The name Fimbristylis complanata var. kraussiana (Hochstetter ex Steudel) C. B. Clarke was used by Tang and F. T. Wang (Fl. Reipubl. Popularis Sin. 11: 81. 1961), but the type of the basionym, F. kraussiana Hochstetter ex Steudel, belongs to F. consanguinea Kunth, which does not occur in China. T. Koyama proposed the new name F. complanata f. exaltata based on a different type. Because of the morphological differences and the more northern distribution, we are raising this form to a variety.
