From the last species this one differs in being more hairy (hence hirsuia), and in the sharply-toothed leaves, rounded or blunt below. It also resembles S. Genm. The leaves are oval, heart-shaped, blunt, sharply-toothed, very hairy, leathery, longer than broad.
The leaf-stalks are linear, half-round in section, with raised edges, tapering upwards. The flowers are rose-colour, in panicle-like racemes. The plant is 6-12 in. high, flowering in June and Juby, and is a herbaceous perennial.
The habitat of this species is stony mountain rills, wet places on mountains. The plant has the rosette or cushion habit. The stems are prostrate below, tufted, leafy, much-branched, bright-green. The leaves are linear, oblong, the lower bent-back, alternate, entire, or with stiff teeth, crowded below, blunt-pointed, scattered on the flowering stems, fringed with hairs, flat above, convex below. The flowers are in a leafy panicle, yellow, with red spots. The sepals are blunt, erect, united below the ovary, the teeth inversely conical. The petals are narrow, distant, not contiguous, inversely ovate to spoon-shaped. The stalks are glandular. The ovary is depressed, orange. The capsule is erect to spreading, with awl-like beaks. The plant is 4-6 in. high, flower-* ing from June to September, and is a herbaceous perennial.
The habitat of this plant is alpine wet rocks and streams on the coldest parts of mountains. The plant has the rosette or cushion habit. The stems are prostrate or ascending, tufted, slender, rooting, succulent, glandular, hairy. The leaves are radical, kidney-shaped, palmately-lobed, the lobes entire, rounded, 5-lobed, stalked. The leafstalk is slender, as long as the stems. The upper leaves are lance-shaped, entire. The flowers are white, few, stalked, erect. The bracts are leafy, opposite, usually entire. The calyx is half-inferior, with acute lobes as long as the tube, hemispherical. The petals are small, distant, inversely ovate to oblong. The capsule has short, spreading beaks. The plant is 1-4 in. high, flowering in Juiy and August, and is a herbaceous perennial.
The habitat of this plant is schistose rocks. The plant has the rosette habit. The rootstock has scaly buds at the top. The plant is glandular, hairy, leafy. The stems are erect, simple, 1-flowered. The radical leaves are stalked, kidney-shaped, the lobes palmate, scalloped-lobed, red-tinged. The stem-leaves are nearly stalkless, more or less 3-fid, with scarlet buds in the axils, deeply lobed. The flowers are replaced by reddish bulbs, or drooping, bell-shaped, white, and are rarely found in Britain. The calyx-tube is very short, inferior, the lobes erect, blunt. The petals are large, inversely ovate. The plant is 2-4 in. high, flowering in July and August, and is a herbaceous perennial.
