Orjen, numerical analyses. method and numerical analyses. Four floristically and ecologically well-defined groups of stands, representing different syntaxa, were identified, corresponding to Ključne besede: CANOCO, the sampling sites. The majority of stands represent dry eastern (sub)Mediterranean ekologija združb, varstvena biologija, rocky grasslands at different successional stages towards (sub)Mediterranean forest Hrvaška, Dalmacija, Črna gora, vegetation. Compared to the evolutionary and ecologically closely related and Orjen, numerične analize. sympatric S. officinalis, the morphologically easily distinguishable S. brachyodon differs in its flowering phenology and prefers relatively cooler, wetter, deeper and nutrient richer soils, which are developed on dolomite or dolomitic limestone at higher elevated sites. Despite its ability to cope with interspecific competition by means of clonal reproduction better than its congener, the populations are severely threatened by abandonment of traditional land use and by fires, making the species endangered (EN) according to IUCN criteria. Izvleček Na podlagi sigmatistične metode in s pomočjo numeričnih analiz smo proučevali ekologijo rastišč kratkozobe kadulje Salvia brachyodon (Lamiaceae), ozkega endemita vzhodnega Jadrana omejenega na zgolj tri nahajališča. Ugotovili smo štiri tipe sestojev, ki se floristično in ekološko dobro razlikujejo in se ujemajo z lokacijami rastišč.
