The plant is endemic to California, where it is known only from the slopes of the Sierra Nevada in Tuolumne and Calaveras Counties. [4] [5] [6]
Allium tribracteatum is a small onion plant producing a stem only a few centimeters long from an oval-shaped bulb. There are two leaves which are usually much longer than the stem. The inflorescence contains up to 30 petite white to purple flowers, each less than a centimeter long. Tepals are white to pink with red or purple midveins; anthers purple; pollen gray.
