Abronia macrocarpa is a rare species of flowering plant known by the common name largefruit sand verbena.

Abronia macrocarpa is a perennial herb with a hairy, glandular stem growing up to half a meter tall.

[5] Threats to this endangered species include habitat loss as its range is consumed for development and oil exploration.

[2][3] The habitat is also damaged by off-road vehicles, people on foot and on horseback, fire suppression activity, and the invasion of non-native species such as bermudagrass and weeping lovegrass (Eragrostis curvula).

[5] It is pollinated by sphinx moths and disperses its fruit in the summer months, at which point the plants die back and re-emerge in the fall.
