Abstract

Globba zwegabinensis sp. nov., under sect. Haplanthera (Zingiberaceae) is newly described and illustrated from the Zwegabin Mountain of Kayin State in southern Myanmar. G. zwegabinensis is morphologically allied to G. sessiliflora and G. lithophila but differs in having the leaves with a foetid smell, glabrous blade, completely yellow filament, glabrous ovary, larger cuneiform labellum with bifid apex, glabrous and oblong to ovate fruit, lack of bulbils and anther appendages. A description and photographic data, along with the comparative characteristics of the closely allied species, are provided.

Keywords: Zingiberaceae; New taxon; Myanmar, Zwegabin Mountain.

Globba zwegabinensis Latt, M.K.Naing & Joongku Lee, sp. nov. 

Diagnosis: Globba zwegabinensis is morphologically similar to G. sessiliflora Sims under the same sect. Haplanthera and G. macrochila Sangvir. & M.F. Newman under sect. Nudae but can be distinguished by glabrous leaf-blade, the foetid smell of leaf, totally yellow filament, glabrous ovary, larger cuneiform labellum with bifid apex, glabrous and oblong to ovate fruit, and lack of bulbils. 

Etymology. The species epithet is named after the type locality Zwegabin Mountain, where this species was specifically found among the aggregated limestone hills and mountains across Pha-an Township.

Vernacular name: “Zwe-gabin Badein-ngo ဇွဲကပင်ပန်းထိမ်ငို” (proposed here). “Badein-ngo” and “Badein-ma-naing”are the local names of Globba species in Myanmar, whereas “Zwegabin” refers to the name of the mountain where it was found first.
