Research and Conservation in Southern Sonora, Mexico

Caesalpinia platyloba (palo colorado)

Caesalpinia platyloba is a common tree in southern Sonoran tropical deciduous forest. Larger trees are difficult
to find because of overharvesting. The hard wood is valued for fenceposts, which reportedly last a century in the ground.

The yellow flowers appear in June and July, at the very end of the dry season. Leaves sprout with the rains.
