Description
Agalinis pulchella is a dioecious annual forb.[1] 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.[3] Cotyledons are orbicular to orbicular-ovate and 0.8-1.3 mm wide and long.[4] Seeds have a striate-tuberculate radial wall.[5]
Distribution
This species is found from Texas, eastward to Florida and Georgia.[1][3]
Ecology
Habitat
A. pulchella is found in pine savannas and sandhills of the southeastern United States.[2] It has also been described as occurring in dry open sandy longleaf-pinelands on the southeastern coastal plain.[3] It has also been observed in clearcut areas in a soil disturbed sand ridge. [6]
Phenology
In North America, this species flowers in September and fruits in October.[6][3]
Herbivory and toxicology
Members of the Agalinis genus host larvae of the common buckeye butterfly (Junonia coenia) in Florida.[7]
