solitary or few, erect, unbranched or branched, hairs spreading, short to long, ± stiff, mixed with short stipitate-glandular ones.

few to several, erect or ascending, unbranched or branched, sometimes with short, leafy axillary shoots, hairy, sometimes glabrate proximally, hairs spreading to retrorse, medium length to long, soft, eglandular, often mixed distally with shorter stipitate-glandular ones.
