''Cordylanthus mollis'' is a species of flowering plant in the broomrape family known by the common name soft bird's beak. It is endemic to California, where it is known in coastal and inland salt marshes in the Central Valley, particularly the Sacramento-San Joaquin River Delta. ==Subspecies== Both subspecies are rare, one treated as a federally listed endangered species. In general this is a grayish or purplish green annual coated in long whitish hairs, sometimes bristly and glandular. The woolly inflorescence is a spike of club-shaped white flowers enclosed in densely hairy sepals. Subspecies ''Cordylanthus mollis'' ssp. ''hispidus'', the hispid bird's beak, grows in alkaline and saline soils of marshes and playas in scattered locations throughout the Central Valley. Most of its habitat in the southern valley has been turned over for agriculture, leading to the extirpation of most of its populations there.〔(California Native Plant Society Rare Plants Profile: ssp. ''hispidus'' )〕 The even less common ''C. m'' ssp. ''mollis'' is known only from the coastal salt marshes and swamps of the inner Bay Area and Delta. It is federally listed as an endangered species. Threats to the survival of this subspecies include the invasive marsh plant ''Spartina patens'',〔(spartina.org Flyer )〕 and destruction of its native habitat by erosion and drainage of the marshland.〔(California Native Plant Society Rare Plants Profile: ssp.
