Description
“The entire plant covered with stiff nonglandular hairs. The stem can grow up to 75cm tall, widely and stiffly branched, the longest branches arising near the base of the plant. The leaves are deeply divided with segments borader than 1 mm. The flowers are solid yellow, 1 cm long, hairy on the exterior. The capsule is ovoid, 5 mm long, covered with glandular hairs.” – Musselman and Mann 1978.

Deyrup conducted a study and observed these bees, Augochlorella aurata, Augochloropsis sumptuosa, Dialictus placidensis, Anthidiellum notatum rufimaculatum, A. perplexum, Coelioxys sayi, Megachile brevis pseudobrevis, M. mendica, M. petulans, and Bombus impatiens, on S. pectinata (2002).
