Taxonomy and distribution of the genus Rubus (Rosaceae) series Radula on the Iberian Peninsula

Monasterio-Huelin. E. 1995. Taxonomv and distribution of the genus Rubus (Rosaceae) series Radulu on the Iberian Peninsula. — Nord. J. Bot. 15: 365–373. Copenhagen. ISSN 0107–055X.
The majority of european batologists currently interpret the ser. Radula in a sense different from that given by its original author. According to the modem concept, this series is separated into two, distinguished by the leaflets felted beneath (ser. Radula ) versus not felted (ser. Pallidi ). Following this criterion, we include 7 species in ser. Radula , one of which ( R. pauanus ) is described as new, and provide a photograph of the holotype, an analysis of pollen, and a distribution map. Also provided are keys to the series of the subgenus Rubus and to the species of the ser. Radula , and a comparative study from a morphological and biogeographical perspective of all species which comprise this series on the Iberian Peninsula.
