Tinantia is a genus of plants in the Commelinaceae, first described in 1839. They are commonly called widow's tears or false dayflowers due to their resemblance of the closely related true dayflowers of the genus Commelina. Tinantia is native to North and South America from Texas + Hispaniola to Argentina, with a center of diversity from Mexico to Nicaragua.Kew World Checklist of Selected Plant FamiliesDavidse, G., M.
