INDIAN HEMP (Apocynum cannobinum), a North Amer ican plant of the dog-bane family (Apocynaceae), native to fields and thickets from Quebec to British Columbia and southward to Florida and Lower California. It is an erect, often much branched perennial, I to 4 ft. high, with smooth, oblong, opposite leaves, and small, clustered, greenish-white flowers, from each of which develops two very narrow fruit-pods (follicles), about 4 in. long, containing numerous downy-tufted seeds. The tough bast fibres of the inner bark were utilized by the Indians for cordage. The variety of hemp yielding hashish is also called Indian hemp.
