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.
