Penksza, Károly: Flora of the Őr-hegy (Gerecse Mts, Hungary)

40 PENKSZA, K. RESULTS AND DISCUSSION Altogether 459 vascular plant species were found in the investigated area. Among mosses 13 species were identified. FEICHTINGER (1865, 1899) reports on several species, which I have not found yet, they can be considered extinct from the area, but can be found in the collection of the Botanical Section. These are: Trigonella monspeliaca L., Malcolmia africana (L.) R. Br., Teucrium botrys L., Cerastium brachypetalum Desp. and Valerianella carinata Lois. However, FEICHTINGER mentioned some species that I could find neither in the area, nor in the herbarium of the Botanical Department: Carex supina Wahlbg., Festuca drymeia M. et K., Ornithogalum refractum Kit. ex Willd., Myosotis sylvatica Hoffm., Peucedanum arenarium W. et K. and Thesium bavarum Schrank. It is most probable that these species have become extinct. Three of the species mentioned by BOROS (Verbascum speciosum Schrad., Geranium rotundifolium L. and Hieracium pallidum Biv.) were not found later. BOROS (1938) reported Cotoneaster tomentosus (Ait.) Lindley occurring on the Őr-hegy. Later in his phytogeographical work he pointed out that the area of this species coming from the direction of the Vértes Mts to stops at Kakukk-hegy near Szomor (BOROS 1953). However, a large population of Cotoneaster tomentosus (Ait.) Lindley can be found now on the Őr-hegy. Cotoneaster niger Fig. 3. The evaluation of nature conservation ranks (SIMON 1992) of the species occurred on the Őr-hegy
