AA. BETWEEN SPECIES OF SECTION H. 



103. Vetteriana, Beauverd (S. hederacea x S. Huet- 

 iana). Lvs. intermediate between the two parents: fls. 

 sulfur-yellow or whitish, the size of those of S. Huetiana 

 and twice as large as those of S. hederacea; the petals 

 more elongated than those of the last-mentioned 

 species. June. Switzerland. A spontaneous hybrid 

 which appeared in the alpine garden of the Hortus 

 Boissierianus.

104. Andrewsii, Harv. (S. Geum x S. Aizoon. S. 

 Guthriedna, Hort., also spelled Guthriana and Gutherir 

 dna. S. acanthifolia, Hort. S. umbrosa var. acanthifolia, 

 Hort.). About 6 in. high: Ivs. rather thick, in loose 

 rosettes similar to 5. Aizoon, but much longer and more 

 or less Ungulate: fls. white, thickly dotted with red for 

 two-thirds the length of the petals. June. A sponta- 

 neous hybrid probably of garden origin. Gn. W. 25 : 598. 

 S. Guthrieana is credited to the Pyrenees. 



105. Engleri, Huter (S. Aizoon x S. cuneifblia). Lys. 

 elongate, obovate-oyal, the narrowed lower portion 

 ciliate. margin indistinctly crenate and obscurely pitted: 

 fl.-sts. about 4 in. high, glandular-hairy : infl. laxly 

 2-3-fld. : fls. very small. A garden hybrid. Quite 

 probably all of the material grown as S. 'Engleri is not 

 the same as another form, "with beautiful, long, sil- 

 vered Ivs. in handsome rosettes bearing upward of 20 

 handsome plumes of white fls. to a height, some of them, 

 of more than 1 ft.," which is mentioned in English 

 journals.

106. Dr. Ramsey, Hort. (S. longifolia x S. cochLearis). 

 Resembles the latter parent more, but both the spoon- 

 shaped Ivs., which take on a brilliant red tint in the 

 fall, and the infl. of white fls. are larger than in S. 

 cochleari^. The fls. are sprinkled with pink dots. A 

 garden hybrid. 



107. splendens, Hort. (S. longifolia x S. Cotyledon). 

 A showy plant about 1 ] o ft. high, with silvery rosettes 

 more like the former parent and the looser infl. of the 

 latter: fls. white. A garden hybrid. 



108. Burnatii, Siinderm. (S. cochledris x S. Aizoon). 

 Rather intermediate in character, but more nearly 

 approaching the former parent in its If.-rosettes and 

 the infl. of large white fls. A natural hybrid found in the 

 Maritime Alps. 



109. Grandfieldii, Hort. Said to have been raised 

 from 5. Aizoon var. rosularis, by some said to be more 

 probably raised from S. Aizoon var. lutea. The Ivs. are 

 ligulate, about 1 in. long and J^in. broad, encrusted and 

 form a basal rosette: fls. pure white, unspotted and 

 borne on stalks 15 in. high in spreading sprays. A 

 garden hybrid of English origin. G. 36:673. 



110. Gaudinii, Bruegg. (S. Aizoon xS. Cotyledon). 

 Also spelled Gaudiniana. Rosettes small and silver- 

 gray: the fls. white. Supposed to be a spontaneous 

 hybrid. Eu. 



111. Macnabiana, Hort, (S. Cotyledon x S. Hbstii. 

 S. Hostii var. Macnabiana, Hort.). The rosettes of 



Ivs. are intermediate in character, but the Ivs. are much 

 smaller than in S. Cotyledon and the plant is seldom 

 more than 1 ft. high, more or less branched above: fls. 

 numerous, white, heavily speckled with pink to purple 

 dots, the spots large. Mav, June. A garden hybrid. 

 Gn.W. 20:868. J.H. HI. 57:61. 



AAAAA. BETWEEN SPECIES OF SECTION TTTT. 



