Abstract

Numerous subfossil seeds of Epipactis palustris (L.) Crantz, and Dactylorhiza spp. (D. incarnata/maculata complex) found in early Holocene sediments in northern Poland are the first record of orchid seeds in geological formations of any age and location. Themacro- andmicromorphological characters of the seeds were examined to determine their taxonomic affinity. The seeds were found among numerous macroremains of aquatic and terrestrial organisms, which are distinct in effective buoyancy, enabling air andwater dispersal. The orchid populations developed in a floodplainmeadowwhere summer inundationwas probably among themain agents facilitating seed dispersal and deposition in lake sediments.We discuss potential environmental factors enabling the formation and preservation of the subfossil assemblages and suggest some technical issues among the reasons for the general poverty of orchid fossil data. Our data provide the first direct evidence for the early post-glacial establishment of populations of E. palustris and species of the D. incarnata/maculata complex in the northern part of Central Europe.
