Abstract

Morphological studies of Lechenaultia filiformis R.Br. have determined that more than one taxon is presently included under that name. We here recognise the suite of disjunct populations from north-east Queensland, north-east Northern Territory, New Guinea and the Moluccas as a new species, Lechenaultia peregrina R.W.Jobson & R.L.Barrett. This is the third tropical species of Lechenaultia currently recognised, however further studies are required to assess the status of about five additional entities in the Northern Territory and Western Australia currently included in L. filiformis s.l. Seed article morphology is critical for species delimitation in tropical Lechenaultia, but seed articles are often absent from collections, or only immature, as they fall quickly once ripe.

澳洲北部、新几内亚和摩鹿加群岛的一新种

毛竹的形态学研究。已确定该名称下目前包括一个以上的分类单元。在这里，我们将来自昆士兰东北部、北领地东北部、新几内亚和摩加斯群岛的一组不相交的种群视为一个新物种，即Lechenaultia peregrina r.w. johnson和R.L.Barrett。这是目前已知的第三个热带Lechenaultia物种，但还需要进一步的研究来评估北领地和西澳大利亚目前包括在L. filiformis s.l中的另外五个实体的状态。热带Lechenaultia的种子形态对物种划分至关重要，但种子通常在收集中缺失，或者只是未成熟，因为它们一旦成熟就会迅速脱落。

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.
