Infrasectional systematics of the genus Sideritis L. section Sideritis (Lamiaceae)

Abstract

A new taxonomic division of the section Sideritis is proposed on the basis of morphological, cytological and chemical characters. The following subsections are recognized: Grandiflora, Ovata, Camarae, Linearifolia, Gymnocarpae, Stachydioides, Lacaitae, Hirsuta, Chamaedryfolia, Arborescens, Flavovirens, Leucantha, Angustifolia, Serrata and Scordioides. Possible evolutionary pathways are discussed.
