Chromosome numbers of twenty taxa, almost all of them Iberian endemics
, of the genera Teucrium, Sideritis, Thymus and Salvia are reported. N
ew chromosome numbers are given for the following taxa: Teucrium homot
richum (2n=78), T. hifacense (2n=26), T. rivasii (2n=26), T. rivas-mar
tinezii (2n=26), Sideritis edetana (2n=30), S. murgetana subsp. littor
alis (2n=28), and the hybrid S. xviciosoi (2n=27). The first count on
Iberian material for Salvia pratensis (2n=18) is reported. Chromosome
numbers have been confirmed for the rest of the taxa studied on materi
al from SE Spain. Karyotype analyses and taxonomic remarks are include
