Range DescriptionA. macrocarpa is native to the central Danube basin (Tutin et al. 1964). According to Euro+Med PlantBase (2006), it is native to Croatia, Former Czechoslovakia, Former Yugoslavia, Hungary, Romania, Serbia and Slovakia. It is a Pannonian endemic.
In Slovakia, this species is restricted to the Vchodoslovensk nina Lowland in the southeast of the country. The number of localities was recorded as c. 20 by Michalkov and Marhold (2002); however, only two localities are now known (Balla pers. comm. 2010).
In Hungary it occurs in the North Hungarian Mountains (Mtra margins), Great Hungarian Plain (Danube region, Danube-Tisza kze region and Tiszntl region) and South Transdanubia (Somogy and Szekszrd). It has a fragmented distribution, especially in northeastern parts of the country (So 1966, Simon 1992).
In Serbia it has a scattered distribution in Vojvodina and in the north of the country. It is extinct from a few localities in the surroundings of Belgrade (former Maki wetland) and Poarevac. In addition, the species has not been rediscovered since the second half of the last century in Fruka Gora and Deliblatska sands. Additional field investigations are needed as its distribution in Serbia is not well known.
In Romania it is only found at one locality in the southwest.
