SAXIFRAGA 



81. Friderici-A&gusti, Bias., also spelled Frederici- 

 Augusti and Federici-Augusti (S. porophylla, Boiss., not 

 Bertol. S. semperinvum, Koch. S. thessdlica, Schott.). 

 Cespitose, 2-6 in. high with short densely foliate caudi- 

 cles: sts. erect, densely glandular: basal Ivs. forming a 

 flattened rosette, linear-lanceolate, acute or acutish, 

 glabrous, flat, entire, often ciliate at the base, remotely 



Eitted near the margin; cauline Ivs. spatulate, glandu- 

 ir: infl. a spike-like raceme, dark purple; pedicels all 

 about equal and shorter than the bracts: fls. violet- 

 purple; calyx glandular, the lobes ovate, obtuse; petals 

 cuneate-spatulate, scarcely longer than the calyx-lobes. 

 April. Dalmatia, Serbia, Greece, and N. E. Asia Minor. 

 G. 35:761. This species has been treated as S. media 

 var. Friderici-Augusti, Engl., but differs from that 

 species in the narrower Ivs. and more spicate raceme. 

 It has also been referred to S. porophylla, Bertol., as a 

 synonym: the latter is said to have Ungulate basal Ivs. 

 with obtuse apex, and flesh-colored petals. The dis- 

 tinctions between S. Friderici-Augusti and S. poro- 

 phylla seem to be very unsatisfacory. Much of the 

 material cultivated as S. Frederici-Augusti is really S. 

 apiculata. 



82. aretioides, Lapeyr. Cespitose, about 2 in. high, 

 with woody, densely imbricate-foliose caudicles: sts. 

 short and leafy, glandular-hirsute: lower Ivs. sulcate, 

 weakly keeled, leathery and stiff, both sides gray-green 

 but violet at the base of the under surface, linear-lingu- 

 late, apex rather obtuse, margin narrowly cartilaginous, 

 the lower portion ciliate and near the margin are 7-9 pits 

 noticeable with age; cauline Ivs. linear-spatulate, glan- 

 dular-hirsute and cartilaginous except the apical por- 

 tion: infl. terminal, 1-3-fld., rarely cymose, 3-5-fld. ; the 

 pedicels and calyx glandular: fls. golden yellow, calyx- 

 lobes ovate and acutish; petals broad-obovate, 5-7- 

 neryed, more than twice as long as the calyx-lobes. 

 April- July. Mountains of Eu. B.M. 5849.-^-Should be 

 planted on a shady ledge where it will obtain plenty of 

 moisture. Little known in Amer. Var. primulina, 

 Hort., grows about 1^ in. high; the peduncles are paler 

 green than the type; the fls. are true primrose-yellow 

 and the petals are usually well rounded and fairly well 

 imbricated. 



83. Ferdinandi-CSburgi, Kell. & Sunderm. Cespitose, 

 about 2 in. high, with columnar foliose branched caudi- 

 cles: sts. with 9-12 Ivs., glandular-hairy as is the calyx 

 and tinted red-brown: lower Ivs. somewhat glaucous, up 

 to y$&. long, little narrowed toward the top, margin 

 fine-hairy below, apex thickened and incurved-pointed ; 

 cauline Ivs. 9-12 in number: infl. close heads of 4-5 

 (5-6) large, rich yellow fls. : petals rsin. long, J^in. wide, 

 strongly narrowed toward the base. March, April. 

 Macedonia. 



84. scardica, Griseb. (S. scarellica, J. Wood). Cespi- 

 tose, 3-4 in. high, with woody, very densely foliate 

 caudicles: sts. ascending and glandular-pilose: basal 

 Ivs. leathery, stiff, light gray-green, pale violet toward 

 the base, oblong acute, spreading, upper surface con- 

 cave, lower convex-carinate, lower margin indistinctly 

 serrulate or ciliate, upper cartilaginous, entire, when 

 old there are 9-15 pits near the margin; cauline Ivs. few, 

 lanceolate, acute, glandular-hirsute except the apical 

 portion, cartilaginous and glandular-hirsute: infl. 

 corymbose, 3-11-fld.: fls. white, ivory-white, or pale 

 rose-red; calyx-lobes ovate, acutish; petals obovate- 

 cuneate, 5-nerved, more than twice the length of the 

 calyx-lobes. June, July. Orient. B.M. 8243. Gn. 65, 

 p. 323; 69, p. 231. S. E. Eu. Readily distinguished 

 from S. Rocheliana by its keeled and more pointed Ivs. 

 The species itself is hard to grow and consequently is 

 rare in cult. The plant grown as S. scardica vera is the 

 true S. scardica, Griseb. G. 34:199. Var. obtftsa, 

 Sprague, differs from the type in having subacute to 

 obtuse lower Ivs. with fewer pits, fl.-sts. 1-3-fld. and 

 green, and the calyx-lobes obtuse and less pubescent. 



