Maclurochloa tonkinensis sp. nov. (Poaceae: Bambusoideae) from Vietnam

Abstract

Maclurochloa K. M. Wong (Gramineae: Bambusoideae) is a genus of clambering bamboos with dry caryopses. It was thought to be monotypic in Peninsular Malaysia, but here we report one more species from Vietnam which is new to science: Maclurochloa tonkinensis H. N. Nguyen et V. T. Tran sp. nov. Maclurochloa tonkinensis is most similar to M. montana (Ridl.) K. M. Wong from which differs mainly by having internodes 50–58 × 3.0–3.5 cm and culm leaves with auriculate sheaths and erect blade.

“…Maclurochloa K. M. Wong (), one of the clambering bamboo genera in the subtribe Bambusinae , of Poaceae was separated from Dinochloa Buse (1854) to accommodate the single species, Maclurochloa montana (Ridley) K. M. Wong described from Malaysia (Wong ). Today, three species are recognized in the genus, and these are distributed in Malaysia and Vietnam (Wong , Nguyen and Tran , 2014). In Vietnam, two species have been recorded (Nguyen and Tran , 2014), viz.…”
