Sažetak
The work outlines the earlier published literature data on the localities of Hippophaë rhamnoides L. in Croatia (Schlosser & Vukotinović 1869, Pichler 1891, Hirc 1906, Trinajstić 1984, Z. Pavletić 2005). H. rhamnoides is a relict glacial species whose few localities in the Drava River riparian zone in a wider area around Varaždin have been destroyed during the hydrotechnical works in the construction of the storage lake for the Hydro-Electric Power Plant “Varaždin”, and which, therefore, according to Nikolić & Topić (2005a) belongs to the category of “regionally extinct taxa”.
In the Drava River riparian zone near Križovljan-grad, in the spring of 1996, the small stands were discovered where H. rhamnoides was present. There, this species builds a separate underbrush community – the ass. Hyppophao-Berberidetum Moor 1958, and so far it is the first and only locality of the said community in Croatia.
In the analyzed phytocenological relevé, 15 species have been registered out of which 10 species are characteristic for particular syntaxa, while 5 species belong to the companion species, as can be seen in the attached relevé.
Particularly interesting is that in the floristic composition prominent among other bushy species is a special ecotype of the Scotch pine – Pinus sylvestris, a low tree having the characteristic, twisted trunk as the pioneer species in overgrowing the gravel riverbanks.
