Redefining taxonomic boundaries of the genus Galtonia (Hyacinthaceae) and a new genus, Stellifloris, described

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Genera form the basis for higher taxonomic classification and should be easily recognizable, predictive, and stable, and should reflect the evolutionary history of their constituents, with monophyly as a key principle of modern classification.

Reconciling morphological and molecular approaches: The integrative taxonomy of Leucobryum (Leucobryaceae) in the Malagasy region

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Leucobryum (Leucobryaceae) is a genus of moss (Bryophyta) that has been poorly investigated in Africa, particularly in the western Indian Ocean region. This study integrates morphological and molecular data to revise the taxonomy of the genus in this area.

Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

Where Lineages Persist: Phylogenetic Patterns and Evolutionary Vulnerability in South Africa's Herpetofauna

open access: yesDiversity and Distributions, Volume 32, Issue 8, August 2026.
ABSTRACT Aim Conservation under the current global biodiversity crisis demands strategic prioritisation to maximise the impact of limited resources. This study aims to integrate evolutionary history, an often‐overlooked component of biodiversity, alongside extinction risk to identify priority species and regions, assessing both the feasibility and ...

Ibero‐Balearic plant disjunctions: genomic support for rapid and recurrent long‐distance colonizations of the endangered Diplotaxis ibicensis (Brassicaceae) despite no dispersal syndromes

open access: yesPlant Biology, Volume 28, Issue 5, Page 1560-1572, August 2026.
Genotyping‐by‐sequencing data reveal six well‐defined clades in the endangered Diplotaxis ibicensis, endemic to the western Mediterranean Basin and indicate rapid and recurrent long‐distance colonisations across the Balearic Islands and the eastern Iberian coast despite the absence of dispersal syndromes.

Extroparvum occidentale gen. et sp. nov. and the Cretaceous diversification of Lauraceae

open access: yesAmerican Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise The fossil record of Lauraceae extends back to the Early Cretaceous and comprises numerous flowers. However, phylogenetic relationships of many of these fossil flowers remain unresolved. To better understand the early evolutionary history of Lauraceae, we conducted phylogenetic analyses of living and extinct members of the family and ...

Symbiotic Versatility in Action: Trebouxia Diversity Expands the Niche of the Lichen Xanthoria parietina

open access: yesEnvironmental Microbiology, Volume 28, Issue 7, July 2026.
Xanthoria parietina associates with an unexpectedly high diversity of Trebouxia phycobionts within clade A across the Mediterranean Basin. Climatic niche modelling reveals that differences in photobiont climatic preferences contribute to symbiont switching and help explain the broad ecological amplitude and geographic success of this widespread lichen.
