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 Východoslovenská nížina Lowland in the southeast of the country. The number of localities was recorded as c. 20 by Michalková and Marhold (2002); however, only two localities are now known (Balla pers. comm. 2010).
In Hungary it occurs in the North Hungarian Mountains (Mátra margins), Great Hungarian Plain (Danube region, Danube-Tisza köze region and Tiszántúl region) and South Transdanubia (Somogy and Szekszárd). It has a fragmented distribution, especially in northeastern parts of the country (Soó 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 Makiš wetland) and Požarevac. In addition, the species has not been rediscovered since the second half of the last century in Fruška 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.
