1. Commelina agraria var. repens Seubert (1855: 261)

Lectotype (designated here): — BRAZIL. Amazonas: C. F. P. von Martius s.n. (M-0274950! [ Fig. 1 ]).

= Commelina diffusa Burman (1768: 18 , tab. 7[2]), syn. nov.

Lectotype (designated by Hunt 1994: 172):— INDIA. Coromandel, D. Outgaerden s.n. (G-00360106!).

Notes: —The protologue of C. agraria var. repens provides the following information: “statura depressa, caule repente, foliis parvis subcordato-ovatis” and “ in pratis udiusculis ad oppidulum Ega prov. Rio Negro [...] Mart. [Martius]”. I was able to trace three sheets at M (M-0274950, M-0274951 and M-0274956) that contain original specimens for this name. I here designate one of them, M-0274950 ( Fig. 1 ) as the lectotype of C. agraria var. repens . The study of the type confirms that this name is a synonym of C. diffusa .
