Micromorphological visualization of plant surface peculiarities provides valuable characters for the precise identification of plant species. Invasive alien species, introduced outside their native range, pose significant ecological, and health challenges. This study focuses on micromorphological investigations of selected invasive plant species belonging to the families Amaranthaceae, Asteraceae, Moraceae, Crassulaceae, Cannabaceae, Fabaceae, Commelinaceae, and Oxalidaceae. The study employs scanning electron microscopy (SEM) to analyze the species micromorphology of pollen structure in depth to characterize the sculpturing patterns. Additionally, the study examines the pollen characteristics of these invasive plants, including shape, size, and fertility, along with exine sculpturing. The maximum polar diameter was observed for Senna tora (41.2 μm). The spines in Achillea fragrantissima were measured to have dimensions of approximately 1.91 μm in length and 2.11 μm in width. The findings shed light on the allergy‐causing potential of these invasive species, providing crucial information for accurate identification and effective management strategies to safeguard the indigenous flora of the region. The study contributes to the knowledge base for botanists, taxonomists, policy makers, climate experts, and biodiversity specialists.Research Highlights Integrating SEM to analyze the pollen of invasive species. Unveiling pollen micromorphology of invasive species. Exploring the microscopic realm of invasive pollen to accurately identify the species.

“…In Egypt, this genus is represented by four species and two varieties belonging to three sections in the subgenus Oxalis (Draz et al, 2021;Shamso et al, 2021). The current study presents a description of the macro-and micromorphology of pollen grains and foliar epidermal cells using both LM and SEM for the evaluation of their taxonomic significance and uses numerical taxonomy to better understand the phenetic relationships among the studied taxa within the genus.…”

By using light microscopy (LM) and scanning electron microscopy (SEM), the pollen grains and foliar epidermal morphology of four species and two varieties of Egyptian Oxalis Linnaeus, 1753 belonging to three sections of the subgenus Oxalis Linnaeus, 1753 were studied. The objective was to determine the importance of pollen and foliar epidermal characters as taxonomic evidence. The current study revealed that the pollen grains of all taxa examined are monads, radially symmetric, isopolar, and of medium size; the shape varied from sub-spheroidal to subprolate. The pollen apertures were tricolpate with ornamented colpal membranes (rugulate, warty, congregated granules). Exine is semi-tectate, with micro-reticulate to reticulate ornamentation, perforate in O. debilis Kunth, 1822. The study also revealed the presence of four types of stomata: actinocytic, anisocytic, anomocytic, and an unusual 4-celled anisocytic. Both abaxial and adaxial epidermal cells were irregular or polygonal in shape, with undulate or straight anticlinal walls and semi-swollen to swollen periclinal walls with dispersed epicuticular wax. Two forms of non-glandular, unicellular trichomes were observed: short clavate and long with a tapering apex and papillate surface. The study further discussed numerical results based on combined morphological, palynological, and foliar epidermal characters. This study is the first report dealing with anatomical and palynological features of the genus Oxalis in Egypt.
