 basal leaves 5-6 cm, long, narrowly oblanceolate, strigose on both 

 sides^ often callous-denticulate ; stem-leaves linear and sessile, and 

 reduced ; heads about 3, 6 mm. high; bracts linear-subulate, 

 acuminate, in about 2 series, nearly equal, densely strigose; rays 

 numerous and very narrow, white, about 8 mm. long.

 by the appressed, dense, strigose pubescence.
