COSTA, José Carlos et al. The scrubland of limestone-derived decarbonated soils of the Western Iberian Peninsula. Finisterra [online]. 2021, n.118, pp.73-91.  Epub 01-Dez-2021. ISSN 0430-5027.  https://doi.org/10.18055/finis18502.

In the present article, the proposal of a new suballiance, Lavandulo luisieri-Cistenion albidi, is presented, constituted by chamaephytic and nanophanerophytic communities in eroded decarbonated soils derived from limestones (leptosols, chromic luvisols and cambisols) in the dry to lower hyperhumid, thermo-mesomediterranean bioclimatic levels. It is distributed throughout the western Iberian Peninsula in the Coastal Lusitan-Andalusian and Lusitan-Extremadurean biogeographical territories. It is positioned in the Ulici argentei-Cistion ladaniferi, Lavanduletalia stoechadis, Cisto-Lavanduletea. The new associations Anthyllido maurae-Ulicetum jussiaei, Sedo albi-Cistetum crispi and Thymetum congesti are also described. The multivariate analysis confirmed the segregation of this new suballiance, as well as the new associations.
