam.: sts. glandular and tinged red-brown: 

 Ivs. strap-shaped, acute, with 4 or 5 chalk-pits on their 

 margins: fls. 2-4 to a st., large, almost 1 in. across, 

 ivory-white; petals broad, rounded and overlapped as 

 in S. marginata. March. A garden hybrid. G.C. III. 

 49:229. It is very like an enlarged S. Burseriana in 

 general appearance though the foliage is intermediate 

 and the fls. resemble S. marginata. Another distinct 

 form resulting from this cross is S. Sundermannii. 



129. Elizabethae, Sunderm. (S. Burseriana x S. 

 sdncta. S. Cherrytrees, Hort.). Very free-growing, form- 

 ing cushion-like tufts: Ivs. deep green, in small rosettes 

 which are closely packed together: fl.-sts. 2 in. high, 

 tinged red, glandular; the bracts tipped with green: fls. 

 yellow (variously stated as sulfur, primrose, and canary), 

 quite large and in heads of 3-5. March, April. A gar- 

 den hybrid. G.L. 18:116; 25:153. 



130. Irvingii, Hort. (S. Burseriana var. macrdntha x 

 S. Fnderici-Augusti. S. Burseriana var. elegans, Hort. 

 S. Burseriana var. rosea, Hort.). This partakes more 

 of the character of the former, with similar tufts of 

 foliage and single fls. The latter parent shows in the 

 color of the fls. which are blush-pink, deeper at the 

 center. The fl.-sts. are only 1 in. or so high and the 



Slant is very free-blooming. March. A spontaneous 

 ybridatKew. G.C. III. 57:158. G. 37:187. Gn. 76, 

 p. 193; 79, p. 152. G.M. 58:149. S. kewensis is 

 another product of the same cross but more allied to 

 S. Friderici-Augusti. 



131. kewensis, Hort. (S. Burseriana var. macrdntha 

 xS. Fnderici-Augusti). About 2-3 in. high with the 

 Ivs. of the latter parent but the cushioned habit of the 

 former: sts. pale glandular-hairy; bracts red tipped with 

 green: fls. intermediate in shape; sepals deep red and 

 glandular, while the petals are rose, much deeper 

 colored toward their base. March. A garden hybrid. 

 G.C. III. 51:247. 



132. bursiculata, Jenkins (S. Burseriana var. major 

 xS. apiculata). Plant about 3 in. high, with silver- 

 gray rosettes: Ivs. acutely pointed, glaucous and similar 

 to the former parent, while the horizontal spread of the 

 rosettes and their size show the influence of S. apiculata: 

 fl.-sts. 3-4-fld.: fls. large and white. March. A garden 

 hybrid. G.C. III. 49:158. G. 33:183. Gn. 75, p. 155. 

 G.M. 54:188. J.H. III. 62:357. 



133. Paulinae, Sunderm. (S. Burseriana var. minor 

 xS. Ferdinandi-Coburgi). Habit compact, nearer like 

 that of the latter parent, about 2 in. high, with larger 

 rosettes of glaucous foliage: sts. tinged with red and fls. 



Kale yellow, about %in. diam. March. A garden 

 ybrid. Somewhat resembles S. Elizabethae, but the 

 foliage is more glaucous and the rosettes are smaller. 

 Var. compacta, Hort., is said to have compact cushions
