Biosystematic study of the subsection Thymastra (Nyman ex Velen.) R. Morales of the Thymus L. genus (Lamiaceae)

Abstract The interest to revision of the Thymus genus in the southern western Iberian peninsula is important to comprehension of the taxonomy and evolution process in the genus. Biosystematic study of the subsect. Thymastra (Nyman ex Velen.) R. Morales of the Thymus genus revealed the existence of two new subspecies: Thymus camphoratus subsp. congestus subsp. nov. and Thymus capitalletus subsp. anomalus subsp. nov., and a new variety: Thymus camphoratus subsp. camphoratus var. grandiflorus var. nov. Also are typified all the taxa associated to the subsection Thymastra (Nyman ex Velen.) R. Morales.
