Abstract

Pycnolejeunea glauca, originally described by Stephani based on a collection in New Zealand by William Colenso, was placed by Grolle into the synonymy of the paleotropical species Cheilolejeunea intertexta with a type from Micronesia. In this study, we generated DNA sequences from a recently-collected sample of P. glauca and compared them with published sequences of C. intertexta from China. Pycnolejeunea glauca was recovered in the phylogenetic analyses as sister to C. nipponica, whereas C. intertexta grouped in another clade with C. vittata and C. streimannii. The analysis justifies the reinstatement of P. glauca as the new combination Cheilolejeunea glauca, a New Zealand endemic. Descriptions and illustrations are provided of key features of this species together with data on its position in the phylogeny of the genus.

DNA测序支持从Cheilolejeunea intertexta的同义词(Cheilolejeunea glauca梳子)恢复Pycnolejeunea glauca。11 .(龙葵科，龙葵科)

Pycnolejeunea glauca最初由Stephani根据William Colenso在新西兰收集的标本描述，由Grolle将其归入具有密克罗尼西亚类型的古热带物种Cheilolejeunea intertexta的同义词。在这项研究中，我们从最近收集的P. glauca样本中生成了DNA序列，并将其与中国发表的C. intertexta序列进行了比较。Pycnolejeunea glauca是C. nipponica的姐妹，而C. intertexta则与C. vittata和C. streimannii归为另一个分支。这一分析证明了恢复青光眼P. glauca为新西兰特有的新组合Cheilolejeunea glauca是合理的。描述和插图提供了该物种的主要特征，以及其在该属系统发育中的位置数据。

期刊介绍： Manuscripts submitted for publication in TELOPEA are published online, after peer review and acceptance by the TELOPEA Editorial Committee and when final editorial formatting has been completed. The journal specialises in plant systematics and phylogeny. The geographic scope of the journal encompasses Australia, Malesia, Melanesia, Micronesia, and Polynesia. The suitability of a work for the journal depends on the topic and the region of origin, generally the narrower the focus of the manuscript the closer to New South Wales must be its geographic focus. As a general guide, we will consider: 1) revisionary treatments and other substantial bodies of work from any of the regions mentioned above. 2) new species from any Australian state. 3) new country records for Australia from any state. 4) new state records from New South Wales only. However, we aim to support botanical research across the broader Australasian and Pacific region, and will consider submissions on their merit. Generally we will not consider extraterritorial new country records, or single lectotypification papers unless they pertain to New South Wales taxa, or have significant bearing on the Australian flora.
