Floral dynamics in the protandrous flowers of Bauhinia variegata (Fabaceae): phase-specific morphology, scent, and nectar production

Abstract Main conclusion Protandry in Bauhinia variegata is expressed through coordinated changes in floral morphology, scent composition, secretory activity, and nectar presentation, whereas petal reflectance remains stable; molecular docking further indicates that key phase-ass...

Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for i...

Flora of disjunct savanna formations in the Brazilian semiarid unveils biogeographical complexities in the Cerrado–Caatinga relationship

Abstract The semiarid landscapes of Northeastern Brazil host disjunct savanna formations, often broadly categorized under the term ‘northeastern cerrados’, whose biogeographical connections with the core Cerrado and Caatinga domains remain debated. While savanna formations on sed...

Humidity and temperature interact in breaking physical dormancy in Fabaceae seeds from the Brazilian semiarid region

Abstract Premise In semiarid ecosystems such as the Brazilian Caatinga, physical seed dormancy (PY) is critical for plant persistence when water is unpredictable, but how soil moisture and temperature regulate PY release and seed longevity in species of native Fabaceae that have...

How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

Societal Impact Statement It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still a...

Between Leaves, Prayers, and Healing Hands: A Cross-Regional Scoping Review of Ritual Healers and Plant-Based Community Knowledge

Plant-based healing practices integrate botanical resources, ritual speech, gesture, faith, spiritual mediation, protection, and social recognition within complex community systems of care. This cross-regional scoping review mapped the traceable literature on plant-based knowledg...
