Monoptilon bellioides

It is native to stony and sandy plains in the Mojave Desert of California and the Sonoran Deserts of the Southwestern United States northwestern Mexico. It is and is very common in the northern, eastern, and southern parts of the desert.

Monoptilon bellioides is a short annual plant; in seasons with very little rainfall, the plant may only grow to 1–2 cm, if it grows at all, while in seasons of heavy rainfall, it can grow up to 25 cm tall. The leaves are linear, 5–10 mm long, with a blunt apex.

The flowers are produced in dense inflorescences (capitula), 2 cm diameter, with white ray florets and yellow disc florets in the center. The flowers open in the morning and close in the evening.
