Discussion
The exact location where Parry collected the type material for Emorya suaveolens is not known. The author believes that all of Parry's collections of Emorya are from one locality. Based on available collections from the area through which he traveled, the most likely locations are the canyons of Boquillas, Maravillas, or San Vincente.
In Mexico, Emorya suaveolens occurs at elevations to 2400 m.
Selected References
