There are a couple other species of Eysenhardtia found over in Texas and more species as you head into Mexico and as far south as Guatemala. But hey, meanwhile here at home if you live in or like to hang out in Bisbee, Arizona you can find kidneywood (Eysenhardtia orthocarpa) along the sides of the road around Warren and San Jose. I’ve come across some nice shrubs on the east side of the Chiricahua Mountains in Horseshoe Canyon and come to think of it I’ve seen low browsed specimens on rocky slopes in the Peloncillos. And hello, there is always Mendoza Canyon in the Coyotes.
The two drawings of Eysenhardtia orthocarpa are by Lucretia Brazeal Hamilton (you can see her initials) from Benson and Darrow’s Trees and Shrubs of the Southwest Deserts and Sarah Kahlden Arendale from Robert Vines’ Trees, Shrubs and Woody Vines of the Southwest. There are some great photos of kidneywood to be found at SEINet as well. And now you know.
