 Oreocarya f 11 l-joca nesceiis Greene , Pittonia, i: 58. 1887. 



Perennial, tufted, similar to the preceding species 

 but deusely strigose or hirsute. Leaves spatulate, 

 or oblanceolatc, obtuse, the lower and basal ones 

 I'-i^' 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; nut- 

 lets 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. pL 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 iu 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-margined, 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, 

 \'-\' 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, 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 

 Newftmndland and Greenland, Oregon to .\laska. 

 Also on the coasts of Europe and .\sia. 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 uuappendaged 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, wrinkleil when mature, attached above their bases to the convex or nearly flat re- 

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



.\b(iut 14 species, natives of the northern hemisphere. Besides the following, 3 others occur 

 in the western part of North .\merica. The ■species are called Smooth Lungwort. 

 Corolla trumpet-shaped, not crested in the throat, the limb barely 5-lobed. i. M. Virginica. 



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



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