Flowers of wild Tepary Bean (Phaeseolus acutifolius var. tenuifolius) are small; generally smaller than a dime, and spaced relatively far apart on the thin vine. The plant is easily overlooked, even when blooming. The fruits are (you guessed it) pods.
You can get cultivated seed varieties from Native Seeds if you want to grow these in the desert. They also sell bags of these (and other) beans to cook and eat. Yum.
