& Delforge-Onckelinx, C. 2017.- Contribution to the knowledge of the Orchids of the Methana peninsula and the island of Poros (Saronic Gulf, Attiki, Greece)Natural. belges 98(Orchid.
A presentation of the geology, the geomorphology, the
climate, the vegetation, the human impact over the landscape of the
Methana peninsula and the island of Poros is provided. A review of the
past and present studies and research about their orchids is presented.
It appears that 20 orchids species were known for Methana peninsula
before 2014 (Table 1), and probably none for Poros. Research on Methana
in March and April 2014 has revealed 36 orchid species for the
peninsula, bringing their number up to 38 (Table 1). Research on Poros
has revealed 10 species for the island (Table 2). First mentions are
made in the Methana peninsula for Cephalanthera longifolia, Dactylorhiza romana, Herorchis boryi, H. picta var. skorpilii, Ophrys cephaloniensis, O. cerastes, O. cinereophila, O. crassicornis, O. hellenica, O. leucadica, O. mammosa, O. mycenensis, O. phryganae, O. punctulata, O. spruneri, O. taigetica, O. ulyssea, Orchis provincialis, O. quadripunctata, Paludorchis palustris var. elegans, Serapias parviflora, and Vermeulenia papilionacea var. aegaea.
After careful examination of “critical” plants as well as
photographies, published or not, it appears that old or recent mentions
of orchids, made for Methana, are questionable or erroneous. Mentions
of Anacamptis morio, Ophrys cornuta, O. fusca, O. lutea, O. oestrifera subsp. schlechteriana, O. tenthredinifera, and Orchis anatolica probably concern, respectively, Herorchis picta var. skorpilii, Ophrys cerastes, O. punctulata, O. sicula var. transadriatica, O. mycenensis, O. villosa, and Orchis quadripunctata. The species found on Poros in 2014 are Anacamptis pyramidalis var. brachystachys, Ophrys cinereophila, O. hellenica, O. leptomera, O. leucadica, O. mammosa, O. sicula var. transadriatica, O. villosa, Serapias bergonii, and Vermeulenia papilionacea var. aegaea.
A list of 36 species and 3 hybrids, and 41 distribution maps, based on
previous localizable records, published or not, and on the presence in
March and April 2014 in 51 utmwgs84 squares of 1 km × 1 km, are provided as well as a list of 93 sites prospected.
