摘要

两种已确认的新拉杜拉-荷兰拉杜拉属地理谱系的研究。已经发现了来自昆士兰湿热带地区的个体和来自新南威尔士的个体之间的形态差异。来自湿热带的个体成熟时花被较短(1.6-2.0毫米或3.8-4.4毫米)，叶裂片通常有许多边缘的芽，叶小叶更小，更方。形态学上的差异，特别是花被长度上的差异，以前没有被充分认识到，这为昆士兰湿热带谱系作为一个独特的新种提供了证据，这里描述的是Radula tonitrua。tonitrua和R. novae-hollandiae之间的系统发育分化程度和固定的分子差异与R. ocellata和R. pulchella之间的分离相当，后者是另一对具有相同地理分离的物种。

Contribution to the bryoflora of Australia, V. Radula tonitrua sp. nov. from Queensland

Study of two recognised geographic lineages within Radula novae-hollandiae sens. lat. have resulted in the detection of morphological differences between individuals from the Queensland Wet Tropics, and those from New South Wales. Individuals from the Wet Tropics have perianths that are shorter at maturity (1.6–2.0 v. 3.8–4.4 mm), leaf lobes that usually bear numerous marginal gemmae, and leaf-lobules that are smaller and more quadrate. The morphological differences, particularly in perianth length, were not fully appreciated previously and provide evidence supporting the recognition of the Queensland Wet Tropics lineage as a distinct and new species, Radula tonitrua, which is here described. The degree of phylogenetic divergence and fixed molecular difference between R. tonitrua and R. novae-hollandiae, are comparable with the separation observed between R. ocellata and R. pulchella, another species pair exhibiting the same geographic disjunction.

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.
