Pollen Morphological Peculiarities of Selected Mimosoideae Taxa of Hainan Island and Their Taxonomic Relevance

Mimosoideae is one of the taxonomically complex subfamilies Fabaceae. Several studies have reported pollen morphology taxa and their taxonomic relevance, but no such study was found specifically for Hainan Island in southern China. Therefore, present designed to investigate selected explore new palynological traits support strengthen systematics using multiple microscopic techniques. The polar axis, equatorial diameter grains, colpus length width were measured. smallest grain size Mimosa pudica (7.8 × 7.75 µm), while largest Albizia lebback (87.54 77.97 µm). Similarly, significant variation exine surface patterns. subfamily considered eurypalynous because traits. In addition, also quantitative Comparatively, features be helpful at genus species levels, as well correct identification discrimination taxa. Hence, this gives a detailed account morphologies certain collected from different geographical regions on Island. morphological proven potential can used additional tools These results will provide basis further systematic studies.
