Bluegrasses (Poa L.) of section Stenopoa is one of the most numerous, variable and intricate groups of grasses in temperate regions of Asia. The preliminary research of correlations and gepgraphical distribution of 5 main discriminators have been undertaken. It has revealed 54 combinations of characters states (among 96 possible), but only 22 of them could be attributed to identified species. Significant correlation was found between ligule length and surface of rachilla. The divergence in geographical distribution of ligule length (along longitude) and lemma callus (along latitude) has been revealed. It confirms the morphological and geographical divergence and has indicated the main trend. The most morphological diversity has been revealed in Chinese provinces Sichuan and Yunnan. https://www.biotech-asia.org/vol11_nospl_edn2/fitting-the-morphological-diversity-of-poa-sect-stenopoa-into-a-taxonomic-framework/ biodiversity; Poa L.; biogeography; Asia
