摘要

21种Grevillea目前包括澳大利亚三叶虫组感应植物区系，或组1感应Grevillea书。除横贯大陆的种麻外，所有种。分布在西澳大利亚的西南部。本文所描述的Grevillea pieroniae Olde，目前被西澳大利亚植物标本馆视为Grevillea sp. Stirling Range (D.J. McGillivray 3488 & A.S. George)。它有一些亲缘关系，通过共同拥有类似的截锥形或圆柱形花粉呈现器。绿皮菊是一种稀有物种，受到肉桂疫霉、火灾频率、干燥气候以及野生和本地食草动物的潜在威胁，因此需要仔细评估和持续监测。提供了三叶虫组的简短历史，以提供Grevillea pieroniae的背景，并作为其他相关物种的先驱，很快就会被认识到。

Grevillea pieroniae Olde (Proteaceae: Grevilleoideae: Hakeinae), a rare new species in the Triloba Group from the Stirling Range, Western Australia, and a short history of the group.

Twenty-one Grevillea species currently comprise the Triloba Group sensu Flora of Australia, or Group 1 sensu The Grevillea Book. All species except the transcontinental species G. anethifolia R.Br. are distributed in south-west Western Australia. Grevillea pieroniae Olde, herein described, is currently treated as Grevillea sp. Stirling Range (D.J. McGillivray 3488 & A.S. George) by the Western Australian Herbarium. It has some affinity with Grevillea anethifolia through shared possession of similar truncate-conical to cylindrical pollen-presenters. Grevillea pieroniae is a rare species that is potentially threatened by Phytophthora cinnamomi, fire frequency, a drying climate, as well as feral and native herbivore-grazing, so requires careful assessment and ongoing monitoring. A short history of the Triloba Group is provided to give context to Grevillea pieroniae and as precursor to other related species soon to be recognised.

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.
