Agalinis neoscotica
Agalinis plukenetii
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 plukenetii can be bushy, relatively large, and showy. Agalinis plukenetii is a common component of dry to xeric roadsides in the southern portions of its range. It readily colonizes open, dry ground with very little vegetation. It was reported in South Carolina (F. W. Pennell 1935) based on a specimen that has little label data; its occurrence there is doubtful.
