Dudleya abramsii is a succulent plant known by the common name Abrams' liveforever. The epithet abramsii commemorates LeRoy Abrams.[1] It is native to California and northern Baja California, where it grows in rocky areas in a number of habitat types. It is a fleshy perennial forming a small basal cluster of leaves around a central caudex. The thick, waxy leaves are triangular to oblong and usually pointed, reaching up to 11 centimeters in length, but often remaining much smaller. The entire rosette is generally only a few centimeters wide. The inflorescence is a mostly erect, branching stem lined with pointed bracts and bearing up to 15 flowers. The flower has five small, thick sepals at the base of five pale yellow petals each about a centimeter long.

There are several subspecies:

Dudleya abramsii subsp. abramsii – native to the Peninsular Ranges of California and Baja California
Dudleya abramsii subsp. affinis (San Bernardino Mountains liveforever) – endemic to the San Bernardino Mountains near the edge of the Mojave Desert
Dudleya abramsii subsp. bettinae (San Luis Obispo serpentine dudleya or Betty's liveforever) – endemic to the coastal serpentine of San Luis Obispo County, California
Dudleya abramsii subsp. murina (San Luis Obispo or mouse-leaved dudleya) – endemic to coastal San Luis Obispo County
Dudleya abramsii subsp. parva (Conejo dudleya) – endemic to the Santa Monica Mountains of Ventura County and treated as a federally listed threatened species[2]