March. Macedonia. B.M. 8058 (as S. scardica}. G. 

 32:529. 



85. Rocheliana, Sternb., also incorrectly spelled 

 Rochelliana. Very densely cespitose-cushioned, form- 

 ing mats 8-12 in. diam., 2-3 in. high, with more or less 

 elongated, densely imbricated, foliose, often columnar 

 caudicles: lower Ivs. stiff, shiny light gray-green above, 

 violet below, densely aggregated, horizontally spread- 

 ing, spatulate, obtuse, very smooth, flat above, rather 

 convex below the base, ciliate, 7-9 pits near the margin 

 noticeable when old; cauline Ivs. few, obovate-spatu- 

 late, cartilaginous and glandular-pilose except the 

 apical portion: infl. corymbose-paniculate, 3-9-fld., 

 borne on an erect purple-red glandular-pilose fl.-st.; 

 pedicels erect, these and calyx glandulose and pale green : 

 fls. white; calyx-lobes ovate, obtuse, erect; petals obo- 

 vate, clawed-attenuate, 7-nerved, thrice the length of 

 the calyx-lobes. April- July. E. andS. E. Eu. Flowers 

 freely. Var. coriophylla, Engl. (S. coriophylla, Griseb., 

 also spelled coryophylla) . The lower Ivs. smaller, less 

 horizontally spreading, oblong, obtuse, fewer pitted: 

 fls. ivory-white. Bosnia and N. Albania. 



86. marginata, Sternb. Cespitose, about 3 in. high, 

 with caudicles which are subnaked below or short- 

 columnar, woody and leafy: lower Ivs. obovate-cuneate, 

 obtuse, the base ciliate, the upper margin cartilaginous; 

 cauline Ivs. cartilaginous and glandular-pilose excepting 

 the apical portion: infl. corymbose, 5-7-fld., borne on 

 erect fl.-sts., these as well as the pedicels and calyx 

 being black-glandular-pilose: fls. white; calyx-lobes 

 ovate-oblong, obtuse; petals obovate, attenuate at 

 base, 5-7-nerved, 3 times the length of the calyx-lobes. 

 March-June. S. Italy. B.M. 6702. Gn. 77, p. 206; 79, 

 p. 294. G.L. 18:117. Suitable for sunny ledges and 

 rocky crevices, but requires lime and good drainage. 

 Some of the material cult, under this name may be S. 

 Boryi. 



87. B6ryi, Boiss. & Heldr. (S. marginata, Bor. & 

 Ch., not Sternb.). Cespitose-cushioned, about 1^ in. 

 high, with densely imbricate-foliose caudicles which 

 are elongated and columnar : lower Ivs. oblong-spatulate, 

 obtuse, glabrous, erect-spreading, subcoriaceous, flat 

 above and subcarinate below, margins ciliate at base 

 or others entire, remotely pitted near the margin; 

 cauline Ivs. few, minute and glandulose: infl. corym- 

 bose, 3-5-fld., borne on erect glandular fl.-sts.: fls. 

 white; calyx glandular, the lobes triangular-ovate, 

 acute; petals elliptic-spatulate, twice the length of the 

 calyx-lobes. April-July. S. E. Eu. Thrives in a sunny 

 location. Closely allied to S. marginata but differs in 

 having smaller Ivs., acute calyx-lobes and shorter and 

 narrower petals. 



88. lilacina, Duthie. Cespitose, J^-l in. high, with 

 numerous very densely foliose, columnar caudicles: Ivs. 

 rosulate, oblong, obtuse, recurved and thickened toward 

 the apex, sparsely ciliate at the base, margin cartila-

 spatulate, obtuse, glandular, half -clasping at base : infl. 

 1-fld., borne on glandular-pubescent fl.-sts. which are 

 lilac: fls. about J^in. diam., pale or rosy lilac with a 

 purple center; calyx K m - long, glandular-pubescent, 

 the lobes ovate-oblong, obtuse; petals J^in. long, 

 obovate-rotund, cuneate at the base, the margins undu- 

 late. March, April. W.Himalayas. G.C. III. 35:290. 

 Gn. 65, p. 250. The plant is very dwarf, and is grayish 

 green in color, though the If .-tips are dark green. 



89. squarrSsa, Sieber. Very densely cespitose, about 

 3 in. high, with woody, subcylindrical caudicles which 

 are very densely imbricate-leafy : Ivs. of the caudicles 

 dark green, imbricated, erect, becoming curved-spread- 

 ing at the apex, linear-lanceolate, obtuse, submucronu- 

 late, very narrowly cartilaginous margined, at the base 

 fimbriate, the back convex and obtusely carinate above, 

 marked with 7 pits, crustate with lime when young;
