| Abstract: | A new species of Achillea L., Achillea occulta Constantin. & Kalpoutz., from the summit area of Mount Koulochera in south-east Peloponnisos, Greece, is described and illustrated. It belongs to A . sect. Ptarmica and further, to a small group of taxa known under the illegitimate sectional name 'Anthemoideae'. In Greece, A. occulta has no close allies. The taxonomically related taxa, i.e. A. barrelieri (Ten.) Sch. Bip., A. mucronulata Bertol., A. oxyloba (DC.) Sch. Bip. and A. schurii Sch. Bip. are found in the Italian Peninsula, the Alps and the Carpathians. Phytogeographically, the finding of a species with such taxonomic connections in south-east Greece was unexpected. The new species grows in semi-shade, often hidden in suitable limestone rock hollows and the foot of rocks, together with several other Greek endemics. Its chromosome number of 2 n = 18, counted in root tips, is also reported and illustrated. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 147 , 249–256. |
