V.' 



V-i l / 2 ' long; inflorescence of thyrsoid clusters; 

 calyx densely setose with yellowish hairs; corolla 

 about 1" broad, its tube longer than the calyx, 2 or 

 3 times the length of the lobes; style filiform; nut-

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

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

 acutish-rnargined, becoming utricle-like when mature. 



A monotypic genus of sea-beaches of the north 

 temperate zone.

Pale green, the branches spreading or ascending, 

 3 / -i5 / long. Leaves thick, ovate, obovate, or oblong, 

 1/-4/ long, acute or obtuse at the apex, narrowed at 

 the base, the lower and basal ones contracted into 

 margined petioles, the uppermost smaller; flow- 

 ers blue or nearly white, about 3" long, all pedi- 

 celled; pedicels very slender, $"-\%" 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, L,ong 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-funnelform 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 fili- 

 form; 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 re- 

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



About 14 species, natives of the northern hemisphere. Besides the following, 3 others occur 

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

 Corolla trumpet-shaped, not crested in the throat, the limb barely 5-lobed. 1. 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. lanceolala.
