Endemic to San Diego County occurring only along the coast between Del Mar and La Jolla .
Known Populations in San Diego County
There are five occurrences of this species, including an occurrence in MU 6 at Carmel Mountain Preserve and four occurrences in MU 7 at Crest Canyon, Skeleton Canyon, Torrey Pines State Reserve, and Torrey Pines Extension .
Occurs on sandstone bluffs and in sandy openings in chamise chaparral on Carlsbad gravelly loam soils in association with small iron concretions [1,3]. It is often in areas with native annual forbs and while not a wetland species it occurs in areas where soils remain saturated for a relatively long period after rain .
Taxonomy and genetics
in the family Crassulaceae.
Life history demography
Herbaceous perennial .
Large annual fluctuations in population size .
Pollination seed dispersal
Pollinated by insects . Seeds are thought to be self-dispersed.
Trampling by hikers, bikers, dogs and horses, illegal trails, invasive non-native plants and erosion . A small number of occurrences in close proximity make the species vulnerable to loss from catastrophic disturbance and environmental stochasticity.
Special considerations: Very small and can be difficult to detect when not flowering .
