摘要

新红豆杉属（Neomicrocalamus）和红豆杉属（Temochloa）是关系密切的属，对它们的 "花序 "结构了解不全面，也难以协调。在重新研究了花序形态之后，这两个属的所谓 "小穗 "应被认为是假小穗，其腋芽大多不活跃。新的竹类群包括一个新种的两个变种，被归入 Temochloa 属，代表了中国和越南的新属记录。

Temochloa (Poaceae, Bambusoideae), a newly-recorded bamboo genus for China and Vietnam, with new taxa and a re-interpretation of flowering structures.

Neomicrocalamus and Temochloa are closely-related genera for which 'inflorescence' structures were incompletely understood and difficult to reconcile. After re-examining the inflorescence morphology, the so-called 'spikelets' of both genera as described should instead be recognised as pseudospikelets with mostly inactive axillary buds. The new bamboo taxa, comprising two varieties of a new species, are placed in Temochloa, representing a new genus record for China and Vietnam.
