FIG. 434. SAXIFRAGA ROCHELIANA CORIOPHYLLA. 



8. R. coriophylla (Coris-leaved).* I., lower ones smaller and

 margins. See Fig. 434.

 late. h. 1ft. Austria, Ac., 1596. (B. M. 424 ; S. F. G. 377.) The 

 variety repanda is larger and more robust, and has broader 

 leaves.

 two-flowered. 1., basal oneTlong-petiolate, small, with s"- 1 -"- 

 hairy margins, reniform or nearly round, five to nine 

 cauline o: 



8. sanota (holy).* fl. yellow, in a short, dense spike; petals 

 spathulate-oblong. Summer. I. rigid; lower ones imbricated, 

 spreading, lanceolate, acuminate, rigidly mucronate, ciliate, den- 

 ticulate on the margins, keeled : cauline ones lanceolate, murro-

Saxifraga continued. 



fl. white, two of the inner petals having a yellow spot, and the 

 central one two scarlet spots, at the base ; two outer petals large, 

 flaccid. June and July. 1. orbicularly cordate, crenate-lobed, 

 pilose, red beneath. Stolons or runners creeping. A. 9in. China 

 and Japan, 1815. Half-hardy. (B. M. 92.) 



S. 8. minor (smaller). A smaller-growing form. (B. H. vii. 13, 

 under name of 5. s. minor semperjlorens.) 



S. s. tricolor (three-coloured). This differs from the type in 

 having the foliage beautifully blotched with creamy-white and 

 red. It is well adapted for growing in vases and hanging baskets. 

 See Fig. 435. 



S. Schmidtii (Schmidt's), fl. purplish, paniculate, similar to 

 those of S. craggifolia. Early summer. I. ovate, rounded at both 

 ends, or attenuated into the petioles, denticulate-ciliated.

 twice as long as the calyx segments ; panicle corymbose, three to 

 five-flowered. June. I., lower ones spathulate, ciliated, entire, 

 obtuse at apex, rarely three-toothed, three-nerved ; cauline ones 

 linear. Stem slender, erect. Algiers.

 S. ccesia. Early summer. I. linear-elliptic, rather retuse, stiff, 

 squarrosely imbricated, permanent, mealy when young. Stem 

 pubescent below, usually three-flowered ; branches diffuse, flaccid.

 entire. Europe (BritainX &c. Plant glabrous or sparsely hairy, 

 stemless. (F. D. 23; Sy. En. B. 54i) 



S. Sternbergil (Steinberg's). A form of S. hypnoidet. 



S. Stracheyi (General Strachey's).* /. pink, Jin. to lin. in 

 diameter ; petals obovate-spathulate or orbicular ; panicle much- 

 branched, drooping, glandular pubescent. March. I. closely 

 sheathing at base, with orbicular stipular sheaths, obovate or 

 obovate-cuneate, 3in. to 6in. long, narrowed into the short, stout 

 petiole, or cordate at base ; margins irregularly toothed, ciliated. 

 h. 4in. to Sin. Western Himalayas, 1851. (B. M. 6967.) S. S. alba 

 (R. G. 1228) differs from the type in its less spreading, white

 rtrite, with a distinct claw ; corymbs dense. 



March. L 9in. to 12in. long, 4in. to 5in. broad. 1872. A plant of 

 garden origin. This resembles the type, but differs in its longer 

 leave

es, and the more distinct claw to its petals.

 slightly branched raceme ; petals sub-rotundate, longer than the 

 sepals. April. I. obovate, deeply crenate-serrated, hairy on 

 both sides, but especially beneath, h. bin. to Sin. India. 

 (B. R. 1846, 33.) 



S. tenella (slender), fl. white ; petals obovate-oblong, twice as 

 long as the calyx segments ; panicle few-flowered. June and 

 July. I. linear -subulate, cuspidate - aristate, sparsely setulose- 

 ciliated on the margins or glabrous, glandularly ciliated towards 

 the base. Stems erect, slender, glabrous, h. bin. Alps, 1819.
