Abstract
Rohdea wangiana is described as a new species from SW Sichuan, China. It is somewhat similar to R. pachynema in based on spikes without a marked terminal tuft of sterile bracts and deltoid filaments, but differs based on a combination of the following characters: leaf blades marginally serrulate; peduncle ebracteate; one bract per flower; perianth externally angulate, perianth segments distally denticulate or three-lobed, small lobe present between adjacent filaments, filaments inserted to base of perianth segments; stigma obviously lower than stamens; lack of slender stolons.

Rohdea wangiana H. Z. Feng & Z. Qiang Lu, sp. nov. 

Diagnosis: The new species resembles R. pachynema, but differs based on absence of slender stolons, the leaf blade with serrate margin, one bract per flower, peduncle ebracteate, with protuberance between two filaments and the positions of filaments and stigma in the perianth tube.
