Rhododendron diversity patterns provide new insights for conserving China's montane flora

Journal of Integrative Plant Biology, EarlyView.
Integrating distribution, phylogenetic, and functional trait data for 603 Rhododendron species in China identified significant conservation hotspots of multidimensional diversity, particularly in the Hengduan Mountains. Climate seasonality and topographic heterogeneity jointly influenced these patterns; however, notable conservation gaps remained ...

Organelle genome evolution in the early‐diverging brown algal lineage, Ishigeales

Journal of Phycology, EarlyView.
Abstract The order Ishigeales is an early‐diverging lineage of brown algae that exhibits remarkable morphological diversity ranging from simple filamentous forms to robust terete and foliose thalli, which may reflect complex evolutionary histories in their organelle genomes.

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

Journal of Phycology, EarlyView.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

Journal of Systematics and Evolution, EarlyView.
Using Angiosperms353 and plastid genome skimming approaches, the generic limits of Hyacinthinae were explored using DNA sequences to better understand their evolution. Floral morphology, a traditional generic delimiter, conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define similar groups to DNA.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Map of sampling for each species, chloroplast and mitochondrial genome phylogeny. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of one species become fixed in another following hybridization and backcrossing, a phenomenon known as organelle capture.

Oxytropis ikhbogdicus (Section Mesogaea, Fabaceae), A New Species From Mongolia Based on Morphological and Molecular Analyses

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Oxytropis ikhbogdicus, a new species endemic to Mongolia, is described and illustrated. The new species was confirmed by phylogenetic analysis based on the complete plastome genome and combined nuclear ribosome internal transcribed spacer (ITS), psbA‐trnH, and trnF‐L sequence data as well as morphological characteristics. ABSTRACT Oxytropis ikhbogdicus,

Elsholtzia yajiangensis (Lamiaceae), a New Species From Sichuan, China

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Adds to the understanding of species diversity in the taxonomically challenging genus Elsholtzia, particularly in the biodiversity hotspot of the Hengduan Mountains. Demonstrates the utility of combining shallow whole‐genome sequencing and morphometrics in resolving species boundaries in closely related shrubby taxa.

A New Species of Arthropteris From Samoa

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly < 3 cm wide vs.
