Allium plummerae

Allium plummerae is a species of plant native to southern Arizona (Pima and Cochise Counties) in the United States and to Sonora in Mexico.[1] It is known by the common names Plummer's onion and Tanner's Canyon onion.[1] It grows on rocky slopes and stream banks in mountains regions at elevations of 1600–2800 m.[2][3][4]

Allium plummerae produces elongate bulbs up to 5 cm long but rarely more than 1.5 cm in diameter. Flowers are up to 10 mm across; tepals white or pink; anthers purple; pollen yellow.[2][5][6]

The epithet "plummerae" is in honor of one member of the expedition that collected those specimens, botanist Sara Plummer Lemmon.[5]
