Természettudomány - László Papp–Miklós Dudás: Data on Botanical Values of Central and South Nyírség and their Vicinity

COMPOSITAE !! Aster linosyris Bernh. NY, Bátorliget (Nagylegelő), Rob. (originally Fest.-Q.) 50-60 specimens, drived out under the robinia trees, with other valuable species such as Iris aphylla ssp. hungarica, Pulsatilla grandis, Pulsatilla pratensis ssp. hungarica etc. On the basis of former data of literature (Soó, 1964-1980) its occurrence in NY was uncertain, but can appear on other places as well. ! Chrysanthemum serotinum L. NY, Bagamér-Álmosd (Daruláp), S.ci., S.p.-Bet. One by one, sometimes in smaller groups. ! Tussilago farfara L. NY, Nyírábrány (Nagyláprét), Scler-Trif. 20-30 specimens on the edge of tilling of the moorland and on the canal-bank. (!) Doronicum hungaricum Rchb. CR, Hencida (Csere Forest), (Máthé, 1939) A. tat.-Q., F.ps.-Q., Rob. This data is wellknown, but the considerable increase, especially in Rob. is not. There is area where the average number is over 8/m

2

! There is a trial to resettle it to the Sárándi Forest, (Soó, 1937) using seeds of this population. Probably the largest population of the country! (!) Ligularia sibirica Cass. NY, Bátorliget, (Soó, 1953) S. cin., S.p.-Bet. In 1986 as a result of artificial generative propagation made by L. Pólya 13 specimens were resettled replacing the extincted ones, mainly in the original associations. In 1987 7 of them started to grow well, but it would be useful to resettle further specimens, in order that individual number would exceed the minimal population size. ! Cirsium rivulare ALL. NY, Debrecen (Nagycsere: foot of Hármas Hill, Erőslyuk), Alop. pr.

, F.prat. Many specimens on some places, few on others. Nyírábrány (Nagyláprét and Kisláprét, Láperdő), Fii.-Ger., C.app., Mol.-c, F.prat., S.p.-Bet., S.cin., Thel.-A. Abundant, almost forms facies. Fülöp (around Tóthfalu), S, cin., F.prat., Fil.-Ger. Abundant. !!!(!) Hieracium aurantiacum L. NY! (Soó's data, marked by Tt, is wrong!) Álmosd (Daruláp). In May of last year looking for sensational find of P. Gergely (see Simon, 1977) it was stated that some hundred individuals occur on an area of about 50 m

2 with H. caespitosum, as well as cross-breeded with it! Endangered, because it is close to the cart-road and this part is used to approache inner roads. The association is probably transition of Ag.a. és F. prat, into marginal parts (Fil.-Ger.). Its protection, e.g. enclosure, is very urgent. ! Hieracium caespitosum Dum. NY, as the former one and in Nyírábrány (Láperdő) also some specimens. CARYOPHYLLACEAE (!) !!! Viscaria vulgaris Bernh. NY, Martinka (Vermes-side). Astr.-F., Arrh. 15
