almost twice as long as the calyx-lobes: fr. globose. June, 

 July. Alpine and boreal parts of Eu. and Asia, in N. 

 Amer. from Greenland and Lab. to Sask., locally south 

 to Nova Scotia, New Bruns., mountains of N. Vt., and 

 Lake Superior. J.H. III. 69:135. A very variable 

 alpine plant, much tufted and forming small dense 

 rosettes. S. Pfirtae, Stein, from Italy has white fls. and 

 is apparently only a minor variation of S. Aizoon. Var. 

 ambigua, Hort,, is offered in the trade. Var. atropur- 

 pftrea, Hort., is said to have slender branching sts. and 

 rose-purple fls. Var. balcana, Hort., also spelled balkdna 

 (S. balcana, Hort.), is a form with close rosettes of 

 medium size and rather flat 'white fls. with larger red 

 spots than usual (fls. reported as sometimes pale pink). 

 Balkan Mts. Var. baldensis, Fairer, with ash-gray Ivs., 

 which are short, thick and markedly dentate; their 

 apex rounded: the young shoots glossy, blood-crimson: 

 fls. whitish. N. Italy. Var. brevifdlia, Hort., with white 

 fls. is offered in the trade. Var. bulgarica, Hort., has 

 rosy spotted fls. Var. californica, Hort. (S. californica, 

 Hort.), with white fls. must not be confused with S. 

 californica, Greene (Micrdnthes californica, Small), a 

 species of Section Boraphila, closely related to S. 

 virginiensis which is probably not in cult. Var. Church- 

 illii, Hort., with pointed gray Ivs. in stiff rosettes. 

 Var. cultrata, Hort., is offered in the trade. Var. dftbia, 

 Hort., is offered^. Var. erecta, Hort., is offered in the 

 trade. Var. flavescens, Hort., is a free-growing decora- 

 tive form with clear lemon-yellow fls. produced in good 

 spikes. Not to be confused with S. flavescens, Hort. (S. 

 media x S. aretioides), which is apparently scarce in 

 cult. Var. intacta, Engl. (S. intdcta, Willd.), has beau- 

 tiful white, unspotted fls. S. intdcta major is the cultural 

 name of a larger form, about 6 in. high. S. intdcta 

 minor is the cultural name of a dwarf form. Var. 

 lagaveana, Hort., also known as La Gravedna and La Ga 

 Dauphane, is a miniature plant with tiny silvery rosettes 

 and ruddy sts. 6 in. high, bearing 4-6 fls. on each st. : 

 fls. creamy white,, thick and wax- 

 like; the buds globular and pink- 

 tinted. Var. Ifttea, Hort., has the Ivs. 

 longer, the rosettes more open, and 

 the fls. deeper yellow than those of 

 var. flavescens; fls. at first primrose- 

 yellow changing to creamy yellow. 

 Var. Malyi, Hort. (S. Mdlyi, Schott, 

 not Hort.), is one of the tallest 

 forms, with good -sized rosettes. 

 Var. major, Koch (S. Aizoon forma 

 robusta, Engl.), has oblong-linear 

 Ivs. which are not much broader at 

 the apex. Var. minima, Hort., is a 

 diminutive plant that clings tightly 

 to the rock faces and looks almost 

 like a gray moss: fls. white. Var. 

 minor, Koch, has oblong - obovate 

 Ivs. shorter than the type. Var. 

 notata, Hort. (S. notdta, Schott), has 

 small silver-margined Ivs. and 

 white fls. Var. paraddxa, Hort., 

 is a form with long bluish Ivs., 

 their margins with silvery ser- 

 ratures: fls. white. Engadine. 

 Gn. 74, p. 463. See 

 S. paradoxa in suppl. 

 list. Var. pectinata, 

 Hort. (S. pectinata, 

 Schott, Nym. & 

 Kotschy), has nar- 

 row Ivs. with blunt 

 teeth and conspicu- 

 ous silvery margins 

 forming small ro- 

 settes: the fls. are 

 small, of a nice white 

 3562. sazrfraga Aizoon. ( x K 2 ) and spotted with red. 



SAXIFRAGA 



Var. recta, Ser., in part (S. recta, Lapeyr, in part. S. 

 Aizobn forma grdcilis, Engl. S. carintfnaca, Schott, Nym. 

 & Kotschy), has Ivs. which are spatulate-linear, slightly 

 dilated toward the apex, narrowly and also deeply ser- 

 rate: the sts. laxly paniculate from the middle and 

 above; the branches 1-3-fld.; fls. white. Var. rdsea, 

 Hort., is similar to the type, but has bright pink fls. 

