DistributionOf historical occurrence, collected in 1950 in Brunswick County. This represents the northeastern edge of the species' range.

This is a Southern species, quite scarce north of FL. It ranges from southeastern NC to southern FL and west to MS.
AbundanceFormerly extremely rare, but now historical (SH State Rank), and may well be extirpated (SX). This is a State Special Concern - Historical species, though technically the listing is for the subspecies in NC.
HabitatThis species is found in slightly drier habitats than is S. cassioides in its range. It was found in NC in dry Longleaf Pine (Pinus palustris) habitats, such as pine/scrub oak sandhills and drier pine flatwoods.

PhenologyBlooms from July to October, and fruits shortly flowering.
IdentificationThis species is rather similar to S. cassioides, in that it is bushy-looking, with spreading branches, growing up to 2 feet tall. However, in this species the pinnately divided leaves have lanceolate segments as opposed to linear ones. Also, the yellow flowers do not have a dark red band around the base of the 5 petals.
Taxonomic CommentsThe subspecies found in the Carolinas is the nominate one -- S. pectinata ssp. pectinata.
