This is a rare species known only to Dinotopia, related to the common burdock genus of the Old and New Worlds. Deep-rooted, and growing to a height of three to six feet, it bears purple flowers with hooked bristles. Tinctures of the flowers are used in medicinal healing, especially to promote strong wing membranes among the pterosaurs.
The root is gathered, dried, and prepared in a tea-like infusion, using waters of the springs near Bent Root, and offered to humans after they have reached twenty-four summers. The claim often made is that the tea changes the body’s chemistry to reverse the ageing process. Thus a human can approach or even exceed the long lifespans of the dinosaurs, known to live beyond their 250th year.
