SCKOFHULAKIACE2E. (F1GWORT FAMILY.) 283 



usually bluish or pale with blue stripes : capsule oblately orbicular and obcor- 

 date. Throughout the continent. 



# * * Low annuals: flowers in the axils of ordinary or bract-like commonly 



alternate leaves, very short-pedicelled. 



6. V. peregrina, L. Glabrous, or above minutely pubescent or glandu- 

 lar : stem and branches erect, a span or two high : leaves thickish ; lowest 

 petioled and oblong or oval, dentate ; the others sessile, from oblong to 

 linear-spatulate ; uppermost more bractlike and entire : capsule orbicular and 

 slightly obcordate. Throughout the continent. " Neckweed." 



11. GERARDIA, L. 



Erect and branching herbs ; with mainly opposite leaves, the uppermost 

 reduced to bracts of the racemose or paniculate showy flowers. Our species 

 belong to the section with purple or rose-colored flowers and linear or filiform 

 cauline leaves, the herbage blackening in drying. 



1. G. aspera, Dougl. Stems and branches strict: leaves rather erect, 

 strongly hispidulous-scabrous, all filiform-linear: pedicels mostly equalling and 

 sometimes moderately exceeding the calyx, erect: calyx-lobes deltoid-subulate or 

 triangular-lanceolate from a broad base, about half the length of the tube : anthers 

 obscurely if at all mucronulate at base. On the plains within the eastern limit 

 of our range, and extending eastward to Wisconsin and Illinois. 



2. G. tenilifolia, Vahl. Smooth or usually so, about a foot high, panicu- 

 lately much branched, but the inflorescence racemose : leaves mostly narrowly 

 linear, equalling the lower but mostly shorter than the uppermost pedicels: calyx- 

 teeth very short : corolla about a half-inch long : anthers woolly, and cuspidate- 

 mucronate at base. 



Var. macrophylla, Benth. Stouter: larger leaves lto2 inches long 

 and almost 2 lines wide, scabrous : pedicels ascending : calyx-teeth usually 

 larger : corolla little over a half-inch long. From Colorado to W. Iowa and 

 W. Louisiana. 



12. CAST ILL El A, Mutis. PAINTED-CUP. 



Herbs with alternate entire or laciniate leaves, passing above into usually 

 more incised and mostly colored conspicuous bracts of a terminal spike : the 

 flowers solitary in their axils, red, purple, yellowish, or whitish ; but the 

 corolla almost always duller-colored than the calyx or bracts. 



* Annuals with virgate stems, mostly tall and slender : leaves and bracts all linear- 



lanceolate and entire ; the latter or at least the upper with red linear tips. 



1. C. minor, Gray. A foot or two high, pubescence villous or soft- 

 hirsute : flowers all pedicellate, the lower rather remote in the leafy spike : 

 calyx gibbous and broadest at base, wholly green, about equally cleft before 

 and behind to near the middle : corolla narrow and straight, to f inch long, 

 yellow; galea (upper lip) very much longer than the small lip, much shorter 

 than the tube. Bot. Calif, i. 573. C. affinis, var. minor, Gray. In wet 

 ground, from Nebraska to W. Nevada and New Mexico.
