Summary
Djordjevic´ V. 2016. Epipactis muelleri (Orchidaceae-Neottieae), a species new to the flora of Serbia. – Phyton (Horn, Austria) 56(2): 303–312, with 2 figures.

Epipactis muelleri Godfery (Orchidaceae-Epidendroideae-Neottieae) was found on Mt Tara (western Serbia) for the first time in Serbia. This is currently the single known occurrence of this species in the Central Balkans, and the easternmost limit of its distribution in the Balkans, where it has recently been known only from two other countries (Slovenia and Croatia). Morphological characteristics, currently known distribution, and habitat preferences are indicated. In total, the two recorded populations comprise five flowering individuals. The current 2012-IUCN threatened status of E. muelleri in Serbia is estimated as Critically Endangered.
