HT: Oersted s.n.; 1845-1848; Costa Rica: San José: Volcán Irazú According to Breedlove et al., Ann. Missouri Bot. Gard. 69: 228 (1982): "Oersted, who collected in Costa Rica and Nicaragua from 1845 to 1848, and F. Liebmann, who collected in Mexico from 1840 to 1842, collaborated jointly on their collections upon their return to Europe. Léveillé mistook the type for a Liebmann collection, hence the specific epithet and the locality cited in the protologue as "Mexique: mont Frasu" (=Irazú)."
