This species is very similar to the Spreading Dogbane. The five-pointed, tubular flowers, however, are very small and greenish white and are borne erect in terminal clusters. The plant is somewhat less scrawly and grows from about one to four feet in height from a deep, vertical root. It is found in gravelly or sandy soils, chiefly near streams, and varies greatly. It flowers from June to August. The tip of the long, oval leaf is very sharply pointed, and the juice is milky and sticky. The tough-fibred stalks offer a substitute for hemp, and were employed by the Indians fo making twine, fish nets, baskets and kindred articles. The root is used in medicine to some extent. Indian Hemp is found in fields and thickets from Florida and lower California, northward into the British Possessions.
