Description
Ulmus ismaelis Todzia & Panero is a small tree discovered circa 1997 in southern Mexico by Ismael Calzada in riparian forest along the Mixteco River system in northeastern Oaxaca, where it grows among large boulders in the limestone canyons. The tree has also been found more recently in Honduras and El Salvador. The tree is exceptional in its habitat: dry places, sometimes with <500 mm precipitation, and comparatively low altitudes of 450–750 m.
