Plant and Fungal Species Descriptions

A general introduction to Zingiber is provided, along with an outline of the materials and methods used in this paper and which are to be used in our subsequent taxonomic studies on Zingiber in China. Based on an investigation of the protologues, and on comparisons of both the type specimens and living materials collected from the type localities and their immediate vicinities, Zingiber stipitatum S.Q.Tong and Z. menghaiense S.Q.Tong are here reduced to synonymy under Z. kerrii Craib. A previous lectotypification of Zingiber kerrii is discussed and amended. The existence of mixed collections among the isotypes of Zingiber stipitatum is highlighted and a proposal to exclude the vegetative parts belonging to Z. neotruncatum from the type material is made. A description and a colour plate of Zingiber kerrii based on a collection from China are provided.
