The presence of different chromosome numbers in somatic cells within the same species was also observed in several genus of this family, such as in the case of Mentha (Ayyangar and Vembu 1985, Queiros 1985, Pogan et al 1986, Tyagi and Ahmad 1989, Ahmad et al 1992, Chambers and Hummer 1994, Origanum (Gill 1984, Ayyangar and Vembu 1985, Wentworth et al 1991 and Minthostachys (Alkire et al 1994, Ordóñez et al 2002, and genera Hedeoma is not an exception.…”

Hedeoma multiflorum (Lamiaceae) commonly known as tomillito de las sierras is a native aromatic herb used in folk medicine for its stimulant and digestive properties. Plants are collected in the wild; their uncontrolled exploitation exceeds their rate of natural regeneration leading to the risk of genetic erosion. The aims of this work were to determine the chromosome number of three populations of Hedeoma multiflorum native to Córdoba (Argentina) and characterize them from the meiotic point of view. Most of the somatic cells observed showed the chromosome number 2n=72. In relation to their meiotic behavior, irregularities as presence of univalent, laggards, micronucleus and occurrence of cytomixis were observed. The characterization of the native germoplasm of this valuable aromatic and medicinal species is fundamental to achieve its sustainable handling and conservation.
