Other info. - This species can be found throughout Missouri and is quite common. It can be identified in the field by its reddish stems, milky sap, opposite leaves, and small white flowers.
A. cannabinum is used as "Hemp", made from the twisted fibers of the plant. The species epithet means "Hemplike". Traditionally the plant was also used to treat a variety of ailments. The sap of the plant contains cardiac glycosides and is toxic in moderate to large doses. Some of the secondary compounds of the plant have shown antitumor activity.
Steyermark divides the species into two varieties. Variety cannabinum (pictured above) is basically glabrous throughout the entire plant. Variety pubescens exhibits pubescence on the leaves, stems, and calyx. Both are common.
