Layia carnosa
Also called Beach Layia
Layia carnosa is a species of flowering plant in the family Asteraceae known by the common name beach tidytips, or beach layia. It is endemic to California, where it lives in coastal habitat. It is known from several areas of mostly fragmented or relict sand dune habitat, and it was listed as an endangered species in California. On March 31, 2022, the category was changed from endangered species to threatened species by the US Department of the Interior Fish and Wildlife Service.
Beach layia germinates during the rainy season between fall and midwinter, blooms in spring (March to July), and completes its life cycle before the dry season (July to September). Populations tend to be patchy and subject to large annual fluctuations in size and dynamic changes in local distribution associated with the shifts in dune blowouts, remobilization, and natural dune stabilization that occur in the coastal dune ecosystem. Beach layia plants often occur where sparse vegetation traps wind-dispersed seeds, but causes minimal shading. Seeds are dispersed by wind mostly during late spring and summer months. Additionally, beach layia is self-compatible (i.e., able to be fertilized by its own pollen), is capable of self-pollination, and is visited by a variety of insects that may assist in cross-pollination . Although the role of pollinators is currently unclear, sexual reproduction does add to genetic diversity.
