Discussion

Agalinis caddoensis is known only from two collections made by F. W. Pennell in 1913 and is most similar morphologically to A. navasotensis; see 22. A. navasotensis for a comparison. Agalinis caddoensis should be expected in northwestern Louisiana and eastern Texas and likely flowers in September as does A. navasotensis.
