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.
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.
