Flora of North America species comparison

few to several, erect or ascending, sometimes decumbent at base, unbranched or branched, hairs spreading to retrorse, short, scabrid below inflorescence, sometimes becoming medium length to long, soft to stiff, mixed with short stipitate-glandular ones in inflorescence.

few to many, erect or ascending, often branched distally, sometimes unbranched, sometimes with short axillary shoots, proximal hairs retrorse to appressed, short to moderately long, distal hairs spreading, longer, soft, often mixed with short stipitate-glandular ones.
