| Abstract | ||||
| SEED and seedling morphology of 25 taxa from two sections and three subsections of the genus Medicago (Leguminosae-Papilionoideae) were studied using fresh materials. Seed, hypocotyl, paracotyledon, epicotyl and first leaf characters were used to construct an artificial key for identification purposes. Seed color and shape, radical length in relation to seed length, epicotyl color and hairiness, first foliage leaf shape and hairiness were all used as morphological descriptors for species identification. Cluster analysis was used to determine taxonomic interrelationships among the investigated taxa. The Spirocarpos and Medicago sections of Medicago L. were clearly distinguishable, whereas other sister taxa largely grouped together. | ||||
