A new association of perennial nitrophilous vegetation from North-Western Iberian Peninsula

AbstractA new phytosociological association of perennial nitrophilous vegetation is described from submediterranean mountain areas of North-Western Iberian Peninsula. Geranio lusitanici-Scrophularietum herminiiass. nova (class Artemisietea vulgaris) is physiognomically predominated by Scrophularia herminiiand its individuality is based on the two nominal taxa (Scrophularia herminiiand Geranium pyrenaicumsubsp. lusitanicum), both endemic to the North-Western Iberian Peninsula. In this paper, the new association is fully characterised and distinguished from other perennial nitrophilous vegetation types in the territory in terms of its floristic composition, synecologic requirements, syntaxonomy, chorology and biogeography.
