Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal Optimisation

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Many leaf gas exchange models predict that photosynthesis and stomatal conductance are tightly coupled and respond in parallel to changing environmental conditions. However, experiments show that when temperatures increase beyond the thermal optimum of photosynthesis, stomatal conductance may continue to rise while photosynthesis declines, facilitating

Forest Herb‐Layer Species Richness in the Western Balkan Diversity Hotspot

open access: yesJournal of Vegetation Science, Volume 37, Issue 4, July/August 2026.
Forest herb‐layer richness in Montenegro ranges from 7 to 149 species per 100 m2. Thermophilous oak forests on base‐rich soil often harbour more than 90 vascular plant species per 100 m2. Mean annual temperature, summer precipitation, terrain ruggedness, soil pH and tree‐layer cover are the main factors shaping herb‐layer species richness patterns ...

Henry Trimen: Under‐appreciated pioneer in the typification of Linnaean plant names?

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract In 1887, Henry Trimen published a paper summarising the contents of the Hermann Herbarium, in what is now the Natural History Museum, London (BM), in terms of the plant names published by Linnaeus. Trimen referred to the Hermann specimens as types of Linnaeus's names.
