The taxonomy of Galium crespianum J.J. Rodr. (Rubiaceae), a Balearic Islands endemic revisited

Abstract Galium crespianum J.J. Rodr. is a perennial plant inhabiting cliffs and crevices on the Balearic Islands. Although it was described from the mountains of Mallorca, several populations from the islands of Eivissa and Formentera have been traditionally considered as belonging to the same species. A careful comparison of specimens from the western and eastern Balearics revealed several discriminant features in gross morphology (robustness and habit of the stems, presence or absence of hairs at the internodes and leaves, waxiness of stems and leaves, shape of the inflorescence, flower colour and scent) and stem anatomy. In addition, several mutations in the ribosomal ITS sequences dist…

A new Biscutella (Brassicaceae) species from the western Balearic Islands

Abstract A new diploid species, Biscutella ebusitana is described from coastal cliffs of the western Balearic islands. It is related to B. sempervirens L. and B. montana Cav. from which it can be distinguished by a combination of vegetative (shape, size, petiole and hairs of leaves, petiolate leaves) and reproductive features (shape of inflorescence, calyx indument). Earlier Balearic records of B. frutescens Coss. should be referred to B. ebusitana .
