Abstract

A new species from Guangdong, China with an unusual inflorescence is described here. is vegetatively most similar to . It can be distinguished from all species within morphologically by its unique zigzag monochasial cyme and infructescence. To confirm the phylogenetic relationships and generic placement of this species, not only morphological anatomical features but also chromosome and DNA sequence data were examined and analysed here. Two samples from different populations identified as are monophyletic and were nested in a monophyletic clade within with high branch support. The somatic chromosome number of the new species is also reported (2 = 36), supporting its placement in the genus.

摘要

本文描述了一种来自中国广东的新物种，其具有独特的花序。在营养体方面，它与[某物种]最为相似。通过其独特的之字形单歧聚伞花序和果序，它在形态上可与[某属]内的所有物种区分开来。为了确定该物种的系统发育关系和属的归属，不仅对其形态解剖特征进行了研究分析，还检测分析了染色体和DNA序列数据。来自不同种群的两个被鉴定为[该物种]的样本是单系的，并以高分支支持率嵌套在[某属]内的一个单系分支中。还报道了该新物种的体细胞染色体数（2n = 36），支持其归入该属。
