SAXIFRAGA. 



narrower leaves, and somewhat larger 



flowers. The rock-garden, borders, 



and naturalization in open rocky 

 places, in any soil. Division. 



Saxifraga crassifolia (Thick-leaved S.) 

 Megasea crassifolia. A stout large- 

 leaved perennial, very closely allied 

 to cordifolia. Flowers, in spring ; 

 red, in a thyrsoid panicle, on a thick 

 stalk about 9 in. high ; petals elliptic- 

 oblong, erect; calyx bell-shaped, half 

 as long as the petals, 5-parted to about 

 the middle, somewhat wrinkled on 

 the outside, green. Leaves, alternate, 

 spreading, about 9 in. long, flat, 

 leathery, obovate or oblong, sub-retuse, 

 very smooth, veined; stalks half the 

 length of the leaves, roundish, chan- 

 nelled, smooth, with an ovate mem- 

 branous stipule at the base. Native 



of Siberia. Similar uses to those 



given for S. cordifolia, to which this 

 is on the whole superior. Around Paris 

 I have seen it used with good effect in 

 beds in the spring-garden. It will 

 prove much finer in warm and shel- 

 tered positions, for, though very hardy, 

 the blooms are far better developed in 

 sunny sheltered spots. Division and 



Saxifraga Cymbalaria (Ivy ) A 

 distinct abundantly - blooming little 

 annual species, with shining leaves 

 somewhat like those of the Wall 

 Linaria ; 3 in. to 1 ft. high. Flowers, 

 continuously from early spring to au- 

 tumn ; bright yellow, in dense masses, 

 on numerous, weak, sprawling stems ; 

 petals obovate, much longer than the 

 calyx ; sepals oblong. Leaves, kidney- 

 shaped, with crenate lobes, stalked. 



The Caucasus. The rock - garden 



or borders, in ordinary soil. It is 

 easily increased by seed, and often 

 sows itself abundantly. 



Saxifraga diapensioides (Diapensia 

 S.} A dense-growing and diminutive 

 kind, and one of the most ornamental. 

 Flowers, in early summer, white, bell- 



shaped, 3 to 5 in a terminal head "U 

 leafy stems, rarely exceeding 2 in. 

 high, densely covered with viscid 

 hairs ; petals oblong, narrowed at the 

 base, with a 5-nerved limb. Leaves, 

 grey, 3- edged, linear, obtuse, with 

 cartilaginous margins, ciliated at the 

 base and with one or two perforated 

 dots at the points, packed into dense 

 cylindrical rosettes. Alps of Switzer- 

 land, Dauphiny, and the Pyrenees. 

 The treatment and positions re- 

 commended for S. arelioides will suit 

 this perfectly. It may also be freely 

 grown in pans. Seed and division. 



Saxifraga Geum (Kidney S. ) Very 

 like the London Pride, and differing 

 chiefly in its leaves. Flowers, in early 

 summer; pink, with darker spots, 

 about in. across, in a loose, slender 

 panicle. Leaves, roundish, heart-shaped 

 at the base, with scattered hairs on 

 both sides, on long stalks, which are 

 usually very hairy, and less flattened 

 than those of S. umbrosa. There are 

 several varieties of this. S. hirsuta 

 is very closely allied to it, if anything 

 more than a variety, differing chiefly 

 by its leaves being longer than broad, 

 less heart-shaped, and more hairy. 

 South - western Ireland, and other 



parts of Europe. Borders, edgings, 



and the rougher parts of the rock- 

 garden, in ordinary soil ; also wild in 

 woods and copses. Division. 



Saxifraga granulata (Meadow S.) 

 A rather common native species, dis- 

 tinct in aspect from the alpine kinds, 

 with several small scaly bulbs in a 

 crown at the root ; 6 to 12 in. high. 

 Flowers, in spring and early summer ; 

 white, about f in. across ; 3 to 6 

 together in a branched terminal 

 panicle ; petals obovate, much longer 

 than the calyx, marked with 3- 

 branched veins. Leaves, somewhat 

 fleshy, kidney shaped, crenate orlobed, 

 thickly clothed with shaggy glandular 

 hairs; root-leaves on long stalks ;
