!, !!! Gentiana pneumonanthe L. NY, Nyírábrány (Nagyláprét), Mol.c, S.cin., S.p.-Bet. Quite abundant, in 1986 more than 180 specimens. Mowed in 1987, only some flowering specimens that year. In 1988 over 160 flowering and 30-50 non-flowering specimens! The last significant population of NY, since that of Haláp (Soó, 1932) seems to be extinct on the basis of our investigation and no new information is known on population of Nyírbéltelek. (We deal with artificial propagation, see further publication) (See paralel publication of J. Sípos (1989) !, !!! Menyanthes trifoliata L. NY, Nyírábrány (Nagyláprét), C.-Men. S.p.-Bet. Two subpopulations. About 100 specimens in the bigger one (in the first association), though part of it is probably spontaneous vegetative increase. Altogether 10-15 specimens in the other subpopulation, in filled parts. (!),!!! (Conservation of the area protected by the county in Hajdúsámson (Siroki, 1952, 1958) is not resolved yet. Salix cinerea should be drived back time by time, etc. Probably B. Tikos (1928) describes the same ares in "Formation of recent forests of Debrecen" and Z. Siroki's paper does not include it by mistake.) BORAGINACEAE (!) Cynoglossum hungaricum Simk NY, Martinka (Vermes-side), Bagamér (Daru Hill) (Soó, 1934) Brom, t., F.-Cor., PotF.ps. Sporadically. ! Ujléta (around Csohos tó), Brom.t., F.-Cor. 10-12 specimens. ! Terem (Teremi Forest: Vargatag), Pot.-F.ps. Some specimens. ! Nyírábrány (Pasture, Keszlertag), Pot.-F.ps. Some specimens. !, !!! Lithospermium purpureo-coeruleum L. NY, Bánk (Bánki Forest: behind the Ludas Inn), Conv.-Q. Some specimens. Debrecen (Nagycsere: Csere Forest, „botanical garden"), Conv.-Q., Fest.-Q. Sporadically. (On the latter habitat it was found by L. Juhász and L. Tóth as well.) !, !!! Onosma arenaria (pseudoarenaria) ssp. tuberculata Jáv. NY, Bagamér (Daru Hill), Pot.-F.ps. In 1988 only 3 specimens, as a result of pasturing (mainly geese). (!) Hajdúbagos (sand-hills of Nagy-nyomás), (Soó, 1934) Pot.-F.ps. In considerably higher number! (See publications of J. Sípos 1988.) !, !!! Újléta (Csohos Lake), F. vag. 10-12 specimens. This species, however resistant it is, has been extincted from numerous habitats of NY, as a result of intense and not appropriate pasturing. !, !!! Echium russicum J. F. Gmel. Border of CR and NY, loess snapping off between Létavértes and Pocsaj. Salv.-F. It was found in 1987, there were only some specimens. In 1988 the same number was estimated, with G. Kovács and A. Molnár! (!) !!! Bátorüget (Nagylegelő), Pot.-F.ps. Seems to be extinc! LABIATAE ! Leonurus marrubiastrum L. NY, Debrecen, (Nagyerdő), Fr.p.-U. Some specimens. 13
