RESUMEN. Sobre el tratamiento de Galium L. (Rubiaceae) en Flora Iberica. El estudio taxonómico del género Galium para Flora Iberica ha revelado la existencia en el territorio de 51 especies y 14 subespecies. Éstas han sido agrupadas en 10 secciones, previamente descritas, reconociéndose para algunas de ellas nuevas series: Galium sect. Galium ser. Trichogaliopsis (Lange) Ortega-Olivencia & Devesa, Galium sect. Galium ser. Andalusiana Ortega-Olivencia & Devesa, Galium sect. Platygalium ser. Platygalium (DC.) Ortega-Olivencia & Devesa, Galium sect. Platygalium ser. Ephedrogalium Ortega-Olivencia & Devesa y Galium sect. Leiogalium ser. Pulchra Ortega-Olivencia & Devesa. La serie Ephedrogalium comprende sólo G. ephedroides Willk., taxón para el de se ha estudiado la anatomía foliar, al objeto de evidenciar el número de nervios que poseen sus hojas -tres- y que justifica su inclusión en la sección. Para Galium idubedae (Pau ex Debeaux) Pau ex Ehrend. (Galium sect. Leptogalium Lange) se describe una nueva variedad: Galium idubedae var. humile C. Vicioso ex Ortega-Olivencia & Devesa.
Palabras clave. Flora Iberica, Galium, Rubiaceae, taxonomía.
SUMMARY. Treatment of Galium L. (Rubiaceae) in Flora Iberica. A taxonomic study of the genus Galium has shown the presence of 51 species and 14 subspecies in Flora Iberica. These taxa are gathered in 10 previously known sections, and in some of them new series are recognized: Galium sect. Galium ser. Trichogaliopsis (Lange) Ortega-Olivencia & Devesa, Galium sect. Galium ser. Andalusiana Ortega-Olivencia & Devesa, Galium sect. Platygalium ser. Platygalium (DC.) Ortega- Olivencia & Devesa, Galium sect. Platygalium ser. Ephedrogalium Ortega-Olivencia & Devesa and Galium sect. Leiogalium ser. Pulchra Ortega-Olivencia & Devesa. Ser. Ephedrogalium only comprises G. ephedroides, a species where a study of the foliar anatomy has been carried. Its leaves show three nerves and that character justifies its inclusion into section Platygalium. Also, a new variety is described in G. idubedae (Pau ex Debeaux) Pau ex Ehrend. (Galium sect. Leptogalium Lange): Galium idubedae var. humile C. Vicioso ex Ortega-Olivencia & Devesa
Key words. Flora Iberica, Galium, Rubiaceae, taxonomy.
