  H. N. Nguyen & V. T. Tran  DOI: 10.1111/njb.01048

A clambering bamboo endemic to the Lam Vien plateau, southern Vietnam and representing a new monotypic endemic genusYersinochloa H. N. Nguyen & V. T. Tran (Gramineae–Bambusoideae–Bambusinae), is described and illustrated. It has an indeterminate inflorescence, terminate leafy branches, pseudo-spikelets with only one perfect floret, unkeeled palea, three lodicules, six stamens with free filaments, anther apices with tiny spines, glabrous ovary with a long style, 3 plumose stigmas, and an oblong caryopsis with a relatively thin pericarp.


  


Hoang Nghia Nguyen and Van Tien Tran. 2016. Yersinochloa gen. nov. (Gramineae: Bambusoideae-Bambusineae) endemic to the Lam Vien Plateau, southern Vietnam. Nordic Journal of Botany.   DOI: 10.1111/njb.01048

In this new paper, the new genus Yersinochloa (Poaceae, Bambusoideae) is proposed to accommodate the new species Yersinochloa dalata found in southern Vietnam. The new genus is warranted by a unique combination of floral characters, i.e. an indeterminate inflorescence, terminate leafy branches, pseudo-spikelets with only one perfect floret, unkeeled palea, three lodicules, six stamens with free filaments, anther apices with tiny spines, glabrous ovary with a long style, 3 plumose stigmas, and an oblong caryopsis with a relatively thin pericarp. A comprehensive overview of the diagnostic characters of the genera Yersinochloa, Cochinchinochloa, Maclurochloa, Soejatmia, Neololeba and Mullerochloa is also provided.
