 British Flora, ed. 4. vol. i. p. 237.— Lindley, Synopsis, p. 190. 



Root tapering, stout, branched. Stem three to five inches high, 

 erect, angular, nearly smooth, as is the rest of the plant, much branched 

 and leafy at the base, the branches slender, mostly longer than the 

 stem, and spreading around on the surface of the grass or ground. 

 Leaves numerous, the radical ones surrounding the base, ovate oblong, 

 entire, cut, or pinnatifid, sub-membranous, the upper ones pinnated, 

 with ovate or oblong mostly cut and serrated li)bes, on a slender round 

 common footstalk, naked at the base. Injiorescence axillary solitary 

 flowers in the axis of the leaves, often from almost the base of the 

 stem and on the branches towards the extremity. Floivers a delicate 

 pink, paler than the last species. Calyx sessile, becoming elevated on 

 a short stalk, oblong, smooth, with prominent ribs, the limb unequally 

 divided into five teeth, unequally crenated, mostly leafy, downy on 

 the margin. Corolla with a narrow tube, inflated upwards, as long 

 again as the calyx, two lipped, the upper lip compressed, elongated, 

 somewhat curved, concave, obtusely rounded at the extremity, and with 

 an angular awl-shaped tooth near the extremity on each side, the 

 lower lip of three roundish spreading nearly equal lobes. Stamens 

 with smooth slender thread-shaped filaments inserted into the base of 

 the corolla, curved beneath the upper lip, the anthers large, ovale, 

 yellow, two celled, pointed at the base. Style long, slender, thread- 

 shaped, protruded beyond the upper Up. Capsule ovate, obliquely 

 pointed. 



Habitat. — Moist pastures and heathy places ; common. 

 Perennial ; flowering in June and July. 



The flowers of this species are larger than the last, and are some- 

 times found of a salver-shape, with a regular six-cleft limb and six 

 stamens, four long, and two short. A white flowered variety is also 

 sometimes met with in the Western Highlands and other parts of Scot- 

 land. The calyx segments are often remarkably expanded into pin- 

 natifid leafy lobes, of the same structure and appearance as the leaves.
