Unique wetlands of the Pannonian Basin host an unexpected Batrachium diversity, including several morphologically cryptic cytotypes unknown elsewhere in central Europe. These lineages are closer to Mediterranean taxa than to their central European neighbours.

Why are allopolyploids common in Batrachium, but no diploid hybrids? This puzzle is now solved: a large-scale screening uncovered a natural hybrid between diploid species, providing new insight into the early stages of polyploid evolution.

Garden centres can host surprisingly diverse alien floras, including species not yet recorded in the country. A survey from Hungary shows they can also act as hubs of unintentional introductions and spread, including invasive species.

🌿 Coming soon: Preslia 98(2)! New insights into plant diversity, invasions and vegetation change:
🔹 Genome-size and ploidy data compiled for 1,103 Alpine plant species
🔹 Mediterranean Dittrichia graveolens continues its eastward spread along Slovak motorways
🔹 Even extreme rocky grasslands are changing, with rare xerophilous species in decline
Stay tuned for the full issue!

A new community resource for Alpine botany: flow-cytometric screening of ~45,000 silica-dried samples yielded genome-size and ploidy data for 1,103 plant species. Polyploids were found in 35%, with successful analyses for 97% of species screened.

🌿 Coming soon: Preslia 98(1)! New insights into central European flora:
🔹 87 taxa mapped reveal declines, extinctions, and newly recognised escaped diversity
🔹 Pannonian wetlands host unique Batrachium with Mediterranean links
Stay tuned!

New distribution maps for 87 vascular plant taxa reveal a flora under pressure: several species now survive at a single Czech site and four are nationally extinct. In contrast, taxonomic revision reveals 22 distinct escaped Cotoneaster species.

Even extreme dry grasslands on rocky outcrops are not stable. A 30-year resurvey in the Dyje/Thaya valley reveals declines of rare xerophilous species, spread of ruderal and nutrient-demanding plants, and strongest changes outside national parks.

Mediterranean Dittrichia graveolens is spreading along Slovak motorways, especially older sections. Its tolerance of mild frost and warmer summers, together with climate change, may support further eastward expansion through road corridors.
