Introduction
A PhD candidate at the University of Queensland, I am dedicated to studying aquatic plants (genus Eriocaulon) from the Australasia, specially using this genus as model to explore genetic diversity and structure at the Great Artesian Basin. Utilizing the latest techniques in population genomics and phylogenomics, my work intends to shed light on the evolutionary history and genetic diversity of these fascinating species.

A new species of pipewort (Eriocaulon; Eriocaulaceae) from Cape York, Queensland was recently discovered. Eriocaulon insectum Baleeiro & R.W.Jobson is distinguished from all other species by its golden-brown inflorescence head, having female flowers with large, winged sepals with two black spots, four black, exerted stamens, with male sepals as a s...
The Utricularia lasiocaulis F.Muell. complex (subg. Polypompholyx; sect. Lasiocaules) is a morphologically and ecologically variable group of closely related taxa with a mostly tropical distribution across northern Australia. A recent molecular phylogenetic study placed the recognised species U. kamienskii F.Muell. sister to a clade of accessions r...
The genus Utricularia (Lentibulariaceae) is the most diverse and cosmopolitan among carnivorous plants. Utricularia sect. Foliosa sensu Taylor (1989) is composed of three South American species, U. amethystina, U. tricolor and U. tridentata, the first species being recognized as highly diverse. In his taxonomic revision of the genus Utricularia, Ta...
Ecotypes are distinct populations within a species that are adapted to specific environmental conditions. Understanding how these ecotypes become established, and how they interact when reunited, is fundamental to elucidating how ecological adaptations are maintained. This study focuses on Themeda triandra, a dominant grassland species across Asia,...
A new species of Utricularia (Lentibulariaceae) is recognised for north-eastern Western Australia. A description of Utricularia baliboongarnang Baleeiro & R.W.Jobson is provided along with a new circumscription for the Northern Territory species U. singeriana F.Muell. to which it was previously assigned. We also provide
comparison with U. hamiltoni...

As deforestation and fire move forward over pristine vegetation in the Amazon, many species remain undiscovered and may be threatened with extinction before being described. Here, we describe two new species of Utricularia (Lentibulariaceae) collected during recent fieldwork in an area of white-sand vegetation in the eastern Amazon Basin named Camp...
Across tropical northern Australia 14 Drosera species are recognised within the D. petiolaris complex. The complex is placed in section Lasiocephala; a group of perennial sundews mostly characterised by an indumentum of white hairs upon the petiole. Here we describe a new species for the complex, D. stipularis
The Utricularia dichotoma Labill. complex is a morphologically and ecologically variable group of closely
related taxa with a mostly temperate distribution across New Zealand, New Caledonia and Australia. Taxonomic
boundaries within the complex have been the subject of speculation, with several previously recognised species being
synonymised after...
Uncovering phylogenetic diversity is important, but not simple. A species complex is defined by different taxa with close evolutionary relationships harbouring limited morphological and/or genetic gaps. One such example exists within neotropical Utricularia sect. Foliosa, which is a taxonomically problematic assemblage composed of three currently r...
Utricularia biceps (Lentibulariaceae), a new species belonging to U. sect. Foliosa, is here described and illustrated. This new species is endemic to the campos rupestres of eastern Brazil, an extremely biodiverse and endangered vegetation. Notes on phenology, ecology, habitat, and conservation are provided, along with a discussion on the features...
Six new species of Utricularia (Lentibulariaceae) are recognised from northern Australia. Descriptions of the
new species Utricularia albertiana R.W.Jobson & Baleeiro, U. bidentata R.W.Jobson & Baleeiro, U. hamata
R.W.Jobson & M.D.Barrett, U. magna R.W.Jobson & M.D.Barrett, U. papilliscapa R.W.Jobson & M.D.Barrett,

