(first-step lectotype, designated by Johnston 1927, pg. 61: SGO; second-step lectotype, designated here: SGO [SGO000004033 digital image!]; isolectotypes: SGO [SGO000004034 digital image!], GH [GH00096302 digital image!]).

Cryptantha alfalfalis = Eritrichium rigidum Phil., Anales Univ. Chile 90: 529. 1895. Cryptantha rigida (Phil.) Reiche, Fl. Chile 5: 224. 1907. Type: Chile. [ Región Metropolitana de Santiago:] Río Colorado, Jan. 1888, R.A. Philippi s.n. (first-step lectotype, designated by Johnston 1927, pg. 61: SGO; second-step lectotype, designated here: SGO [SGO000004131 digital image!]; isolectotypes: GH [GH00096574 digital image!], SGO [SGO000004132 digital image!]).

Notes.

Rudolph A. Philippi’s (1895) description of Eritrichium alfalfalis was based on a collection he made in the valley of the Colorado River in Chile. Johnston (1927) discussed this name and its original material, stating that the “type” was lodged at SGO, although two sheets annotated in Philippi’s hand as " Eritrichium alfalfalis " are actually lodged there. The material found at SGO is in agreement with the locality and the diagnosis cited in the protologue. Thus, according to the Art. 9.17 ( Turland et al. 2018), the choice of Johnston (1927) is here interpreted as a first-step lectotypification. From among the material available for typification purposes, the sheet SGO000004033 is here selected as a second-step lectotype of the name.

The protologue of Eritrichium rigidum (Philippi, 1895) includes a direct reference to a collection made by R. A. Philippi in the valley of the Colorado River in Chile. Johnston (1927) referred to the original material of this name, stating that the “type” was lodged at SGO. However, two sheets annotated by Philippi as " Eritrichium rigidum " were found there in agreement with the protologue. Thus, Johnston’s statement is here interpreted as a first-step lectotypification. In this context, the sheet SGO000004131 is here selected as a second-step lectotype of the name
