Validating Latin diagnosis: that of "Carex chlorostachys var. conferta" (L. K. Dai in L. K. Dai & S. Yun Liang, Fl. Reipubl. Popularis Sin. 12: 526. 2000).

This name was not validly published by L. K. Dai in 2000 because the herbarium in which the type is conserved was not specified (Vienna Code, Art. 37.7). For the same reason, it was not validated by S. Y. Jin and Y. L. Chen (Cat. Type Spec. Herb. China (Suppl. II), 75. 2007).
