A pretty little plant, from six to eight inches high, with hairy leaves cut into narrow divisions and passing into pinkish-lilac bracts towards the top of the stalk, which are mixed with pink and white flowers, each about an inch long, so that the effect of the whole is a spike of pink and white. The lower lip of the corolla is white and the upper lip is pink, with a furry tip. This grows in fields. 0. attenuates, common in fields in the Northwest, is a slender inconspicuous kind, about nine inches tall, with soft, thin, dull green leaves, most of them not lobed, and pale green bracts, often tipped with white. The corollas are dull white, the lower lip dotted with purple or yellow, and the whole effect of the cluster is feathery, very slender, and pale in color. There are a good many kinds of Pedicularis, usually with finely-cut leaves and spikes of queerly-shaped flowers, usually yellow, sometimes red or white; the corolla conspicuously two-lipped, the upper lip hood-like, long and narrow, the lower lip three-lobed; the stamens four, two of them short, in the upper lip; the capsule flattened or compressed, beaked, splitting open, and containing many seeds. These plants are supposed to cause lice in sheep that feed on them, so they have the ugly name of Louse-wort, both in English and Latin.
