Chromosome numbers of severalLamiaceae from Spain
Chromosome numbers of twenty taxa, almost all of them Iberian endemics, of the generaTeucrium, Sideritis, Thymus andSalvia are reported. New chromosome numbers are given for the following taxa:Teucrium homotrichum (2n=78),T. hifacense (2n=26),T. rivasii (2n=26),T. rivas-martinezii (2n=26),Sideritis edetana (2n=30),S. murgetana subsp.littoralis (2n=28), and the hybridS. xviciosoi (2n=27). The first count on Iberian material forSalvia pratensis (2n=18) is reported. Chromosome numbers have been confirmed for the rest of the taxa studied on material from SE Spain. Karyotype analyses and taxonomic remarks are included.
Comparative analysis of biological and ecological differentiation of Anemone palmata L. (Ranunculaceae) in the western Mediterranean (France and Spain): an assessment of rarity and population persistence
The western Mediterranean geophyte Anemone palmata L. is one of the most endangered angiosperm taxa in France. The biological and ecological characteristics of French populations are contrasted with those of populations from near the centre of the species distribution in east Spain. A Correspondence Analysis discriminates the French and Spanish populations according to substrate and the composition of the plant communities where they grow. The karyological study reveals that east Spanish plants are autotetraploid, whilst the French are all diploid. In addition, morphological differences were registered, Spanish plants generally being more vigorous. French populations consist mostly of senil…
