Újléta (Csohos Lake) Conv.-Q. tib. Fr. p. - U. 8-10 specimens. (In the latter association with other important species!) !, !!! Adorns vernalis L. NY, Bagaméri Forest (around Vámospércs). Fest.-Q. Only one, probably the last specimen. Bánk (Bánk-Monostorpályi Forest: Around the Csík dam). 6 specimen in Fest.-Q. and hibrid poplar consociation. (We found it on the basis of Tamás Barna's verbal publication.) (!) !!! [CR., loess snapping off between Létavértes and Pocsaj (at the border of CR and Ny!) Endes (1988) publishes since its survival is a miracle, but this habitat has been known (Soó, 1964-1980; 1973). By our investigation of 1987-88 there are over 400 specimens, mainly in the erosion valleys, in some places in Rob. (probably after Ac. t. - Q. and Salv.-F.)]. (!)!!! NY, Bátorliget (Nagylegelő). (Boros, 1924 Soó, 1935,1939) Astr.-F., Pot.-F. ps. and in other local nitrophilous ruderal grass. Today the old marvellous population (several thousands of individuals) consists of altogether 26 specimens (20 in original associations, 6 further, in ruderal association.) Probably the oldest specimen of NY is found here. It can be as old as several hundred years, sometimes has 60-80 blossoms! Artifical propagation and resettling are very urgent! Adonis eastivalis L. NY, Hajdúbagos (Nagynyomás, edge of Ördögárok). Young Alnus glutinosa planting (originally Fr. p. - U.). Diminished in original associations. ROSACEAE (!)PotentillaalbaL.

Astr.-F., Pot.-F. ps. in smaller groups (with 5-10 specimens), sporadically on large area. Heavily diminished in NY. 10
