P. farinosa: leaves obovate-lanceolate, glabrous above, and usually covered underneath with white meal, which is also observable on the peduncles and calyx; peduncles much longer than the leaves, supporting a compact umbel of small, pale-lilac flowers, having a yellow eye; the corolla lobes narrow, and deeply notched. - Mountain pastures in northern England and Scotland.

P. scotica, which has broader leaves, and shorter and broader lobes to the corolla, is sometimes regarded as a variety or more northern form of P. farinosa. [See also p. 59.]
