Two new species of Galium (Rubiaceae) from the Iberian Peninsula

Two new species of the genus Galium are described from the Iberian Peninsula: G. moralesianum OrtegaOlivencia & Devesa, and G. talaveranum Ortega-Olivencia & Devesa. The first grows on limestone or dolomiticlimestone outcrops in south-east Spain (the Segura and Gador mountain ranges) and shows morphological similarities with G. boissieranum Ehrend. & Krendl, which is endemic to southern Spain (mountains of Malaga). The second inhabits the margins of water courses, alder stands and cork-oak dehesas (parkland-type systems) of the west of the Iberian Peninsula, and is morphologically reminiscent of G. mollugo L. The chromosome numbers of these two species and of G. boissieranum are given. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society, 2003, 143, 177–187.
