Cryptantha dichita (Phil.) I.M. Johnst., Contr. Gray Herb. 78: 35. 1927. Cryptantha dichita ≡ Eritrichium dichita Phil., Anales Univ. Chile 90: 516. 1895. Type: Chile. [Unknown region:] Desierto de Atacama, 1877, A. Villanueva s.n . (first-step lectotype, designated by Johnston 1927 , pg. 35: SGO; second-step lectotype, designated here: SGO [SGO000004062 image!; isolectotypes: GH [GH00096381 digital image!], SGO [SGO000004063 digital image!]). Note. In describing Eritrichium dichita , Rudolph A. Philippi (1895) cited eight specimens received from Augusto Villanueva from the Atacama Desert, Chile. However, only two specimens are currently lodged at SGO, where R. A. Philippi worked ( Stafleu and Cowan 1983 ). Both specimens are annotated, in Philippi's hand, as " Eritrichium dichita " and in agreement with the diagnosis found in the protologue. Johnston (1927) referred to a sheet housed at SGO as the "type" of the species name, although Philippi did not indicate any material as such at the time he published the species. Thus, Johnston's (1927) statement must be considered as a first-step lectotypification. In order to narrow this broad designation, the specimen SGO000004062 is here selected as a second-step lectotype.
