A new species of Utricularia (Lentibulariaceae) is recognised for the Northern Territory. A description of Utricularia gaagudju R.W.Jobson & Cherry is provided along with a new circumscription for the Western Australian species U. kimberleyensis to which it was previously assigned. Diagnostic features are illustrated, and distribution, habitat, and...

... Data used for the determination of stolon types and for the multivariate analysis of various biometric traits in subgenus Polypompholyx were gathered from morphological examinations using scanning electron microscopy on seven stoloniferous taxa, earlier works by Merl (1915) and Lloyd (1942), the monograph of genus Utricularia (Taylor, 1989), and subsequent species/section descriptions (Gassin, 1993;Lowrie, 1998Lowrie, , 2002Wakabayashi, 2010;Jobson, 2012Jobson, , 2013Jobson et al., 2017Jobson et al., , 2018aBaleeiro, 2015, 2020;Jobson & Cherry, 2020, Baleeiro & Jobson, 2022. Values of several traits were pre-evaluated Jobson et al., 2017) to the four sections of Polypompholyx as variable 'clade', and characters of trap wings to combinations with lateral appendages as variable 'trap type'. ...
... The morphological investigation on various stolons occurring in subgenus Polypompholyx revealed several branching patterns, which helped to interpret the stolon organization from more general notes on plant organs provided in the literature (mainly from taxonomic descriptions) across all currently known species of the subgenus. Since species descriptions may have been occasionally relied on sparse Jobson et al., 2017Jobson et al., , 2018aJobson & Baleeiro, 2020;Jobson & Cherry, 2020;Baleeiro & Jobson, 2022): sect.

To uncover the nature of various kinds of stolons of Utricularia subgenus Polypompholyx (Lentibulariaceae) we studied branching of stolons by scanning electron microscopy, statistically investigated correlations of stolon types and other traits across 56 species, and evaluated seedling development and process morphological aspects. Some results were compared to the sister genera Pinguicula and Genlisea . A key to nine stolon types in Polypompholyx is provided. Predominant stolon types were rhizoids, runner stolons with rhizoids on nodes, and runner stolons without rhizoids on nodes but with bladders on internodes. Stolon types were taxonomically relevant and correlated to the distribution/climate. They obviously diverged with speciation events in Australia. Examined seedlings of Genlisea and Polypompholyx showed similar developmental patterns. Stolons were homologous to traps and leaves. Selected subterranean organs contained specific but similar process combinations of roots, shoots and/or leaves. We assume the Genlisea - Utricularia ancestor trap included processes of a Pinguicula root and leaf.
