Asperula suberosa is a local endemic of Mt Athos, growing in crevices of limestone cliffs at (1200–)1600–2000 m. When illustrated in Flora Graeca (Plate 123. 1813) it was reported “in rupibus excelsis”, without specified locality, but the type was undoubtedly collected by Sibthorp and Bauer when climbing Mt Athos on 11 August 1787; cf. also Helichrysum sibthorpii (Plate 4: 6). Asperula suberosa is related to other local and regional endemics such as A. idaea and A. suffruticosa.
