Dudleya lanceolata
Dudleya abramsii
Dudleya lanceolata is wide-ranging, from Monterey and western Kern counties southward through San Diego County, variable, and ill-defined. It varies locally in size of parts and in flower color but does not seem easily divisible into smaller units. N. L. Britton and J. N. Rose (1903, 1905) proposed seven additional species of southern California or of unstated origin that seem best included here. On the basis of 18 or more well-scattered collections, it is tetraploid; it seems best defined partly on that basis. Similar plants from Aliso Canyon, Orange County, are octoploid (C. H. Uhl and R. V. Moran 1953, as D. sp. aff. D. lanceolata); this is one of several scattered coastal populations with the caudex elongate. Another is D. elongata Rose, from near San Pedro, of which later collections are tetraploid.

Subspecies 7 (7 in the flora).
Dudleya abramsii, a widespread diploid, is largely montane, growing mostly on granite or limestone, but its northwestern subspp. bettinae, murina, and setchellii are local at lower elevations, on serpentine. It forms small clumps, 2–11 cm in diameter. From the widespread diploid D. cymosa, generally a larger plant, it is nearly distinct in its mostly cespitose, narrow-leaved rosettes and simple cyme branches, and distinctively, the antisepalous stamens are adnate higher on the corolla tube than the epipetalous and are often 1–2 mm longer. The petals commonly much exceed the stamens and pistils, and the pistils are attenuate. Both species are variable, and subsp. costatifolia is somewhat intermediate.
Five of the six subspecies are very similar, with only small differences, and only subsp. costatifolia is more distinctive.
