Type species
The type species (holotype) of the genus Ptilota is Ptilota plumosa C.Agardh.

Status of name
This name is of an entity that is currently accepted taxonomically.

Type information
Type locality: Ad caput bon. sp. Spec. ded. Desfontaines. Com. de Sternberg (Agardh 1822: 387). Lectotype: LD Ag. no. 20101 (Bruce & Saunders 2016 '2017': 40). Notes: Although listed as being from the Cape of Good Hope, the type is more like to have been collected from the Monterey Peninsula, California. Dawson (1962: 74) notes that the type is a specimen marked "e coll. Haenkiana", so Agardh's entry clearly was an error. TadeĆ” Haenke (1761-1816) came to the west coast of North America with the Malaspina expedition in 1791. His collections were one of the first large botanical collections from the area. He made his mark exploring North and, especially, South America, the Philippines, and the Mariana Islands; he visited the Monterey Peninsula around 1792.

Origin of species name
