Linnaea 34 (1): 46 (Müller Argoviensis 1865).
We only know the type collection of this species (Herb. Pavón s.n.; G-DC[G00324653] and G[G00383632]). The labels of these specimens indicate as origin “In Peruvia” as also appears in the protologue, but probably they do not come from Peru but from Mexico (Cardiel et al. 2013b). This plant seems morphologically very close to some Mexican species, still little known.
