8. Commelina schomburgkiana var. brasiliensis Seubert (1855: 262)

Lectotype (designated here): — BRAZIL. Bahia: C. F. P. von Martius s.n. (M-0274948! [ Fig. 9 ]).

= 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. schomburgkiana var. brasiliensis provides the following information: “pedicello interiore abortivo, exteriore 1–2-floro” and “ in interioribus prov. Bahiensis leg. Martius ”. I was able to trace one sheet at M that can be considered original material for this name. Therefore, I designate here the specimen on this sheet (M-0274948— Fig. 9 ) as lectotype of the name C. schomburgkiana var. brasiliensis . Study of the specimen confirms that this name is a synonym of C. diffusa .
