3. Commelina diffusa Burm. f. (Trop.) – An exceptional and ephemeral soybean alien, recorded only once in the port of Antwerpen in 1997 (Verloove & Vandenberghe 1998).
Commelina diffusa much resembles C. communis and they are hardly distinguishable in the absence of flowers (although the former usually has slightly shorter and narrower leaves).
