- Dudleya brevifolia, is a rare succulent plant known by the common name short-leaved liveforever, short-leaved dudleya or rarely the Del Mar Hasseanthus. It is an edaphic endemic that only grows on the mesas of the most ancient marine terraces, hiding in the vicinity of ironstone concretions. The leaves are deciduous, and disappear after the inflorescence develops. The small white flowers are star-shaped with a yellow center. After flowering, any above ground trace of the plant will disappear, and it survives under the earth with a starch-rich subterranean caudex. Dudleya brevifolia is only found on coastal mesas along a small strip of coast in San Diego County, California. It was formerly a subspecies of the similar Dudleya blochmaniae, and was not recognized as a distinct species because both plants grew and hybridized together. However, the habitats with the intermediate populations were razed for residential development, and with these populations destroyed, Dudleya blochmaniae subsp. brevifolia was elevated to species status as Dudleya brevifolia. Populations continued to be extirpated until the plant was protected. Currently, Dudleya brevifolia is only found in 5 locations in the world, in an area roughly 8 square miles (21 square kilometres) centered around Torrey Pines State Park. It is of conservation concern, as the remaining populations have become fragmented and are threatened by continued disturbance and declining populations at some sites. (en)
