the rosette. Bolting inflorescences are generally 

 larger and leafier than axillary inflorescences. 

 An individual rosette may produce axillary 

 inflorescences for numerous years, while bolting 

 rosettes always die. Some rosettes produce 

 axillary inflorescences for one to many years 

 before either dying or bolting and then dying. 

 Others bolt once and die. Axillary flower stalks 

 are unbranched, while bolting inflorescences are 

 often branched. Each flower" has four white petals 

 0.25-0.5 in long and ca . 0.2 in wide. The flowers 

 are close together on the stalk but become further 

 apart as they mature into fruits. Fruits are 1-2 

 in long and ca. 0.05 in wide and held nearly erect 

 by the stalks that may be up to 0.5 in long. The 

 fruits are densely hairy, and each side of the 

 fruit contains a single row of round seeds ca . 

 0.05 in diameter. 



TECHNICAL DESCRIPTION: Perennial with a simple or 

 branched caudex, densely pubescent throughout with 

 fine dendritically branched trichomes; stems erect 

 to somewhat decumbent at base, simple or few 

 branched, 1-3 dm high; leaves hoary, dimorphic; 

 basal leaves petiolate, spatulate to linear 

 oblanceolate, entire or with a few broad teeth in 

 the blade area, 1-3 cm long, 2-4 mm wide; cauline 

 leaves sessile, entire or the lower with a few 

 teeth, oblong, acute, sparingly auriculate to 

 nonauriculate, 7-20 mm long; inflorescences 

 usually congested, sepals oblong, nonsaccate, 

 densely pubescent, 6-7 mm long, ca . 2 mm wide; 

 petals purplish, obovate, not unguiculate, 

 narrowing gradually from blade to point of 

 insertion, 9-13 mm long, 3-5 mm wide; fruiting 

 pedicels erect to slightly divaricately ascending, 

 straight, 6-10 mm long; siliques erect, congested, 

 usually appressed to rachis, straight to slightly 

 curved inward, 3-5 cm long, ca. 1.5 mm wide, 

 valves densely pubescent, compressed between 

 seeds; styles ca . 1 mm long; seeds in a single 

 row, suborbicular to slightly longer than broad, 

 narrowly winged-margined all around, ca. 1.2 mm in 

 diameter, mucilaginous when wetted; cotyledons 

 accumbent (Rollins 1984) 



It should be remembered that the above description 

 was based on a very limited amount of material. 

 An additional, more recent technical description 

 can be found in Rollins (1993).
