 leaves tiesliy, 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-

§ 2. EuJiERTENSiA. 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, Koth, Cat. Pulmonuria 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 consiiicnously 5-lobed limb, which above the throat (i. e. 

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

 obvious and conuuonly 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 lilament's 

 and style, at least in one species.) 



•H- Tube of the corolla twice or thrice the lengtli 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, 2:38. Puhnonaria

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



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

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

 very acute or acuminate apex; the lowest ovate or subcordate (usuallj' •! or 4 inches long and
