 Acad. x. 52 ; Benth. & Hook. 1. c. (Stamens, in all but one of our species, pro- 

 truding from the throat, but shorter than the limb of the corolla.) 



1. STENHAMMJRIA. (Steenhammera, Reicheub., wrongly written.) Nutlets 

 very smooth and shining, acute, fleshy-herbaceous, in age becoming utricular ; the 

 scar small : corolla short, 5-lobed ; the crests in the throat evident. 



M. maritima, Don. Very smooth, pale and glaucous, much branched and spreading : 

 leaves fleshy, ovate, obovate, or spatulate-oblong, an inch or two in length, upper surface 

 sometimes becoming pustulate : flowers small (3 or 4 lines long) on long and slender pedi- 

 cels : tube of the blue or whitish corolla hardly as long as the limb and shorter than the 

 ovate-triangular lobes of the calyx : filaments rather narrower and much longer than the 

 anthers. Syst. iv. 320. Cerinthe maritima, Dill. Elth. t. 65. Pulmonaria maritima, L. ;

 (Greenland, N. Eu., & Asia.) 



2. EUMERTENSIA. Nutlets dull and with obtuse angles if any, wrinkled or 

 roughish when dry. (Corolla commonly villous inside near the base, and below 

 sometimes with a 10-toothed ring.) 



* Corolla trumpet-shaped, with spreading border nearly entire; the plicate crests in the throat 

 obsolete : filaments slender, much longer than the oblong-linear anthers : hypogynous disk pro- 

 duced into two opposite narrow lobes which become as high as the ovary. 



M. Virginica, DC. Very smooth and glabrous, pale, a foot or two high : leaves obovate 

 or oblong, veiny, or the lowest large and rounded and long-petioled : racemes at first short 

 and corymbose : flowers on nodding slender pedicels : corolla purple and blue, an inch 

 long, between trumpet-shaped and salverform, many times exceeding the short calyx. 

 M. pulmonarioides, Roth, Cat. Pulmonaria Virginica, L. ; Sims, Bot. Mag. t. 160. (Trew, 

 PI. Sel. t. 42.) Alluvial banks, New York to Minnesota, S. Carolina in the mountains, 

 and Tennessee : fl. spring ; not uncommon in gardens. 



* * Corolla (blue, rarely white) with conspicuously 5-lobed limb, which above the throat (i.e. 

 the whole expanded upper portion) is usually open-campanulate ; the small crests in the throat 

 obvious and commonly puberulent or pubescent. 



H Filaments enlarged, as broad as the anthers and shorter or only a little longer, always inserted 

 in the throat of the corolla nearly in line with the crests: style long and capillary', generally 

 somewhat exserled. (There are traces of some dimorphism as to reciprocal length of filaments 

 and style, at least in one species.) 



H- Tube of the corolla twice or thrice the length of the limb and of the calyx. 



M. oblongifolia, Don, 1. c. A span or so high, smooth or almost so : leaves mostly 

 oblong or spatulate-lanceolate, rather succulent, and veins very inconspicuous : flowers in 

 a somewhat close cluster : lobes of the 5-parted or deeply 5-cleft calyx lanceolate or linear, 

 mostly acute : tube of the corolla 4 or 5 lines long, narrow ; the moderately 5-lobed limb 

 barely 2 lines long. Hook. Kew Jour. Bot. iii. 295 ; Watson, Bot. King, 238. Pulmonaria 

 oblongifolia, Nutt. in Jour. Acad. Philad. vii. 43. Lithospermnm maryinatum, Lehm. in Hook. 

 Fl. ii. 86. Mountains of Montana to the borders of British Columbia, and south to 

 Nevada, Utah and Arizona, at 6-9,000 feet. On moist slopes ; flowering early. 

 ++ ++ Tube of the corolla little or not twice longer than the throat and limb. 



Stems mostly tall, 1 to 5 feet high: loaves ample and mainly broad, veiny; the upper with 

 very acute or acuminate apex; the lowest ovate or subcordate (usually 3 or 4 inches long and 

 long-petioled) : calyx deeply 5-parted. 



M. Sibirica, Don, 1. c. Pale and glaucescent, glabrous and smooth or nearly so, very 

 leafy : cauline leaves oblong- or lanceolate-ovate, hirsute-ciliolate : short racemes panicled : 

 calyx-lobes oblong or oblong-linear, obtuse, commonly ciliolate, half or a quarter the 

 length of the tube of the bright light-blue corolla ( this and the limb each about 3 lines 

 long). Gray, 1. c. Pulmonaria Sibirica, L. Spec. i. 135, not Pall. P. denticulata, Roam. &
