Notes sobre algunes plantes rares o amenaçades als Pirineus catalans Authors Pere Aymerich i Boixader Abstract A number of data (chorological, demographic, ecological) about some plant species that are rare or threatened in the Catalan Pyrenees are reported. We outstand the information on Saponaria bellidifolia, of which we have studied the largest population in Western Europe, and also the data of one of the scarce Pyrenean populations of Salix hastata. For Sideritis bubanii, a narrow-endemic species, we provide the first detailed data about a population, including incidence of hybridization with S. hirsuta. For Gagea pratensis, a species with a wide distribution, we provide the second location in Catalonia. Downloads Download data is not yet available.
