Discussion:

Hedyotis lancifolia Schum. in Schum. & Thonn., Beskr. Guin. PI. 72. 1827.

Oldenlandia herbacea of auth., non Linnaeus.

Type. Tropical Africa.

Bremekamp [Verhand. kon. Neder. akad. afd. Naturk. Tweede Reeks. 48(2): 230-234. 1952] has shown that the name O. herbacea of authors, not (L.) Roxb., previously used in various floras, must be replaced by O. land folia, a species originally described from Africa and introduced into tropical South America.
