Description
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.

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).