Utricularia is a morphologically and ecologically diverse genus currently comprising more than 230 species divided into three subgenera-Polypompholyx, Utricularia, and Bivalvaria-and 35 sections. The genus is distributed worldwide except on the poles and most oceanic islands. The Neotropics has the highest species diversity, followed by Australia....
Phylogenetic relationships among all of the 47 recognised species and eight putative new taxa of Utricularia subgenus Polypompholyx, were assessed using maximum parsimony and Bayesian inference analyses of DNA sequences representing the plastid rps16 intron, trnL-F intron and spacer regions and the trnDT intron. We found strong jackknife and poster...
Resumo O presente estudo tem como objetivo contribuir para o conhecimento das espécies de Lentibulariaceae ocorrentes no estado do Rio de Janeiro. O trabalho tem por base a análise morfológica de materiais depositados em herbários e coletas de campo, além da compilação de dados de literatura. Foram registrados dois gêneros e 20 espécies. Chave para...
Lentibulariaceae is cosmopolitan, composed of three genera, Genlisea, Pinguicula, and Utricularia, containing ca. of 29, 100, and 220 species, respectively. The Itatiaia National Park is an elevated area with many rising rivers, lakes, wet places, and bromeliads. Therefore, it is promising to the occurrence of Lentibulariaceae species. However, stu...
Utricularia sect. Foliosa Kamiénski comprises three recognized species, U. amethystina Salzm. ex A.St.-Hil. & Girard, U. tricolor A.St.-Hil., and U. tridentata Sylvén, delimited based mainly on shape and structure of the corolla. In comparison with the two latter members of the section, U. amethystina forms a complex of morphological variants, refl...
Two new species of Utricularia (Lentibulariaceae) from the North West region of Western Australia. Utricularia byrneana R.W.Jobson & Baleeiro and U. wannanii R.W.Jobson & Baleeiro are described as new and are considered members of Utricularia subgen. Polypompholyx section Pleiochasia. The distribution and habitat preferences of these species are di...
Species from Utricularia sect. Foliosa and sect. Psyllosperma were studied based on seed characteristics. Our goals were to search for informative characters useful to species delimitations, especially for very polymorphic species such as U. amethystina, and also to provide an identification key and discussion about the delimitation of both section...
The Flora of Restinga de Jurubatiba National Park, Rio de Janeiro, Brazil: Lentibulariaceae - A taxonomic
study of Lentibulariaceae species found at the Restinga de Jurubatiba National Park, Rio de Janeiro, revealed that there is one genera and seven species: Utricularia erectiflora A. St.-Hil. & Girard; Utricularia foliosa L.; Utricularia gibba L....
A new species, , from the Brazilian savanna (Cerrado) is described and illustrated. This species was found growing at the Chapada dos Veadeiros National Park, and is distinguished from the other species in the genus by the presence of several rudimentary (or dormant) floral buds, sessile glands in the peduncle, and highly congested inflorescence. i...
Lentibulariaceae, carnivorous plant group, is characterized by modified leaves for aquatic and terrestrial microorganism capture. Composed of 325 species, with three genus of cosmopolitan distribution, Utricularia with 220 spp., Genlisea with 22 spp. and Pinguicula with 84 spp. and absent in Brazil. The study area is inserted in Cerrado domain, a c...

The Great Artesian Basin (GAB) is the largest groundwater reservoir in the world. It discharges across hundreds of spring vents, forming unique and complex wetland systems of various sizes from tropical Queensland to arid regions of South Australia and New South Wales. Ecological and phylogeographic studies, focused mainly on organisms from the Lake Eyre region of South Australia, indicate high spring endemicity due to isolation taxa over 1-4 MYA. The aquatic pipewort Eriocaulon carsonii occupies numerous springs of different sizes from Cape York to Lake Eyre. We aim to assess gene flow in E. carsonii and two microendemics across spring complexes, E. giganticum and E. aloefolium. SNP genotypes have been generated from ddRADSeq data from populations of E. carsonii, plus E. giganticum and E. aloefolium. In addition, 353 probe set has been adopted to reconstruct Eriocaulon species relationships and the origin and time of residency of Eriocaulon in the springs.
