[4] It is a rosette-forming leaf succulent which has narrow pencil-shaped leaves that can often be found covered in a white epicuticular wax.

The thin, sprawling stems branch to form the clusters of rosettes, with plants creating a "clump" up to 40 cm wide.

The 5 to 15 bracts on the stem are ascending, linear-lanceolate to deltate-ovate, acute, with the lowermost 0.5 to 8 cm long and 2 to 5 mm wide.

australis, is found hybridizing where Dudleya albiflora meets it in the south near Puerto Faro San José.

attenuata, other specimens collected are instead basal to D. edulis and D. formosa, illustrating the gene flow where the species overlap.

The D. attenuata population in the United States is threatened by Border Patrol activity and trampling.
