lav09 | Brullo et al. (1997: 34-35) described the Alyssion euboaei, an alliance that was typified by a very dubious ‘forest’ association (see Mucina & Dimopoulos 2000 for details), rendering their alliance name (and concept) a nomen dubium. Here I suggest that the phrygana on ultramafic substrates studied for instance, by Krause et al. (1963) and L. Mucina (unpubl.), is floristically, ecologically and biogeographically different (high number of local ultramafic endemics) and deserves recognition as an alliance in its own right. Therefore, I introduce the name Odontarrheno euboeae-Lavandulion stoechadis all. nov. hoc loco and I typify this alliance by assigning the Fumano pintazii-Lavanduletum stoechadis Mucina et Dimopoulos ass. nov. hoc loco as the holotypus hoc loco. The holotypus (hoc loco) of the latter association is the following relevé extracted from my unpublished report: Hellas, Evvia (Euboea) Island, Limni, SE of town, 20 June 1999 (rel. made by L. Mucina; the sampling scale used: Barkman et al. 1964); alt. 535 m, aspect: 33°, slope: 30°, vegetation cover: 100%; cover litter: 95%; dense phrygana/garrigue on ultramafic peridotite. Lavandula stoechas 2b, Sarcopoterium spinosum 2b, Fumana pinatzii 2m, Hypochaeris achyrophorus 2m, Linum strictum 2m, Trachynia distachya 2m, Anthyllis hermanniae 1, Centaurea laureotica 1, Alyssum euboeum 1, Filago gallica 1, Misopates orontium 1, Aira elegantissima +, Allium sp. +, Asterolinon linum-stellatum +, Carlina corymbosa +, Convolvulus elegantissimus +, Hypericum empetrifolium +, Jurinea consanguinea +, Phillyrea latifolia +, Helictochloa bromoides +, Sarcopoterium spinosum +, Teucrium capitatum +, Thesium bergeri +, Thymelaea tartonraira +, Alkanna graeca subsp. baeotica r. This alliance encompasses the ultramafic phrygana of Evvia Island as well as the adjacent mainland of the Sterea Hellas region. The diagnostic species of the alliance are Alkanna graeca subsp. baeotica, Alyssum densistellatum, Centaurea ebenoides, C. laureotica, Erica manipuliflora, Fumana pinatzii, Hypericum empetrifolium, Jurinea consanguinea, Lavandula stoechas, Odontarrhena euboea, Onosma graeca, Thymus atticus and T. teucrioides subsp. candilicus.
