Common name: St. Mark's false foxglove
Synonym: Gerardia pulchella Pennell.
Agalinis pulchella is a dioecious annual forb. It is dull green to purplish with stems 6-10 dm tall. Leaves are opposite, or sub-opposite, spreading, narrowly linear, acute, entire, with stems 2-3 cm long. Seeds are 0.5-0.7 mm long and broadly triangular to quadrangular. Cotyledons are orbicular to orbicular-ovate and 0.8-1.3 mm wide and long. Seeds have a striate-tuberculate radial wall.
A. pulchella is found in pine savannas and sandhills of the southeastern United States. It has also been described as occurring in dry open sandy longleaf-pinelands on the southeastern coastal plain. It has also been observed in clearcut areas in a soil disturbed sand ridge.
