Dudleya abramsii is a species complex of succulent plants native to California and parts of Baja California. There are numerous subspecies, some critically endangered, with varying habits and lifestyles, but most often characterized by a smaller size, yellow flowers, and an affinity for rocky habitats. The subspecies may be polyphyletic.[1]
Dudleya abramsii is a fleshy perennial forming a small basal cluster of leaves around a central caudex. The habit of Dudleya abramsii is growing in either solitary rosettes or in caespitose forms. The thick, glaucous leaves are lance-oblong to lanceolate, reaching up to 11 centimeters in length, but often remaining much smaller, usually 2 to 30 mm long, and 3 to 20 mm wide. The entire rosette is generally only 0.5 to 15 cm wide. The inflorescence is a mostly erect, branching stem lined with pointed bracts and bearing up to 15 flowers. The inflorescence has a peduncle 2 to 25 cm tall, and 1 to 6 mm wide. The lower bracts are 4 to 40 mm large, and the pedicels are anywhere from 0.5 to 7 mm long. The flower has five small, thick sepals at the base of five pale to cream yellow petals each roughly 8 to 13 mm long. The keel of the flower is tinged with fine, purple to red lines.[2]
There are several subspecies, and many former subspecies with differing recognition. Flora of North America and The Jepson Manual have elevated Dudleya parva to a species, while other subspecies have been moved to Dudleya cymosa
The following subspecies are recognized in the 2012 Jepson eFlora:
D. abramsii is native to California and northern Baja California, where it grows in rocky areas in a number of habitat types.
