Résumé :	Orophilous taxa of Sideritis sect. Sideritis (Lamiaceae) are rare, although highly diversified in south-eastern Spain. Most of them belong to subsections Hyssopifolia and Fruticulosa and show very reduced distribution areas in the summits of the highest Betic mountains. The inaccessibility of their habitats has meant that many of them have been described only within the last twenty years. In this context, a new species Sideritis tugiensis is described in subsection Hyssopifolia, from the Oromediterranean summits of Sierra de Segura (south-eastern Spain). It is a woody, cushion-shaped plant, resembling both S. carbonellis Socorro (subsect. Hyssopifolia) and S. glacialis Boiss., s.l. (subsect. Fruticulosa), though important morphological divergences warrant recognition at species rank. Data on morphology, ecology and chorology of the new species are reported, and affinities and differences with regard to close taxa from other subsections are presented. Evolutionary trends in the whole aggregate are briefly discussed.
