Abstract

The identity of Asperula asperrima Boiss., a species usually misidentified, is discussed, and when transferred to the genus Galium it requires a new name, here proposed as G. pierredmondii. This species is described, illustrated and compared with its closest relatives in the genus Galium, namely G. boissierianum and G. moralesianum. While G. boissierianum lives exclusively on peridotites and G. moralesianum on limestones and dolomites, the ecological behaviour of G. pierredmondii is much broader, inhabiting peridotites, schists, limestones and dolomites; furthermore, G. pierredmondii is partially sympatric with the former, from which it may derive the confusion involving both species. Synonymy is revised for the concerned names, and an updated identification key is reported for the Iberian taxa of G. sect. Galium.
