Atropa pallidiflora is confined to the central part of a narrow belt of temperate rainforest fringing the Southern shore of the Caspian Sea, stretching (travelling from West to East) from the Talysh Mountains of the extreme Southeast of Azerbaijan through the Iranian provinces of Gilan, Mazandaran and Golestan and petering out in two spurs of woodland in Iran's North Khorasan province. The Northern spur ends near the village of Ghosha Tapeh and the Southern near the village of Havar and neither is far from the Kopet Dag range marking the border between Iran and Turkmenistan - where another Atropa species Atropa komarovii Blin.and Shalyt. (not currently an accepted species) is to be found. Viewed on Google Earth, this richly-forested region (the Shomal) stands out in deep green, contrasting sharply with the arid tones of the bulk of the Iranian plateau to the South, and it comes as no surprise to learn that it constitutes essentially a 'hotter spot' within the Irano-Anatolian biodiversity hotspot, namely the Northern edge of the Elburz Range forest steppe ecoregion - which is to say the North slope of the Alborz mountains - benefitting from the moisture from the Caspian Sea.
