Description

Agalinis pulchella is a dioecious annual that grows as a forb/herb.[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 were 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] Another paper describes A. pulchella being found in dry open sandy longleaf-pinelands on the southeastern coastal plain.[3]

Phenology

In North America, this species flowers in September and fruits in October.[3]

Use by animals

Agalinis species, including this one, host larvae of the common buckeye butterfly (Junonia coenia) in Florida.[6]
