Agalinis densiflora, commonly known as Osage agalinis, Osage false foxglove, Osage Plains false foxglove, or fine-leaf hairy-foxglove, is a species of flowering plant in the family Orobanchaceae. It is an annual herb endemic to the south-central United States, where it occurs in Kansas, Oklahoma, and Texas.[2][3][4]

Taxonomy
Agalinis densiflora was originally described as Gerardia densiflora by George Bentham in 1835.[5][2] It was later transferred to Agalinis by Sidney Fay Blake in 1918, giving the accepted combination Agalinis densiflora (Benth.) S.F.Blake.[5][2] Although older sources placed the taxon in Scrophulariaceae, modern treatments place it in Orobanchaceae.[5][2][1]
Synonyms include Gerardia densiflora, Otophylla densiflora, Tomanthera densiflora, and Otophylla drummondii.[2]
Distribution and habitat
Agalinis densiflora is endemic to Kansas, Oklahoma, and Texas.[2][3][4]
It grows in prairies, dry limestone areas, grassy roadsides, pastures, and well-drained calcareous soils.[4][1]
Conservation
NatureServe ranks Agalinis densiflora as , indicating that it is globally vulnerable.[1] The rank was last reviewed on 7 April 2025.[1] The species is ranked N3 in the United States and S2 in Kansas, Oklahoma, and Texas.[1] NatureServe estimates about 41 occurrences rangewide and lists potential threats including development, conversion to pasture, oil development, rights-of-way maintenance, invasive species, and severe overgrazing of grassland habitat.[1] The species has no status under the United States Endangered Species Act.[1]
