Pulmonaria (Latin, lung; the herb having been considered a remedy for diseases of the lungs). Bor- aginaceae. Lungwort. Perennial herbs with a creeping rootstock, used in flower-gardens and hardy borders.

Leaves radical, often broad, cauline few and alternate: fls. in terminal cymes, rather large, blue or purple; calyx tubular-campanulate, 5-toothed or cleft to the middle only; corolla-tube straight, naked or pilose, limbs spreading, 5-lobed; stamens included in the tube: nuts smooth.—About 8-10 species in Eu. and 1 species said to extend into N. Asia. Mertensia, an allied genus, has a short open more deeply-cleft calyx, exserted, stamens, and slightly fleshy nuts.

Pulmonarias are of easy cultivation, preferring light soil, not very dry, in open or partially shaded positions. They are readily propagated by division. Divide the clumps every two or three years.

P. Alba, Hort. Saul., is presumably Mertensia sibirica var. alba.— P. avernensis, Hort., with purple-blue fls.and compact growth, and its var. alba, Hort., with pure white fls., and good green lf., flowering in March, are listed.-P. sibirica. See Mertensia sibirica.—P. virginica. See Mertensia virginica. F. W. Barclay. F. Tracy Hubbard.
