Mt Kuh-e Siah of Lendeh in Dehdasht (Kohgiloyeh and Boyer Ahmad Province, SW Iran) is part of the Zagros Mountain Range with amplitude from 1000 m to 3000 m a.s.l. Floristic characteristics and vegetation structure of the mountain were surveyed during the growing seasons of 2011 and 2012. Altogether, 282 vascular plant taxa belonging to 198 genera and 65 families were identified in the area. Asteraceae and Fabaceae were the species-richest families. A floristic analysis indicated that hemicryptophytes were the predominating life forms in that mountain. Moreover, from phytogeographical point of view and despite the area’s closeness to the Saharo-Sindian and Saharo-Arabian phytogeographical regions, Irano-Turanian elements were the dominant chorotype in the flora of the area. More importantly, 32 Iranian endemic species and 38 threatened plant taxa existed in that region. As the area is one of the least known and inaccessible points of the Zagros oak woodlands, the result of the current study could serve as a scientific backbone for biodiversity conservation of these important ecosystems.
