of the sepal; 11. the length of the capsule per that of the petal; 12. the total length of the lateral branches per the length of the whole stem; 13. the arithmethic mean of the length of internodes; 14. the arithmethic mean of the length of leaves. Character 1 is multiplied by 10; characters 2, 3, 10-12 are given in percentage; characters 3, 13, 14 are given in mm; characters 5-8 are given in mm/10. The arithmetical means with the P = 95% confidence intervals of data (characters 1, 4, 8, 13, 14) are given in Table 4. Regression analysis was carried out on the following data: the length of sepals against that of petals; the length of sepals against that of the capsules; the length of petals against that of capsules; the number of internodes with lateral branches against the number of internodes; the avarage length of internodes against that of the leaves. The regression coefficients and the BRAVAIS correlation coefficients are given in Table 5. Some relations are plotted in Figs. 1-4. Cluster analysis was carried out first with the 14 characters, and second with the characters 1-3, 5-9 and 14, on the 45 specimens Characters 4,12 and 13 were neglected because of their irrelevance (compare with Table 4). The characters 10 and 11 were omitted in order to reduce the proportion of generic characters. We used the similarity coefficients of CZEKANOWSKI (1909), HORN ( 1966), HUMMON (1974) and the chord-distance of ORLÓCI (1978). The UPGMA fusion technique was used for the similarity coefficients (SOKAL & SNEATH 1963) and the sum of squares method for the chord-distances (ORLÓCI 1978). Dendrograms were more or less similar to each other; here we present two of these (Figs. 17, 18) calculated by the CZEKANOWSKI coefficient and UPGMA, since they gave the clearest results. CAMPBELL (1978) in his investigations found the CZEKANOWSKI coefficient the most proper. D

The numerous synonyms of the genera show what different names were given by various authors. Before and after LINNÉ (1753, 1762) many authors tried to find an expressive name for this genus. LINNÉ (I.e.) also changed the oldest name Alsine (BAUHINI 1623, MORISON I.e.) for Arenaria, but in descriptions he reverted to the oldest literature. The Tissa and Buda described by ADANS (I.e.) were only two generic names. ADANS, Fam. pi. 2: 507 Tissa Feuilt Flows Calice Corolle EtamiPistil Fruit Graines les Solit. 5 5 nes 3 stil.

According to LEBEL (I.e.) these two name are invalid, since ADANS did not differentiate Spergula from Spergularia.
