During the preparation of the treatment of the family Boraginaceae s. str. for Argentina, dozens of names were identified as needing typifications to stabilize their nomenclature. As a result, lectotypes are designated for 11 names (Allocarya alternifolia Brand, Amsinckia angustifolia Lehm. var. microcarpa Speg., Amsinckia tessellata A. Gray, Echinospermum patagonicum Speg., Eritrichium albiflorum Griseb., Eritrichium humile (Ruiz & Pav.) DC. var. capillatum Clos, Eritrichium humile (Ruiz & Pav.) DC. var. congestum Wedd., Gruvelia pusilla A. DC., Lithospermum chilense Colla, Myosotis corymbosa Ruiz & Pav., and Pectocarya chilensis DC.). Additionally, second-step lectotypes are designated for nine names in Eritrichium Schrad. ex Gaudin (E. calandrinioides Phil., E. cinereum Phil., E. flavicans Phil., E. germainii Phil., E. graminifolium Phil., E. pedicellare Phil., E. pratense Phil., E. pugae Phil., and E. pulchellum Phil.).
