population, Adonis volgensis, hybridization


In continuation of former cytological studies (1972) the paper presents phytochronological and phytocenological data regarding Adonis volgensis Stev. and A. hybrida Wolff from Romania, with special reference on an isolated point of the disjunct distribution of the species (Transylvania, Cluj, finatele Clujului, Fig. 1. D.III.22.; Fig. 2. D.III.22 12-13 and 22-23). At this point, on a restricted territory of about 1000 m2, a small population of A.volgensis can be found, which presents complex microevolutive phenomena as a result of introgresiv hybridization with a vastly out numbering population of A. vernalis L. The habitat of the species is steadily endangerd by herborizers and by rapid extansion of the city of Cluj. For the chorological representation of data the mapping system elaborated by A. Nyarady and E. C. Vicol (1973) have been applied, for the phytocenological processing the principles and symbolization of Central-European phytocenological school have been followed.
