Swallenia

provided by wikipedia EN

Swallenia is a rare genus of plants in the grass family, found only in Death Valley National Park, California.[2][3]

The only known species is Swallenia alexandrae, known by the common names Eureka dunegrass[4] and Eureka Valley dune grass. This genus was named for American botanist Jason Richard Swallen (1903-1991). The species was named for American philanthropist and paleontological collector Annie Montague Alexander.[5]

Description

This is a rare plant endemic to Inyo County, California, where it is found on a single isolated dune system, the Eureka Valley Sand Dunes in the Eureka Valley of the Mojave Desert, within Death Valley National Park.[6][7]

Description

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.[8]

Endangered status

This is a federally listed threatened species of the United States.[9] 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.[1]
