SEM Pollen Morphology of Columnar Cacti Polaskia from Tehuacán-Cuicatlán Valley, Mexico

Scanning Electron Microscopy (SEM) analysis of Polaskia columnar cacti from the Tehuacán-Cuicatlán Valley reveals distinct pollen morphological traits that contribute to understanding the species' reproductive biology and taxonomic relationships. The study identified key features such as pollen grain size, exine structure, and surface ornamentation, which vary among Polaskia taxa. These findings provide insights into the evolutionary adaptations of columnar cacti in this region, known for its high biodiversity and cultural significance. The research employed SEM to examine pollen samples, offering a detailed characterization that enhances our knowledge of Mesoamerica's native flora.
