Ajuga reptans L. - Occurs in hornbeam-oak woods on the northern slope of Tábla-hegy; rare. (BAUER 1996). Alcea biennis Winterl (Syn.: Althaea pallida W. et K.) - Occurs north of Strázsa-hegy in a degraded "loess grass". (KUN and SEREGÉLYES 1995, BAUER 1996). Alisma plantago-aquatica L. - Occurs in the environs of ponds established south of Strázsa-hegy and in hygrophilous plant communities near Szentléleki-patak. (KUN and SEREGÉLYES 1995) . Alkanna tinctoria (L.) Tausch - (FEICHTINGER 1899). Alliaria petiolata (M. B.) Cavara et Grande - In forests and various weed associations of the area; it reaches very high cover (80%) in the placor region of Tábla-hegy in a pubescent oak wood.

Schmidt) Janch. - Occurs in large numbers near the top of Strázsa-hegy in the grass community dominated by Bromus erectus, on the northern slope (FEICHTINGER'S (1899) data of Allium acungulum might refer to this species). (KUN and SEREGÉLYES 1995). Allium sphaerocephalon L. - Appears in large numbers in spots in the steppe grass slope meadows and in the "steppe grasses" on the eastern foot of Tábla-hegy. Sporadic in dry steppe meadows around the hills. (BOROS 1919, KUN and SEREGÉLYES 1995, BAUER and BARNA 1999). Allium vineale L. - Appears in disturbed steppe meadows southeast of Tábla-hegy. (BAUER 1996) . Alyssum alyssoides (L.) Nath. - Frequent in dry grassy areas of the area. (BOROS 1920, KUN and SEREGÉLYES 1995, BAUER 1996). Alyssum montanum L. - (FEICHTINGER 1899).

Amaranthus retroflexus L. - Occurs in masses on the burrow at Sátorkőpuszta, frequent in weed communities. Ambrosia artemisiifolia L. - Frequent in weed communities, but also appears in open "sand grasses". It has not been observed in big masses. (KUN and SEREGÉLYES 1995, BAUER 1996). Anacamptis pyramidalis (L.) Rich. - On the northeastern chine of Strázsa-hegy at 270 m elevation above sea level there is a population with a small number of individuals in a "steppe grass" slope meadow developed partly after clearing. (BAUER 1996). Anagallis arvensis L. - Appears in weed communities on disturbed surfaces. (BAUER 1996). Anchusa officinalis L. - Sporadic in weed communities and in degraded "sand grasses". (BOROS 1919, KUN and SEREGÉLYES 1995, BAUER 1996). Anemone ranunculoides L. - Frequent on the northern slope of Strázsa-hegy, especially in the ravine forest; rare in other places. Anemone sylvestris L. - Occurs in limestone preferring oak woods, shrub forests and in their clearings and in different types of steppe meadows. Seen also in massive paches on the southern slope of Tábla-hegy and on the northern slope of the largest sandhill lying south of Strázsa-hegy. (KUN and SEREGÉLYES 1995, BAUER 1996, BAUER and BARNA 1999).
