Taxonomy
It was described as Rhodophiala laeta Phil. by Rodolfo Amando Philippi in 1860.[6][2] A new genus Eremolirion Nic.García was described by Nicolás García Berguecio in 2019,[5] but due to confusion with the similarly named Eremiolirion J.C.Manning & F.Forest (Tecophilaeaceae), a new genus Paposoa Nic.García and species Paposoa laeta (Phil.) Nic.García was required and published by García in 2020.[7] Within the tribe Hippeastreae, it is placed in the subtribe Traubiinae.[8]
Etymology
The generic name Paposoa refers to Paposo, Chile.[9] The specific epithet laeta means bright,[10]
