Geographic distribution of 20 chamomiles (Matricariachamomilla L.) populations, surveyed and collected in nine districts of Albania, and their comparison with 19 ex situ data of chamomile populations was carried out. The geographic areas, separated into grid cells of 1 x 1 km, and 10 x 10 km was used to assess the geographic distribution, richness and the representativeness of chamomile samples in ex situ collection. Spatial analysis detects areas of high diversity of chamomile population surveyed were Berat and Fieri districts. Comparative analysis of the representativeness indices found that chamomile populations surveyed and collected in other district areas have contributed directly in increasing their representativeness in the ex situ collection of chamomile samples. Highest contribution in increasing the representativeness of chamomile samples in ex situ collection was found in Berat, Fieri and Korca district areas, as in these areas chamomile populations were surveyed and collected far than 10 km from ex situ present points, and mid representativeness contribution was found in Dibra, Lezha and Shkodra districts areas. For the chamomile populations surveyed in Tirana, Durres and Vlora district areas a full representativeness status in ex situ collection of genebank was found. In total there were more than 70% of surveyed point that contributes with chamomile samples collected in new areas, never collected before by any collecting mission.
