Dracaena angolensis

Dracaena angolensis, synonym Sansevieria cylindrica, also known as the cylindrical snake plant, African spear or spear sansevieria or in Brazil Saint Bárbara sword, is a succulent plant native to Angola. Formerly in the genus Sansevieria, it is now included in Dracaena.

Dracaena angolensis has striped, elongate, smooth, greenish-gray subcylindrical leaves. They are up to 3 cm (1 in) diameter and grow up to 2 m (7 ft) above soil. The spear sansevieria grows fan-shaped, with its stiff leaves growing from a basal rosette.

The species is interesting in having subcylindrical instead of strap-shaped leaves caused by a failure to express genes which would cause the cylindrical bud to differentiate dorsoventrally or produce a distinctive and familiar top and bottom surface to the leaf blade. The 3 cm (1 in) greenish-white tubular flowers are tinged with pink.
