Swallenia alexandrae is a coarse, tufted perennial grass which grows in sand from thick rhizomes. Its stiffly erect clums, sharp-leafed grass, and erect pale-colored panicle inflorescences are diagnostic.
This is a federally listed endangered species of the United States, and an IUCN listed Critically endangered species. The main threat to the species survival has been off-roading, which is no longer permitted in its habitat. Trespassing off-roaders and campers are still a threat to the five remaining occurrences.
