TYPICAL WILD FORM OF THE TREE DAHLIA 
It is in this form—a tall plant producing lilac-pink single flowers—that Dahlia maxoni occurs in 
the highlands of Guatemala. When brought into cultivation it gives rise to double-flowered 
varieties of several shades of color. The stem here shown was cut and photographed by the 
roadside on the slopes of the Volcan de Agua, near Antigua, Guatemala. (Fig. 20.)
