Agalinis viridis
Agalinis laxa
Agalinis viridis is tolerant of mowing and grazing; plants severed at mid stem will flower vigorously from the proximal nodes

Agalinis laxa occurs in northeastern South Carolina and is expected to occur in southeastern North Carolina; it is most common near the coast in Georgia and northeastern Florida but is found sporadically on the coastal plain as far south as Hernando County, Florida. In the field, A. laxa is most easily confused with A. tenella; both have laxly spreading branches, widely spaced leaves, long pedicels subtended by much shorter bracts, and inflorescences with some pseudoterminal flowers. Agalinis laxa is most easily differentiated from A. tenella by pedicels to 40 mm in fruit, shorter and narrower corollas, straight corolla throats, pilose abaxial corolla lobes, and black seeds. Agalinis tenella has larger gibbous corollas, glabrous abaxial corolla lobes, and golden yellow seeds.
