Deinandra conjugens
Also called Otay Tarplant
Deinandra conjugens (syn. Hemizonia conjugens) is a rare species of flowering plant in the family Asteraceae known by the common names Otay tarplant and Otay tarweed. It is native to a small section of far northern Baja California in Mexico, its range extending north into San Diego County, California, in the United States. One isolated population has been reported from the hills east of Cayucos in San Luis Obispo County.
Deinandra conjugens is threatened by habitat destruction and degradation. It was federally listed as a threatened species in 1998.
Deinandra conjugens grows in clay soils in several types of habitat, including grassland and maritime and inland coastal sage scrub. It tolerates some disturbance in its habitat, and low levels of grazing and road maintenance activities such as mowing are probably beneficial.
