Rohdea wangiana (Asparagaceae), a new species from southwestern Sichuan, China

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.