112. ambigua, DC. (S. media x S. aretundes). About 

 2J^ in. high with reddish or purplish glandular fl.-sts. : 

 Ivs. linear, nearly obtuse and a little reflexed: fls. pur- 

 ple, red or coppery, with the petals a little longer than 

 the calyx-lobes. Pyrenees. G.C. III. 54:183. One of 

 three native hybrids resulting from this cross. S. 

 ambigua comes nearest to S. media, with red sepals and 

 petals; S. luteo-purpurea, Lapeyr, is intermediate 

 between the parents and has red sepals and yellow 

 petals; while S. Lapeyrousii, Don, resembles S. areti- 

 oides more closely; its sepals are green and its petals 

 yellow. 



113. aurantiaca, Hort. (S. media x S. aretioides). 

 More nearly resembling S. aretioides but the rosettes 

 are larger: fls. yellow. Very similar to S. luteo-purpurea, 

 Lapeyr. 



114. intermedia, Hort. (S. Grisebdchii x S. Strib- 

 nryi. S. Grisebdchii var. intermedia, Hort.). Very 

 similar in all respects to the former, but with a racemose 

 infl. instead of a spicate one, the pedicels longer than 

 those of S. Grisebachii: fls. red. Probably a natural 

 hybrid. G.C. IU. 46:195. 



115. Bertolonii, Sunderm. (S. Fnderici-Augusti x S, 

 porophylla). Nearer the former parent in habit, about 

 3 in. high, the rosettes of Ivs. IJi in. diam.; Ivs. long, 

 narrow, and pointed, with the chalk-pits very evident : 

 infl. a nodding raceme borne on a red st. with red 

 leafy bracts which are tipped with green: fls. red, on 

 short pedicels. A garden hybrid. Does well in a crev- 

 ice or on a ledge, but requires lime. 



116. Kellereri, Sunderm, (S. Fnderici-Augusti x 

 probably a form of S. Burseridna). Inclined in habit to 

 the former, with well-developed rosettes which are 

 nearly 2 in. diam., but the Ivs. are longer and narrower 

 and are acutely pointed and pitted with white dots: 

 fl.-sts. 5 in. high, glandular-hairy and terminated by a 

 cluster of erect pink-tinted fls. ; the shade deeper toward 

 the base, fls. cylindrical in form with the petals never 

 reflexed. Feb., March. A garden hybrid. 



117. Eudoziana, Kellerer (S. Ferdindndi-Coburgi x 

 S. sdncta). An intermediate in character, but vigorous 

 like S. sancta. The Ivs. have the silvery appearance of 

 the former parent and the length and pointedness of 

 the latter: sts. tinged red and bearing a head of 2-3 

 deep orange-yellow fls. which are rather small. A gar- 

 den hybrid raised at Sofia, Bulgaria. 



118. apiculata, Engl. (S. Rochelidna x S. sdncta: S. 

 Frederici-Augusti, Hort., not Bias. S. luteo-purpurea, 

 Hort., not Lapeyr). Cespitose, forming a large dark 

 green mat, with subligneous, very densely Ivd. caudicles: 

 fl.-sts. 2-3H in. high, glandular-pilose: basal Ivs. linear- 

 oblong, acutely cuspidate, slightly carinate, thick, with 

 pitted margins; cauhne Ivs. subspatulate : infl. 5-9-fld., 

 the branches 1-2-fld.: fls. yellow; calyx with the tube 

 turbinate and densely glandular-pilose; lobes ovate- 

 oblong, apiculate and glandulose-ciliate ; petals obovate, 

 spreading, a little longer than the calvx-lobes. Dec.- 

 March. Said to be from the Pyrenees. B.M. 8048.

 44:186. Var. alba, Hort. Habit free, the fl.-sts. 3 in. 

 high, the fls. pure white or pale cream-colored and 

 borne profusely. G. 34:233. Gn. 73, p. 201. Var. 

 Malyi, Hort. (S. Mdlyi, Hort., not Schott, also spelled 

 Mayli and Molyi. S. luteo-purpurea var. Mdlyi, Hort.), 

 has deeper-colored fls. which are better shaped and
