Abstract: Seven morphological characteristics of 8 accessions of Alysicarpus vaginalis from south China were observed and measured,the correlations of morphological characteristics were analyzed and clustered . The results showed that: Abundant morphological variationexisted in accessions of Alysicarpus vaginalis; Morphological characteristics of had significant relationships. Based on seven morphologicalcharacteristics, accessions of Alysicarpus vaginalis from south China were clustered into three morphological types. The B, C populationmay be regarded as the excellent material used for the selecting and breeding of lawn grass.
