摘要

凤仙花， A.Leu和M.L.Moody(睡莲科)来自北领地卡卡杜国家公园。这个新种是北领地“顶端”特有的，以前被包括在N. violacea Lehm中。kakaduensis的独特花型通常比N. violacea的花小，花瓣尖钝，颜色不同，这促使了对该地区分类群的遗传研究。对来自澳大利亚北部的cpDNA trnL (UAA) - trnF (GAA)基因间间隔区进行测序，并进行单倍型网络分析。在澳大利亚北部发现，具有独特花形的kakaduensis种群的植物与N. violacea在遗传上不同，它们共享4个snp，并且在cpDNA基因间隔区有一个显著的23 bp的indel，以支持形态属性和物种名称。

Nymphaea kakaduensis (Nymphaeaceae), a new species from the northern portion of the Northern Territory, Australia

Nymphaea kakaduensis C.B.Hellq., A.Leu & M.L.Moody (Nymphaeaceae) is described from Kakadu National Park, Northern Territory. This new species is endemic to the “Top End” of the Northern Territory and was formerly included in N. violacea Lehm. The distinct floral form of N. kakaduensis of having generally smaller flowers with blunt-tipped petals and different coloration than N. violacea instigated a genetic study of taxa from the region. The cpDNA trnL (UAA) - trnF (GAA) intergenic spacer region was sequenced from samples from across northern Australia and a haplotype network analysis was conducted. Plants from populations that had the distinct floral form of N. kakaduensis are found to be genetically distinct from N. violacea in northern Australia sharing 4 SNPs and a notable 23 bp indel in the cpDNA intergenic spacer region to support the morphological attributes and species designation.

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.
