(first-step lectotype, designated by Johnston 1927 . pg. 70: SGO; second-step lectotype, designated here: SGO [SGO000004044 digital image!]; isolectotypes: GH [GH00096364 digital image!], SGO [SGO000004043 digital image!]). Notes. The protologue of Eritrichium apricum ( Philippi 1864 ) includes a direct reference to various collections made by R. A. Philippi in Aconcagua province and Catemu, Chile. Four syntypes annotated in Philippi's hand as " Eritrichium apricum " and in agreement with the diagnosis cited in the protologue are found at GH, S, and SGO. The material held at GH and SGO consists of three specimens collected in Catemu in 1860; one from among them (SGO000004035), however, has a more precise reference to the place of collection (i.e., Cajon del Boldo). On the other hand, the sheet found at S (S12-25271) comes from a collection made in Aconcagua province, Chile, without reference to the date of collection. In this context, the sheet SGO000004035 is here chosen as the lectotype. In describing Eritrichium bridgesii , Rudolph A. Philippi (1895) cited a collection he made in Lampa, Chile. Three specimens linked to the type collection are found at GH and SGO. The material kept at SGO bears original labels annotated by R. A. Philippi with the identification of " Eritrichium bridgesii " and agree with the diagnosis as referred to in the protologue. Johnston (1927) clearly indicated by direct citation that the type is housed at SGO with no further reference. In this context, Johnston's (1927) statement must thus be considered as a first-step typification since two duplicates of the gathering made by R. A. Philippi were found at SGO. In order to narrow this broad designation, the sheet SGO000004044 is here selected as a second-step lectotype (Art. 9.17 of the ICN; Turland et al. 2018 ).
