摘要

本文重新评价了法属波利尼西亚南岛拉帕伊提岛苏科植物的分类现状和分布。这包括鲜为人知的Machaerina involuta H.St John (Cyperaceae, Schoeneae部落)，在它第一次被收集86年后。详细的形态学检查表明，该植物属于莫雷罗亚属。而新的组合，莫雷罗蒂亚(H.St John) j.j.b bruhl & r.l.b雷特(Morelotia involuta)就是在这里生产的。据报道，Rapa Iti有苏柏科19种(占维管植物区系的10%)。苏科植物的高度多样性引起了对拉帕伊蒂的生物地理联系和环境条件的进一步讨论，并进行了总结。新命名的柏科植物(Carex rapaensis (H.St John) K.L.Wilson, Carex stokesii F.Br)。， C.斯托克思;， rapensis F.Br。[j]; [c]; [c];，加尼娅·斯托克西f·br。和Rhynchospora stokesii F.Br)提出，并注意到目前尚未确定的Carex。

Reassessment of the taxonomic status of Cyperaceae on Rapa Iti, Austral Islands, French Polynesia, with a new combination, Morelotia involuta

We reassess the current taxonomic status and distribution of Cyperaceae on Rapa Iti, Austral Islands, French Polynesia. This includes the poorly known Machaerina involuta H.St John (Cyperaceae, tribe Schoeneae), 86 years after it was first collected. Detailed morphological examination revealed that M. involuta belongs in Morelotia Gaudich., and the new combination, Morelotia involuta (H.St John) J.J.Bruhl & R.L.Barrett, is made here. Nineteen species of Cyperaceae are reported for Rapa Iti (10% of the vascular flora). The high diversity of Cyperaceae invites further discussion of the biogeographic connections and environmental conditions of Rapa Iti and a summary is provided. Notes on additional Cyperaceae named from Rapa Iti (Carex rapaensis (H.St John) K.L.Wilson, Carex stokesii F.Br., C. stokesii var. aristata F.Br., Cyperus rapensis F.Br., Eleocharis caribaea var. stokesii F.Br., Gahnia stokesii F.Br. and Rhynchospora stokesii F.Br.) are presented and a presently unidentified Carex is noted.

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.
