Hello, I am looking for keys, descriptions, or anything that may help me with the identification of this plant. It might be in the Sterculiaceae family and is 40 ft tall, leaves 9-10 cm long. It was collected in Southern Arizona. The following leaf image is all I have to go on: http://www.csdl.tamu.edu/FLORA/Eddy/unknown.gif Thank you, Eddy Dawson
