RESULTS AND DISCUSSION Distribution of culms according to internode numbers The author made a comparision of the internode numbers of culms bearing panicles on 320 specimens from 13 populations. The comparision between the two Sesleria taxa was made with experimental probability (frequency), and the differences between the specimens collected from the original habitats (220 specimens from 9 populations) and those grown in the experimental garden (100 specimens from 4 populations), (Fig. 1, Tables 1-2). As regards the specimens grown in the original habitats the double internoded culms (culms with 2 internodes) are the most frequent and, in an interesting way, of the same rate, 64% in both Sesleria taxa. After that follow the culms with 3 internodes, also of the same percentrage in both Sesleria taxa: 27% level. Difference beetween the two closely related taxa is found at 9-9%. That means culms without node - culms with 1 internode - at Sesleria heufleriana (9%) and culms with 4 internodes at Sesleria hungarica (9%).
