Agalinis neoscotica
Agalinis setacea
Agalinis neoscotica is rare in Maine, occurring only in Washington County on shores and tidal pools, and in adjacent eastern New Brunswick; it is most abundant in southwestern Nova Scotia and is reported from neighboring Grand Manan Island and Sable Island on the extreme northeastern edge of the range of Agalinis.
Features that characterize Agalinis neoscotica are narrow tubular corolla throats with red spots in two rows on the two yellow lines (the lines sometimes absent); corolla lobes that either project forward or are only slightly spreading; relatively small anthers, all held parallel to the filaments; two-lobed stigmas, obvious in live plants but rarely on dried specimens; both anthers and stigma included within the corolla throat; calyx in which the middle adaxial lobe is shortest and curved toward the corolla; bracts longer than both the pedicels and flowers they subtend and, sometimes, longer than the main stem leaves; and leaves with narrowed bases that terminate at a creaselike abscission zone. Agalinis neoscotica has a mixed mating system (H. M. Stewart et al. 1996). Self-pollination occurs in bud but delayed pollen germination allows for out-crossing. Stewart and J. M. Canne (1998) presented data that showed A. neoscotica flower development and morphology differ from those of A. purpurea.

Agalinis setacea is most common in North Carolina, South Carolina, and Virginia, and is much more rare or localized in other states.
Agalinis setacea is largely replaced toward the south and west on the coastal plain by A. plukenetii. Plants similar to A. setacea but with more slender leaves and stems, longer internodes, and racemes similar to those in A. plukenetii occur from the mid-western peninsula of Florida near Tampa east to Lake Wales area south to Sebring. F. W. Pennell (1920, 1929) referred these plants to A. stenophylla Pennell. That species may warrant recognition based on the examination of specimens from Tampa and along the Lake Wales Ridge.
