How does a plant species swarm maintain coexistence on an isolated mountain in northern Madagascar?
Background and aims – Madagascar’s rich flora originated mostly from in situ diversification, and the large-scale plant species richness pattern is mainly explained by spatial heterogeneity. However, mechanisms underlying plant community assembly remain largely unexplored. We aimed to understand…

Understanding vegetative and reproductive phenology in a cycad species with a wide distribution pattern: responses to the local environment
Background and aims – The timing of seasonal life cycle events is important for developing assessments of the extinction risk status, understanding the responses to climate change, and even evolutionary strategies. Many studies on phenology have been published about the impact of climate change…

Does size matter? Pollination biology of Aristolochia sessilifolia (Aristolochiaceae)
Background and aims – The morphology of flowers with specialized pollination acts as a pollinator filter, resulting in compatibility between the flower and its visitors. These characteristics can influence plant diversity, and studying these interactions provides important models for understanding…

Morphological redescription and ecological niche modelling of Gustavia santanderiensis (Lecythidaceae), with a key for the genus in the Magdalena Valley, Colombia
Background and aims – Gustavia santanderiensis is a tree species from the Magdalena Valley described around a century ago. Despite the species’ morphological plasticity, restricted range, and ecology, the species has been greatly understudied. This study aims to establish a clear taxonomic…

An infrageneric classification of the genus Lejeunea (Marchantiophyta: Lejeuneaceae) using molecular phylogeny and morphology
Background and aims – The genus Lejeunea, with about 375 accepted species, is one of the most species-rich and intricate genera of liverworts. Here, we present the first integrative, worldwide infrageneric classification of Lejeunea based on morphology and molecular-phylogenetic analyses. Material…

Geographic variation in compensation to damage in common milkweed (Asclepias syriaca)
Background and aims – Plants display a variety of resistance and tolerance responses to herbivory. Compensation, or changes in growth, allocation, and/or physiology, after damage is one way that plants tolerate herbivory, but geographic patterns in intraspecific plant compensatory responses are…

Pollen grain evolution in Zornia evidences the homoplastic nature of a stenopalynous genus of Leguminosae
Background and aims – Zornia is the only pantropical genus in the Adesmia clade (Dalbergieae), subdivided into two clades by previous phylogenetic studies. Zornia remains the only genus of the Adesmia clade to be palynologically understudied. We present a comprehensive palynological study for this…

Discovered far from home: a new Medicago species (Fabaceae) of unknown origin, associated with historical wool imports in Belgium
Background and aims – A previously undescribed species of Medicago was discovered in Belgium. Its identification and characterization are important for understanding non-native plant introductions linked to historical human activities. Material and methods – Morphological traits of the single…

Climatic niche conservatism and Pleistocene range dynamics in two Mediterranean Cistus species
Background and aims – Understanding how closely related species diverge is a fundamental issue in evolutionary biogeography, particularly in regions formed by repeated climatic oscillations. We examined the drivers of geographic separation between Cistus albidus and Cistus creticus across the…

Germination ecology of the critically endangered sainfoin Onobrychis conferta subsp. conferta and the rare O. caput-galli (Fabaceae)
Background and aims – Understanding germination and seedling emergence responses of pastoral legumes is essential for improving conservation and restoration efforts, particularly in arid and semi-arid ecosystems. This study aimed to characterize the germination ecology of two threatened taxa…

Untangling the Nautilocalyx pallidus complex (Gesneriaceae) with description of a new species and a new combination
Background and aims – Nautilocalyx pallidus is a broadly circumscribed species originally described from Peru under which several morphologically distinct taxa have historically been misidentified. As part of an ongoing taxonomic revision of Nautilocalyx, this study aims to re-evaluate the…

Resolving the Magnolia pacifica complex (Magnoliaceae): a coalescent-based approach reveals five distinct evolutionary lineages
Background and aims – Species delimitation using multilocus coalescent-based methods has provided new insights into evolutionary processes and species boundaries. In this study, we applied a multilocus, multispecies coalescent framework to investigate species limits and estimate divergence times…

A new dwarf palm from the campo rupestre: another piece of the Syagrus evansiana complex (Arecaceae)
Background and aims – In the Espinhaço Range, the campos rupestres harbour many endemic acaulescent Syagrus. Populations assigned to Syagrus evansiana include geographically and ecologically distinct populations. We reassessed the two populations used in the original circumscription of S. evansiana…

Novelties in Psittacanthus (Loranthaceae) from Colombia: a new species and four new records for the Andean and Amazon Regions
Background and aims – Psittacanthus is the largest genus of neotropical mistletoes within Loranthaceae, comprising approximately 110 species. With 37 species recorded to date, Colombia stands as the most diverse country for this group of aerial hemiparasites. Despite this richness, a comprehensive…

Rediscovery of Lysimachia peduncularis in China: amended description, complete plastid genome, and phylogenomic placement in subgenus Idiophyton (Primulaceae)
Background and aims – Lysimachia peduncularis has not been recorded in China for nearly half a century. Its recent rediscovery in southern Yunnan provides a critical opportunity to update its taxonomic description, clarify its nomenclatural history, and re-evaluate its systematic placement using…

Three new cryptic species of Begonia section Baryandra (Begoniaceae) from the Philippine archipelago supported by morphological and molecular evidence
Background and aims – The Philippine archipelago harbours the world’s greatest diversity of flowering plants, yet it is identified as a global plant diversity darkspot where much of this diversity remains poorly documented and inadequately sampled. To address this knowledge gap, extensive botanical…
