Stomatal evolution and plant adaptation to future climate.
Global climate change is affecting plant photosynthesis and transpiration processes, as well as increasing weather extremes impacting socio‐political and environmental events and decisions for decades to come. One major research challenge in plant biology and ecology is the interaction of photosynthesis with the environment. Stomata control plant gas exchange and... -

Marsh-orchids of Canada: long-standing mysteries partially solved.
Between 1959 and 1988, three populations of purple-flowered terrestrial orchids attributable to subgenus were discovered in Canada. The populations at Timmins, Ontario, and St John's, Newfoundland were strongly marked on both flowers and leaves, in contrast with the anthocyanin-deficient population at Tilt Cove, Newfoundland. All three populations have since experienced... -

Molecular phylogenetics of Distephanus supports the recognition of a new tribe, Distephaneae (Asteraceae).
Distephanus Cass. comprises 43 distinctive species of shrubs and small trees that have been placed historically within the ironweed tribe, Vernonieae (Asteraceae). Using the most expansive sampling of Distephanus to date, this study aims to test the monophyly of this genus and facilitate its classification. Molecular phylogenetic analyses were conducted...Gostel, M. R. ; Loeuille, Benoit ; Santana, Mariana Henriques ; Kelloff, Carol L ; Chan, Raymund …

Phylogenomics and the rise of the angiosperms
Angiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods1,2. A robust understanding of angiosperm evolution is required to explain their rise to ecological dominance. So far, the angiosperm tree of life has been determined primarily by means of analyses of the plastid genome3,4. Many studies have drawn on...Zuntini, Alexandre R. ; Carruthers, Tom ; Maurin, Olivier ; Bailey, Paul C. ; Leempoel, Kevin …

Estimation of contemporary effective population size in plant populations: Limitations of genomic datasets.
Effective population size ( ) is a pivotal evolutionary parameter with crucial implications in conservation practice and policy. Genetic methods to estimate have been preferred over demographic methods because they rely on genetic data rather than time‐consuming ecological monitoring. Methods based on linkage disequilibrium (LD), in particular, have become popular... -

A glimpse into the diversity of Colombian Acanthaceae.
A short visit to four Colombian herbaria in 2022 is highlighted as an example of modern-day herbarium plant hunting which resulted in the discovery of 14 new species: J.R.I.Wood, J.R.I.Wood & Hoyos-Gómez, J.R.I.Wood, J.R.I.Wood, J.R.I.Wood & Hoyos-Gómez, J.R.I.Wood & Hoyos-Gómez, J.R.I.Wood, J.R.I.Wood & Hoyos-Gómez, J.R.I.Wood, J.R.I.Wood, J.R.I.Wood, J.R.I.Wood & Hoyos-Gómez...Wood, John R.

Tarenna thorelii (Rubiaceae), a new record for Thailand.
Tarenna thorelii is reported as a new record for Thailand based on collections from Khon Kaen and Roi Et Provinces. A morphological description based on Thai specimens, distribution, ecological information, conservation status, and short notes on the species as well as an illustration are provided. In addition, a lectotype for...Wirot, Wirot ; Chantaranothai, Pranom

Clusia salicifolia (Clusiaceae), a new hemiepiphyte species from Costa Rica and Panama.
We describe and illustrate (Clusiaceae) a new species from Central America. This new species is different to all related species for its hemiepiphytic habit, narrow leaves with acute to acuminate apex, reticulate resin canals, staminate flowers with quadrangular androecium with 30 – 47 free stamens, and pistillate flowers with 4...Wodcke, Emma A. ; Luján, Manuel ; Hammel, Barry

Phylogenetic trends in TZ staining analysis of six deep dormancy seeds.
The assessment of seed quality and physiological potential is essential in seed production and crop breeding. In the process of rapid detection of seed viability using tetrazolium (TZ) staining, it is necessary to spend a lot of labour and material resources to explore the pretreatment and staining methods of hard...Peng, Chen Yin ; Wu, Yu ; Huang, Wen Hui ; Deng, Zhi Yun ; Sun, Xiao Rui …

Pollen morphology of the Sapotaceae from Thailand and its taxonomic implications.
The external pollen morphology of the family Sapotaceae in Thailand was examined using the acetolysis method to determine its taxonomic significance. Pollen of 39 specimens belonging to 32 species was investigated by means of light and scanning electron microscopy. Pollen grains are found to be monads, isopolar, colporate, lalongate, and...Kunasit, Pongsakorn ; Chantaranothai, Pranom
