Stylisma pickeringii (Torrey ex M.A. Curtis) A. Gray var. pickeringii . Pickering's Dawnflower. Phen: (May-) Jun-Aug (-Sep); Jul-Sep. Hab: Longleaf pine sandhills, usually in the driest, most barren, deep-sand areas, occasionally colonizing dry, disturbed areas in sandhills, such as sandy roadbanks, known from the Fall-line Sandhills, aeolian rims of Carolina bays, and sandhills on relict riverine dunes along Coastal Plain rivers. Dist: Var. pickeringii ranges from s. NC south through SC, GA, AL, and e. MS, with a disjunct area in the Pine Barrens of s. NJ, sometimes treated as a separate variety "caesariensis" (see synonymy).
ID notes: Stylisma pickeringii is easily recognizable by its growth form, with numerous stems arching from a central point, then trailing radially away, forming a mound 1-2 meters in diameter. The narrowly linear leaves are borne vertically.
Origin/Endemic status: Endemic
Taxonomy Comments: Fernald and Schubert (1949) named four varieties in this widely but disjunctly distributed species; Myint (1966) reduced this to two varieties, one eastern and one western.
