''Cosmos pacificus'' is a Mexican species of plants in the sunflower family. It is native to southwestern and west-central Mexico from Sinaloa to Chiapas.〔(Melchert, Thomas E. 1990. Phytologia 69(3): 200-215 ) description, discussion, photographs, line drawings, distribution map〕 ''Cosmos pacificus'' is a branching annual up to 200 cm (80 inches) tall. Leaves and highly lobed and dissected. The plant produces many flower heads, each with pink to lavender ray florets and yellow disc florets.〔 The oldest name for the taxon is ''Cosmos caudatus'' var. ''exaristatus'', coined by Earl Edward Sherff in 1964.〔Sherff, Earl Edward 1964. Brittonia 16: 66〕 In elevating the taxon from varietal level to species, Melchert opted to forego the common (but not mandatory)〔(International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) ) article 11.2〕 custom of using the varietal epithet as specific epithet, choosing instead to create a new name, ''Cosmos pacificus''.〔 ;Varieties〔〔(Tropicos, Cosmos pacificus Melchert )〕 * ''Cosmos pacificus'' var.
