A New Coastal Species of Limonium (Plumbaginaceae) from Southeastern Spain

摘要

A new species, Limonium scopulorum (Plumbaginaceae), is described from the maritime cliffs of Alicante province, Spain (southeastern part of the Iberian Peninsula). This new taxon belongs to the group of Limonium delicatulum, which is highly diversified in the Mediterranean territories of the Iberian Peninsula. It is related to the Balearic species L. biflorum, though several leaf, floral and chromosomal features warrant its easy recognition. Molecular divergence, shown in previous studies, also supports its separate treatment. Major affinities and differences with other related taxa are discussed. Moreover, morphological, ecological, chorological, biogeographic features of the new taxon are discussed, and its conservation status is reported. An identification key is provided for Spanish taxa of the Limonium delicatulum group.
