1104. Dactylorhiza purpurella (T.Stephenson & T.A.Stephenson) Soó
Curtis's Botanical Magazine, Volume 41, Issue 2, Page 247-255, June 2024.Summary Dactylorhiza purpurella (northern marsh orchid) is illustrated here (t. 1104). It is a north‐western European allotetraploid species, and allotetraploidy and different treatments of the diploid progenitors of this and other allotetraploids in the genus have led to a complicated taxonomic history.

Chromosome Studies on Hydromystria laevigata (Hydrocharitaceae)
Annals of the Missouri Botanical Garden, 1985 Chromosomes of individuals from two Argentine populations of Hydromystria laevigata (Willd.) A. T. Hunz. were analyzed for numbers, meiotic behavior, and karyotype. It has n = 14 and 2n = 28. Both populations have regular meiosis and show no significant statistical differences between them. The karyotype is similar in both populations: asymmetrical and

Journal of Ecology, Volume 112, Issue 3, Page 446-460, March 2024.Our study highlights the relevance of evolution from common ancestors and shared history underpinning large seagrass phylogenetic structuring. Abstract Phylogenetic signal (PS) is the propensity of closely related species to resemble each other. PS has been tested across clades of terrestrial plants; however, insight for seagrasses is still lacking ...
