Abstract

Some ecological, caryological and systematic data on Nepeta foliosa Moris. – Nepeta foliosa is a rare Sardinian endemic species, which lives at an altitude of 1200 m, on the Oliena calcareous mountains in Central Sardinia. Its somatic chromosome number is 2n = 36. From a taxonomical point of view, N. foliosa appears a well isolated species within the Nepeta section, where recently Turner placed it. It shows affinity with species of the Pycnonepeta Benth. section, and particularly with Nepeta multibracteata Desf. For this reason it is here proposed to transfer N. foliosa into the Pycnonepeta section.
