Taxonomic notes
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.
Distribution
“Combleaf seymeria is much more restricted in its distribution than senna seymeria (Seymeria cassioides) and also has a much broader host range. It prefers drier sites (such as turkey oak-scrub oak woods) than S. cassioides, but on rare occasions both may be found growing together. We have found no evidence of hybridization between the two species. In our previous studies S. pectinata parasitized yellow poplar, blackgum, water tupelo, pecan, sweetgum, green American sycamore, and four different pines. These species are not present in the communities where S. pectinata grows, which indicates a pathogen potential, especially on drier sites in the Deep South. “ – Musselman and Mann 1978.

Pollination
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).
The following Hymenoptera families and species were observed visiting flowers of Seymeria pectinata at Archbold Biological Station (Deyrup 2015):
Halictidae: Augochlorella aurata, Augochloropsis sumptuosa, Lasioglossum placidensis
Megachilidae: Anthidiellum notatum rufomaculatum, Anthidiellum perplexum, Coelioxys sayi, Megachile brevis pseudobrevis, M. mendica, M. petulans
