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.)

Agalinis flexicaulis is of conservation concern because of its limited distribution. The species is currently known from Bradford County.

Plants of Agalinis flexicaulis are distinguished by their weakly ascending main branches, which become more drooping and lax as they mature. It is most easily confused with the more widespread A. obtusifolia and A. tenella. Agalinis flexicaulis is differentiated from these species by characters in the key.
