Croton yecorensis

Croton yecorensis is a plant species endemic to a small region the State of Sonora, Mexico. The plant is known only from a mountainous region in the Sierra Madre Occidental in extreme eastern Sonora, only a few km from the line with Chihuahua. All the known populations lie within 60 km of one another in open rocky areas in pin-oak woodlands at elevations of 1200–1700 m.[1][2]
