Kozuharova, E., Panayotov, M. & Spadaro, V.: Autecology and ex situ growth of Leontopodium nivale subsp. nivale (Asteraceae) from North Pirin marbles (SW Bulgaria). — Fl. Medit. 28: 187-206. 2018. — ISSN: 1120-4052 printed, 2240-4538 online. Leontopodium nivale subsp. nivale is a local and disjunct endemic of the central Apennines in Italy and the Pirin Mountains in Bulgaria. The aim of this study is to investigate in situ microhabitat specifics and ex situ ontogenesis regarding the possible future cultivation and to evaluate hazards for wild populations in conditions of human impact and climate change. Leontopodium nivale subsp. nivale is stenobiont which is difficult to grow ex situ and t…
