Commelina

Genus of flowering plants

Commelina is a genus of approximately 208 species commonly called dayflowers due to the short lives of their flowers, and less often known as widow's tears. It is by far the largest genus of its family, Commelinaceae. The Swedish taxonomist Carl Linnaeus of the 18th century named the genus after the two Dutch botanists Jan Commelijn and his nephew Caspar, each representing one of the showy petals of Commelina communis.
