Perennial. June. 



The herbage consists of several leafy, evergreen tufts. Leaves nu- 

 merous, spreading, rigid, almost orbicular, or rather kidney- 

 shaped, being usually broader than long j heart-shaped at the 

 base ) besprinkled on both sides with rigid bristly hairs, which 

 however are nearly wanting in both the varieties ; the under 

 surface reticulated or speckled with purple ; the margin regu- 

 larly and rather sharply crenate, scarcely cartilaginous, the ter- 

 minal or central tooth shorter, and often broader than the rest. 

 Footstalks twice, sometimes four times, the length of the leaves, 

 narrow, linear, channelled, densely hairy. Flower-stalks soli- 

 tary, hairy, about a span high, panicled in the upper half, with 

 numerous, alternate, corymbose, hairy, viscid branches. Brac- 

 teas small, linear-spatulate, spreading, hairy, solitary under each 

 branch of the panicle, permanent. Fl. small. Segments of the 

 cahjx ovate, obtuse, reddish, hairy, obscurely 3-ribbed, strongly 

 reflexed as soon as the flower is expanded, permanent. Petals 

 n arrow- obovate, obtuse, cream-coloured, purplish at the base, 

 with a dull yellow stain towards the middle of the disk. Caps. 

 ovate, reddish, tipped with the short, brownish, more or less 

 divaricated, styles. 



I have long cultivated this species, sent by Mr. Mackay, and find 

 it very little variable. The petals have only a solitary spot of 

 dull yellow on their disk, and the leaves are constantly purple at 

 the back, most hairy on the upper side. Magnol's elegant plate, 

 indicated above, answers perfectly to our plants but his descrip- 

 tion, p. 87, agrees better with -S. hirsuta, especially as he there 

 describes the leaves nearly round, and the petals with bloody 

 spots. Mr. Don's and my variety y has 3 or 4 crimson spots 

 on each petal, besides a bright yellow stain, and the leaves are 

 nearly, not quite, smooth. If they were more hairy, I should 

 have no doubt of Morison's/. 12 belonging to this variety j nor 

 indeed do I know what else it can be. Lapeyrouse's t. 24 is 

 perhaps most like this y. 



2. S. hirsuta. Hairy Oval-leaved Saxifrage. 



Leaves oval, with sharp cartilaginous notches: slightly hairy; 

 heart-shaped at the base. Footstalks linear, much longer
