Gigantochloa glabrata (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China.

Gigantochloa glabrata N. H. Xia & Y. Zeng ex D. Z. Li & Z. C. Xu, sp. nov., a new species of paleotropical woody bamboo has been described and illustrated from Yunnan, China. The new species is morphologically similar to G. albociliata and G. levis, but differs from them by having erect culm sheath blades; culm sheath ligules 4-6 mm high, truncate, denticulate; and with a ring of white tomentum on the intranode and below the node. The new species was mistakenly identified as Gigantochloa albociliata in the Flora of China and was recognised with description of the vegetative characters in 2014, but it was not effectively published. Here, we designate a complete specimen with inflorescence as the type and describe it in accordance with the Code. [ABSTRACT FROM AUTHOR]
