Comment:Jones cites the authorship of this designation as "M. Clements" and states that "This is a new name for the taxon previously known as P. macrostachyum var. ringens (H. G. Reichb.) A. S. George.". However, there is no full and direct reference to the intended replaced synonym as required by ICN Art. 41.5 (Shenzhen Code, 2018).
