...The genus Di (two) morphe (shape) theca (wrap) is derived from the fact that the tubular flowers have wings, while the ray flowers are rod-shaped.

There are about 70 species in this genus in South Africa, and the flowers are similar to Dimorphotheca, with white or purple ray flowers, but the seeds are not winged. *Some of the terminology that refers to the genus "Osteospermum" is listed below.
