| Distribution | Two specimens were annotated as this species by Judith Canne-Hilliker in 1981. Craven County, pineland near Fort Barnwell, 13 Oct 1938, Godfrey 6772 & White (GH). New Hanover County, moist sandy pineland, Wilmington. 15 Oct 1912, Pennell 4902 (GH). Both ought to be annotated again, using the updated keys in FNA or Weakley (2022).

| Abundance | Very rare, if still present. As this is a difficult species to identify, very similar to A. virgata and somewhat to A. purpurea, it is likely that few if any present-day biologists are aware that this species might be lurking in the Coastal Plain. Thus, the website editors suggest a State Rank simply of SU (Undetermined), and a Watch List (W7) status. | |
| Habitat | Moist pinelands -- no doubt in Longleaf Pine (Pinus palustris) savannas. | |
| Phenology | Flowering late August to mid-October. | |
| Identification | This Agalinis is similar to A. purpurea and A. virgata, being rather tall, with the branches ascending, as in A. virgata. However, the leaves are extremely narrow -- filiform -- barely 1 mm wide; A. purpurea and A. virgata leaves are indeed linear but can range to about 4 mm wide (1/6-inch). The rose-purple flowers are similar, but average somewhat smaller than for A. purpurea. In general, the flowers are more in a slender and vertical raceme along a branch, and not scattered all over the bushier growth form as seen in A. purpurea. Thus, its appearance should resemble A. virgata but with even narrower leaves. | |
| Taxonomic Comments | This species has in the past been named as A. pinetorum, but has been lumped within A. harperi.
