Ekrixanthera ehecatli is a species of extinct plant first described from fossilised flowers from Mexican amber.

Its flowers lack pedicels and are pentamerous and staminate; they have a pistillode with reduced pilosity; glabrous heteromorphic tepals with truncate tips.

Additionally, the latter characters added to the pentamerous flowers separate the two fossil species from extant genera.

Its floral structures indicate an explosive manner of pollen release as well as anemophily.

[2] The name first appeared in a publication in 2016, but was not validly published under the International Code of Nomenclature for algae, fungi, and plants.
