Discussion | Agalinis pulchella is an uncommon species in the easternmost area of its range and is common only westward in southeastern Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Plants of Agalinis gattingeri are most often confused with those of A. skinneriana and A. tenuifolia. They can be distinguished by features discussed under 33. A. tenuifolia. Agalinis gattingeri is also confused with A. skinneriana from which it can be separated by the mostly solitary flowers on lateral branches of A. gattingeri versus the well-formed central raceme of A. skinneriana; pink-purple corollas of A. gattingeri versus the pale pink to nearly white corollas of A. skinneriana; the flexible, well-branched stems of A. gattingeri versus the strict, brittle, mostly simple to few-branched stems of A. skinneriana; and the pilose abaxial corolla lobes in A. gattingeri versus the glabrous external corolla lobes of A. skinneriana. Isolated populations of A. gattingeri on the islands of Georgian Bay, Ontario, have calyx lobes to 2.6 mm and hairs on the calyx tube, characteristics not seen elsewhere in the species.
