Its leaves measure 2.5 to 9 cm long and 1.5 to 3.5 cm wide, and each leaf is attached to the stem by a petiole 0.5 to 2.5 cm in length. This species has been recorded in the United States (Arizona, Colorado, New Mexico, Oklahoma, Texas), Mexico, Guatemala, and Panama. It usually grows along streams or other wet locations, at elevations between 900 and 2000 metres above sea level.
