DistributionCoastal Plain and Sandhills region; scarce in the northern Coastal Plain. Disjunct to East Flat Rock bog in Henderson County. In Dare County found in seepy soil on Roanoke Island; in coastal New Hanover County found at the edge of an interdune pond.

Southeastern VA to southeastern GA; disjunct to a few mountain counties in NC and SC.
AbundanceLocally common in the southern Coastal Plain, including the Sandhills; somewhat less numerous elsewhere in the province, but essentially absent in the northern counties. Very rare in the southern Mountains and along the eastern edge of the Piedmont.
HabitatWet to moist Longleaf Pine (Pinus palustris) savannas and flatwoods, pocosin ecotones, blackwater streamhead ecotones, clearings and openings in blackwater swamps; montane seepage bog.
PhenologyFlowering and fruiting May - early July (-late July in mountains).
IdentificationThis is a very handsome plant when in bloom. Plants grow mostly 2-5 feet tall, with only 3-7 leaves, the lower ones elliptic to almost linear in outline and with a long stem, the upper ones much reduced and generally stemless. On most plants, there are at least a few stem leaves that possess a pair of slender lobes at the base of such leaves; however, lobes are absent in some plants. The inflorescence is very open, with long branches that curve out and then up; each branch terminated by one head. The rays are bright golden-yellow, and the disks brown.
Taxonomic CommentsThe type location is in "Pembroke, N.C." (Robeson County).