 Var. rosularis, Hort. (S. rosuldris, Schleich.), has finely 

 incurved rosettes and large sprays of white fls. Var. 

 Stabiana, Hort. (S. Stabiana, Ten.), has large rosettes 

 and sprays of creamy white fls. Not very distinct from 

 the type. Var. Sturmiana, Hort. (S. Sturmidna, Schott, 

 Nym. & Kotschy), is a good-sized form with flattish 

 rosettes, probably referable to the type-form. 



74. Zelebori, Schott. Sts. densely and longly glandu- 

 lar-pilose toward the base, decreasingly so toward the 

 apex: Ivs. of the glaucous rosette, which is 1 1/2 in. diam., 

 almost linear, acute, very minutely serrate, the serra- 

 tures inverted-acute and contiguous (the lowest less 

 so); cauline Ivs. shorter, oblanceolate, acute, glabrous, 

 above the middle sharply serrate (serratures rather 

 remote), apex appressed serrate-crenate : fls. white, not 

 dotted; calyx glabrous, the lobes lanceolate-elliptic, 

 obtuse; petals oblong-elliptic, not clawed, obtuse, apex 

 rounded. Serbia. Plants under this name are offered 

 in English trade-lists, but the species is not included in 

 any of the recent treatments of Saxifraga. The above 

 description is taken from Schott's original. Whether 

 the plant offered is the same is undetermined. Proba- 

 bly a variation of S. Aizoon. 



75. cartilaginea, Willd. (S. Kolenatidna, Regel). 

 Six to 9 in. high: st. sparingly glandulose, few-lvd.: Ivs. 

 rosulate, oblong or obovate-oblong, acute or acuminate; 

 the margin cartilaginous toward the base, serrate, ser- 

 ratures antrorsely subacuminate, toward the apex sub- 

 crenate, crenatures truncate: infl. a scape, racemose or 

 paniculate above, the branches 1-5-fld. : fls. white, rose, 

 or purple; calyx-lobes ovate-triangular, rather acute; 

 petals obovate, 2-3 times longer than the calyx-lobes. 

 June-Aug. Caucausus region and Asia Minor. S. 

 Kolenatiana has been kept distinct by some but seems 

 to differ only in the slightly more acute serratuies of the 

 Ivs. In gardens it is more common under this name. A 

 somewhat larger form is known as S. Kolenatidna 

 major, Hort. 



76. Cotyledon, Linn. Tufted, 6-24 in. high: st, erect: 

 Ivs. thick and fleshy, basal Ungulate or obovate-lingu- 

 late, short-apiculate, the base softly fimbriate; margin 

 serrate, serratures cartilaginous, at their apex antrorsely 

 acuminate; cauline Ivs. lingulate-lanceolate, the lower 

 part glandular-ciliate, the upper serrulate; bracts linear, 

 acute and glandular: infl. a scape, paniculate from the 

 base, the panicle composite, pyramidal, glandular-pilose 

 all over, the branches paniculate from their middle, 

 5-15-fld. : fls. white, occasionally tinged rose; calyx-lobes 

 longer than the glandulose tube, oblong-acute; petals 

 obovate-cuneate, 3-5-nerved, midnerve mostly bifid, 

 2-3 times longer than the calyx-lobes. May-July. 

 Mountains of Eu. G. 11:209; 34:781; 35:541. G.W. 

 12, p. 471. Easy to prop, as it makes a large number of 

 side^ shoots which root quickly when potted. Var. 

 icelandica, Maxwell (S. iceldndica, Hort.), is the largest 

 form of the species and produces numerous offsets. The 

 rosettes are very large and flat and the ligulate Ivs. are 

 usually bronzed and leathery. G. 35:707. Var. pyram- 

 idalis, Ser. (S. pyramiddlis, Lapeyr, not Ten. S. nepalen- 

 sis, Hort.), is a very robust form from 2-4 ft, high 

 when in fl. The rosettes are large and glaucous and 

 the fls. very numerous in a large pyramidal panicle, 

 white, speckled with crimson. May, June. G.C. III. 

 53:389. G. 35:163. Gn. 61, p. 393; 74, p. 266; 78, p. 

 349. Var. pyrenaica, Hort,, has more pointed Ivs. and 

 shorter plumes of white fls. Pyrenees. 



77. mutata, Linn. Six to 12 in. high: rhizome' thick, 

 horizontal or oblique: sts. ascending, foliose: basal Ivs.
