SYNOPSIS OF THE FLORA OF COLORADO. 9 
HESPERIS PALLASII, Torr. & Gray. Fl. N. Am. 2, p. 666. Sparsely 
pubescent with clo osely £ appressed hairs fixed by the middle and acute at 
each end, minutely scabrous under the microscope; stems 3/6’ high, 
from a fusiform root; spe al — numerous, linear or lanceolate- lin: 
ear, sparingly toothed d,+1’-13’ long, tapering into a petiole; raceme 
short; pedicels much shorter than the flow ers; flowers large for the size 
of the plant; upper cauline leaves linear; sepals oblong, obtuse, with 
Searious margins, gibbous at base, 4” long; petals with a long, broa 
pale-colored claw which,exceeds the sepals; limb round-obov ate, purples 
anthers cordate at base; ovary hairy ; stigma capitate, somewhat 2 
igma, which do not 
separate this plant from the genus Hesperis. In all its other characters 
it seems to accord well with the brief description of Pursh’s Cheiranthus 
Pallasii. The specimens are in flower only, with no anne siliques.—
