Crossosomataceae is a small plant family, consisting of four genera of shrubs found only in the dry parts of the American southwest and Mexico.

[3][4][5][6] Crossosoma are shrub-like plants which can vary from being 50 cm to 5 meters tall, with small alternating leaves that surround the stem, or leaves clustered in small spurts (fascicles).

[7] Apacheria, however, has opposite leaves.

[3] Crossosoma has usually white flowers that are generally bisexual and have 5 petals attached to a nectary disk,[7] but in Velascoa the flowers are campanulate and have an extremely reduced nectary disk.
