Discussion | The names Abronia cycloptera A. Gray and Tripterocalyx cyclopterus (A. Gray) Standley are illegitimate, based on an attempt by Gray to rename A. micrantha Torrey. Gray believed A. micrantha to be a “precociously fertilized state” of what is here recognized at T. carneus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
