The paper presents two new localities of Orchis pallens in the Chełm mesoregion (Silesian Upland, S Poland), found in 2014 in the vicinity of Ligota Dolna and Oleszka villages in Opole Province. The species occurs in overgrowing xerothermic grassland communities (Koelerio-Festucetum rupicolae, Origano-Brachypodietum pinnati, Origano-Vincetoxicetum hirundinariae). The populations consisted of 4 flowering individuals in Oleszka and 49 (34 flowering) in Ligota Dolna, with slight seasonal fluctuation. The main threats to the newly found localities of Orchis pallens are succession processes in xerothermic grassland communities. Active nature protection employing measures such as mowing or shrub removal is required.
