The genusNigritella(Orchidaceae) in the Iberian Peninsula

[摘要] As a result of the revision ofNigritellaL.C.M. Richard in the Iberian Peninsula, here we recompile information of its variability, taxonomy, nomenclature and chorology. Two taxa are recognized:Nigritella austriacasubsp.iberica(Teppner & E. Klein) L. Sáez, comb. nov. andN. gabasianaTeppner & Klein, and the presence ofN. cornelianais excluded. Detailed phytodermologic analysis showed that size of guard cells is useful for species identification.
