Cacalia suffruticosa Linnaeus, Systema Naturae, ed. 12, 2: 535; Mantissa Plantarum: 109. 1767, nom. illeg.

"Habitat in Brasilia. Arduini." RCN: 6035.

Replaced synonym: Cacalia linifolia Ard. (1764) .

Type not designated.

Current name: Porophyllum linifolium (Ard.) DC. ( Asteraceae).

Note: Linnaeus cited, as a synonym, an account of the species published by Arduino in 1764, in which the binomial C. linifolia Ard. was adopted. Linnaeus’ name is therefore illegitimate. Johnson (in Univ. Kansas Sci. Bull. 48: 239. 1968) wrongly cited this as " Cacalia linifolia L. " as published in Mant. Pl.: 109. 1767, though the epithet clearly came from Arduino. Johnson stated that he had seen a photo "of type from Linnean herbarium". Presumably this is likely to have been 976.2 (LINN) - Arduino 20 - with the epithets “fruticulosa”, and “suffruticosa” added by Smith. However, further study would be necessary to establish its link with Arduino’s name.
