 persistent stems, imbricated or crowded leaves and solitary or 

 somewhat umbellate small flowers. Calyx campanulate, 5-lobed, 

 persistent. Corolla tube equalling or surpassing the calyx, some- 

 what inflated above; the throat more or less contracted and 5- 

 fornicate beneath the sinuses. Stamens included, distinct, with 

 short filaments and blunt anthers. Ovary 5-ovuled : style filiform. 

 Capsule turbinate, 1 or 3-seeded. 



D. dentata Watson Proc. Am. Acad, xvii, 375. Canescent with a 

 firm mostly dense pubescence: rather stout, branching: leaves rosulate at 

 the nodes, oblong, obtusish, mostly with 1-3 blunt teeth on each side 

 toward the summit, 4-6 lines long: peduncle an inch long, bearing a sim- 

 ple, few-flowered umbel : pedicels very unequal : calyx narrowed at base, 

 3 lines long in fruit: the acuminate lobes nearly as long as the tube: 

 capsule oblong, slightly stipitate, equalling the calyx-tube. On high 

 ridges, Yakima Co., Washington. 



D. laevigata Gray Proc. Am. Acad, xvi, 105. Depressed cespitose: 

 leaves glabrous or with a few minute and scurfy deciduous branched 

 hairs, not at all ciliate, entire, or with 1 or 2 teeth toward the summit, ob- 

 long-lanceolate, obtuse, mainly in rosulate radical or simply proliferous 

 clusters, 2-3 lines long: peduncles short, scurfy-pubescent, 1-5-flowered: 

 bracts of the involucre oval or ovate, short : corolla bright red, its tube 

 almost twice as long as the ovate acute lobes of the calyx. On bluffs

 Small annual or perennial herbs with tufted leaves and small

 Corolla salverform or f unnelform ; the tube short, not longer than

 cluded, distinct, with short filaments and short blunt anthers. 

 Style mostly short: stigma capitellate. Capsule short, 5-valved 

 from the apex, few to many-seeded. 



A. septentrionalis L. Sp. 203. Leaves all rosulate at the summit of 

 the slender annual root, lanceolate or oblong-lanceolate, narrowed at base, 

 often into a winged petiole, from irregularly denticulate to laciniate- 

 toothed, 6-12 lines long: scapes usually numerous, 2il0 inches high, sev- 

 eral to many-flowered : bracts of the small involucre subulate : pedicels 

 filiform, 1-3 inches long: calyx-tube obpyramidal, white or reddish, with 

 subulate acute green lobes mostly shorter than the tube and rather 

 shorter than the obovate lobes of the corolla : capsule ovoid, shorter than 

 the calyx : seeds ovate, flattish. In open places, Brit. Columbia to Cali- 

 fornia and the Rocky Mountains. Europe and the Arctic sea coast. 



A. filiformis Retz. Obs. ii, 10. ? Annual : leaves ovate, obtuse, nar- 

 rowed at base to a winged petiole, entire, 2 lines long: scapes filiform, 

 1-10 inches high: bracts of the involucre minute, subulate: pedicels fili- 

 form, an inch long or less : calyx-tube hemispherical, green, with short 

 triangular lobes : tube of the corolla at length much longer than the calyx, 

 the short ovate lobes closely reflexed : capsule ovoid, much longer than 

 the calyx : seeds globular, minutely tuberculate. Edge of water near
