Photographed at White Canyon Wilderness, Pinal Co., Arizona. March 2014. The identification of this plant had me and several of my colleagues stumped until Liz Makings helped.

LEAVES: Small, but very distinctive leaves are frequently divided into two lobes.

ANNUAL: Frail, herbaceous spring plant growing prostrate as a many-branched, loose mat in gravelly soil.

FLOWERS: Very small, inconspicuous greenish white flowers are in the leaf axils.

FRUIT: Very small, single seeded fruits are three-sided like other buckwheats.

RANGE: Grows obscured in the shade beneath shrubs as in upper Sonoran Desert, chaparral or juniper woods. Might be more common than thought because it hard to see.


Polygonaceae -- Buckwheat Family
