Cryptantha longifolia ≡ Eritrichium longifolium Phil., Anales Univ. Chile 90: 522. 1895. Type: Chile. Región del Biobío: La Polcura, Jan. 1888, R.A. Philippi s.n. (first-step lectotype, designated by Johnston 1927, pg. 57: SGO; second-step lectotype, designated here: SGO [SGO000004102 digital image!]; isolectotypes: GH [GH00096556 digital image!], SGO [SGO000004103 digital image!]).

Note.

Rudolph A. Philippi (1895) based the diagnosis of Eritrichium longifolium on a collection he made in La Polcura, Chile. Johnston (1927) referred to a specimen lodged at SGO as the “type” of the name. However, two duplicates studied and annotated as " Eritrichium longifolium " by Philippi were located there in agreement with the protologue. Thus, Johnston’s (1927) choice is here interpreted as a first-step lectotypification. In order to narrow this broad designation, the specimen SGO000004102 is here selected as a second-step lectotype.
