Allium rhizomatum is a species of plant native to southern Arizona (Cochise and Santa Cruz Counties), southern New Mexico (Catron, Grant, Hidalgo, Socorro, Sierra and Eddy Counties) and western Texas (Brewster and Jeff Davis Counties) in the United States, and Chihuahua in Mexico. It is generally found in dry, grassy areas at elevations of 1200–2200 m.^[1]^[2] Its common names include spreading wild onion^[3] and red flower onion.^[4]

Arizona is a state in the southwestern region of the United States. It is also part of the Western and the Mountain states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona shares the Four Corners region with Utah, Colorado, and New Mexico; its other neighboring states are Nevada and California to the west and the Mexican states of Sonora and Baja California to the south and southwest.

Cochise County is located in the southeastern corner of the U.S. state of Arizona. The population was 131,346 at the 2010 census. The county seat is Bisbee.

Santa Cruz is a county in southern Arizona. As of the 2010 census, its population is 47,420. The county seat is Nogales. The county was established in 1899. It borders Pima County to the north and west, Cochise County to the east, and the Mexican state of Sonora to the south.

Allium rhizomatum spreads by means of underground rhizomes, with new bulbs forming as much as 3 cm away from the parent plant. Bulbs are narrowly ellipsoid, up to 3 cm long but rarely more than 1 cm across. Flowers are up to 10 mm across; tepals white with red central veins, without glands; ovary oblong to elongate, lacking a crest; anthers yellow or pink; pollen yellow or white.^[1]^[5]^[6]^[3]

In botany and dendrology, a rhizome is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards.

Ellipsoid closed quadric surface that is a three dimensional analogue of an ellipse

An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation.

In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus.

Some authors have considered A. rhizomatum to be the same species as A. glandulosum found in central and southern Mexico, but this latter species has deep red flowers, a rounded ovary and glands on the sepals.^[1]
