Mesquite

Both peoples lived off deer, small game, rodents, and even insects, but their main food sources were probably plants such as prickly pear cactus, mesquite beans, and pecan.

Between these canyons the river has a low but rather narrow flood plain, with cottonwood groves scattered here and there, and a chaparral of mesquite bearing beans and thorns.

[…] and no botanist could for a moment fail to recognize this fact, especially as just beyond its banks there is growing on every hand the mesquite, the everywhere-present species of the Lower Sonoran zone.

Tucson is situated in beautiful mesquite riverbed country, overlooked by the snowy Catalina range.

Southward and in the very center of the plain is La Mesa, hidden in the mesquite and with splendid, typically dug, wells.
