Kidneywood
Eysenhardtia orthocarpa

Several leaflets of this kidneywood leaf are swollen and purple-back due to gall-causing arthropods inside. They could be mites, minute flies or perhaps gall wasps.

low. Dark brown scaly bark.
UNARMED: Unlike many leguminous woody plants of Arizona, this one is without
thorns.
FLOWERS: Spikes of small, usually white, pea flowers. Attractive to bees and butterflies.

RANGE: In Arizona this plant is found in just a few of the sycamore-lined canyons and adjacent slopes
of the southeastern mountains. It ranges into New Mexico and Mexico.
