Abstract

Utricularia section Oligocista A.DC. (Lentibulariaceae) is distributed across the old and new world tropics. Wepresent a molecular phylogeny using a matrix of the nuclear ITS and two chloroplast markers that includes 19of the 37 recognised species sampled across the range of each species. The phylogenetic study also includesmembers of the closely allied sections Enskide (Raf.) P.Taylor (including section Minutae Lowrie, Cowie &Conran) and Stomoisia (Raf.) Kuntze from across each of their distributions. The phylogeny shows that Australiacontains species from the two major clades of section Oligocista, with each involving ancestors with yellow andpurple/mauve corolla colours. This study provides morphological and molecular evidence for recognition of anew species, Utricularia irwinica R.W.Jobson & Baleeiro, from Cape York Peninsula, Queensland. A lectotypeis designated for the name Utricularia cyanea var. alba Benth. We also recommend changes to the taxonomyof sections Enskide and Oligocista based on the phylogenetic results and morphology.

澳洲水蛭属(Utricularia section Oligocista)与纽约角特有种的分子系统发育研究

水藻科:(扁桃科)分布在新旧世界热带地区。我们使用核ITS和两个叶绿体标记的矩阵展示了分子系统发育，其中包括在每个物种范围内采样的37个已识别物种中的19个。系统发育研究还包括密切相关的Enskide部分的成员。P.Taylor(包括Minutae Lowrie, Cowie & Conran)和Stomoisia (Raf)。Kuntze从他们的每个分布中。系统发育表明，澳大利亚包含来自寡聚门的两个主要分支的物种，每个分支的祖先都有黄色和紫色/淡紫色的花冠颜色。本研究为识别新种乌tricularia irwinica R.W.Jobson &Baleeiro，来自昆士兰约克角半岛。一种卵泡类型被指定为蓝水藻变种白水藻。我们还根据系统发育结果和形态学建议修改Enskide和oligoista的分类。

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.
