Región de Atacama: Caldera, Sep. 1885, F. Philippi s.n. (first-step lectotype, designated by Johnston 1927, pg. 43: SGO; second-step lectotype, designated here: SGO [SGO000004070 digital image!]; isolectotypes: GH [GH00096373 digital image!], SGO [SGO000004071 digital image!]).

Notes.

In describing Eritrichium chaetocalyx , Rudolph A. Philippi (1860) cited a gathering he made near Pan de Azúcar, Chile. Two duplicates of the type collection in agreement with the protologue and annotated by him as " Eritrichium chaetocalyx " were located at SGO. Johnston (1927) discussed this name and its original material, referring to a sheet lodged at SGO as the “type” of the name. In this context, Johnston’s (1927) statement must thus be considered as a first-step typification. Thus, in order to narrow this designation, the sheet SGO000004073 is here selected as a second-step lectotype.

In the protologue of Eritrichium divaricatum , Rudolph A. Philippi (1895) cited as type material a collection made by F. Philippi in Caldera, Chile. Johnston (1927) referred to a specimen kept at SGO as the “type” of the name, although two sheets annotated, in R. A. Philippi’s hand, as " Eritrichium divaricatum " are found there. This situation determines that Johnston’s (1927) statement must be considered as a first-step lectotypification. In this context, the duplicate SGO000004070 is here selected as a second-step lectotype (Art. 9.17 of the ICN; Turland et al. 2018).

Rudolph A. Philippi (1895) described Eritrichium pustulosum based on a specimen he collected in Caldera, Chile. According to Johnston (1927), the type material of the name is lodged at SGO. However, three sheets linked to E. pustulosum , in agreement with the protologue, were located at SGO, which can certainly be considered as original material. In this context, Johnston’s (1927) statement must be considered as a first-step lectotypification. In order to narrow this earlier designation, the sheet SGO000004125 is here selected as a second-step lectotype.
