Agalinis neoscotica
Agalinis oligophylla
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.

Plants of Agalinis oligophylla are rare in the easternmost portions of the range; they are abundant farther west into Texas. Agalinis oligophylla is often the last species of Agalinis to begin flowering, usually in late September, sometimes not until mid October and often remains in flower well into November. Unbranched plants of A. oligophylla can be confused with A. aphylla, with which it often shares the habitat. Agalinis oligophylla can be distinguished from A. aphylla by the longer leaves, more diffusely branched inflorescence, glabrous style, and the much later flowering period of A. oligophylla. Also, on the older buds of A. oligophylla the corolla is globular, but in A. aphylla the corolla on older buds is obovoid. Corollas of A. oligophylla are asymmetric; the adaxial side of the corolla throat is conspicuously shorter than the upcurved abaxial side of the corolla. The buds, pedicels, and capsules of A. oligophylla turn dark brown or blackish, and corollas turn dark purplish or pinkish brown when dried. These dark structures contrast strikingly with the pale green to gray (or reddish) branches and leaves.
