[eng] This paper provides chorological data for 30 taxa of the Balearic flora. Of these, four are new to the islands' flora: Arisarum x aspergillum Dunal, Guizotia abyssinica (L. fil.) Cass., Ornithogalum baeticum Boiss. i Rorippa palustris (L.) Besser. Three others are insular novelties: Amaranthus powelli S. Watson, Glycyrrhiza glabra L. i Crassula muscosa L. In addition, we provide data on other taxa, most of which represent important extensions of the known distribution area to the island of Mallorca. It should be noted that more than 40% of the records correspond to taxa of allochthonous origin.
