Perennial, tufted, similar to the preceding species 

 hut densely strigose or hirsute. Leaves spatulate, 

 or oblanceolate, obtuse, the lower and basal ones 

 i'-ij' long; inflorescence of thyrsoid clusters; calyx 

 densely setose with yellowish hairs; corolla about 

 2" broad, its tube longer than the calyx, 2 or 3 

 times the length of the lobes; style filiform; nutlets 

 acutely margined, tuberculate on the back. 



In dry soil, western Nebraska (according to Web- 

 ber), Wyoming to Nevada and New Mexico. May- Aug. 



7. PNEUMARIA Hill, Veg. Syst. 7 : 40. pi 37- 1764. 



A perennial fleshy glabrous glaucous diffusely branched herb, with alternate entire 

 leaves, and small blue pinkish or white flowers in loose terminal leafy-bracted racemes. 

 Calyx-lobes triangular-ovate or lanceolate, somewhat enlarging in fruit. Corolla tubular- 

 campanulate, crested in the throat, 5-lobed, the lobes imbricated in the bud, slightly spread- 

 ing. Filaments slender, scarcely exserted. Ovary 4-divided; style slender. Nutlets erect, 

 fleshy, attached just above their bases to the somewhat elevated receptacle, smooth, shining, 

 acutish-margined, becoming utricle-like when mature. 



A monotypic genus of sea-beaches of the north 

 temperate zone.

Pale green, the branches spreading or ascend- 

 ing, 3'-i5' long. Leaves thick, ovate, obovate, or 

 oblong, i '-4' long, acute or obtuse at the apex, 

 narrowed at the base, the lower and basal ones 

 contracted into margined petioles, the uppermost 

 smaller ; flowers blue or nearly white, about 3" 

 long, all pedicelled ; pedicels very slender, 5"-i8" 

 long; calyx shorter than the corolla-tube; corolla 

 with a crest in the throat opposite each lobe; 

 nutlets about as long as the calyx-lobes when 

 mature. 



On sea-beaches, Long Island (?), Massachusetts to 

 Newfoundland and Greenland, Oregon to Alaska. 

 Also on the coasts of Europe and Asia. May-Sept. 



8. MERTENSIA Roth, Catal. Bot. i: 34. 1797. 



Perennial glabrous or pubescent herbs, with alternate sometimes punctate leaves, and 

 rather large blue purple or white flowers, in panicles, cymes, or racemes. Calyx-lobes lan- 

 ceolate or linear, little enlarged in fruit. Corolla tubular- funnel form or trumpet-shaped, 

 crested or unappendaged in the throat, its lobes obtuse, imbricated, little spreading. Stamens 

 inserted on the tube of the corolla, included, or scarcely exserted ; filaments flattened, or 

 filiform; anthers oblong or linear, obtuse. Ovary 4-divided; style filiform. Nutlets erect, 

 coriaceous, wrinkled when mature, attached above their bases to the convex or nearly flat 

 receptacle. [In honor of Prof. C. F. Mertens, a German botanist.] 



About 40 species, natives of the northern hemisphere. Besides the following, many occur 

 in the western part of North America. The species are called Smooth Lungwort. Type species : 

 Mertensia pulmonarioides Roth. 



Corolla trumpet-shaped, not crested in the throat, the limb barely s-lobed. i. M. virginica. 



Corolla funnelform-campanulate, crested in the throat, the limb manifestly 5-lobed. 



Stem-leaves ovate or ovate-lanceolate, acuminate. 2. M. paniculata. 



Stem-leaves oblong or lanceolate, obtuse or acute. 3. M. lanceolata.
