Xochiquetzallia

Xochiquetzallia is a genus of geophytic flowering plants of the subfamily Brodiaeoideae in the family Asparagaceae. The genus contains four species: three previously classified within the genus Dandya and one other previously classified within Milla. Earlier genetic and morphological research had shown that the broad Milla clade of plants is made up of two sister lineages. The four plant species now within Xochiquetzallia make up one of these lineages, and are more closely related to each other than they are to the second lineage, which is made up of the remaining Milla species, Dandya purpusii, and the genera Behria, Bessera, Jaimehintonia and Petronymphe. Jorge Gutiérrez and Teresa Terrazas, two of the botanists who worked on the earlier research, followed up in 2020 with a paper formally transferring the four species from Dandya and Milla to Xochiquetzallia. All four Xochiquetzallia species occur in Mexico's Río Balsas watershed, south of Mexico City....read more on Wikipedia.
