Abstract
73 new references for 72 taxa of vascular plant are here reported for the Madeira archipelago. 55 not previously recorded for Desertas Islands, 12 to Porto Santo Island and 6 for Madeira Island. Of the 72 taxa, 28 are xenophytes, and 10 are new taxa to the flora of the archipelago (of these 9 are xenophytes). Their native status, taxonomy and distribution are briefly discussed.
Highlights
The Madeira archipelago is located in the NE Atlantic, about 795 km SW of mainland Portugal, between latitudes 32o 24’N and 33o 07’N and longitudes 16o 16’W and 17o 16’W
Porto Santo Island, with an age of approximately 14 Ma is much older than Madeira Island (< 7 Ma) (Ramalho et al 2015), and much lower with a smoother orography resulting from an intense erosion process
Results are based on specimens collected in the Madeira archipelago, including Madeira Island, Porto Santo and its islets, and the Desertas islands
Summary
The Madeira archipelago is located in the NE Atlantic, about 795 km SW of mainland Portugal, between latitudes 32o 24’N and 33o 07’N and longitudes 16o 16’W and 17o 16’W. Common native nitrophilous species in Madeira and Porto Santo (Jardim & Menezes de Sequeira 2008), reported for the first time to Deserta Grande. Native to Madeira and Porto Santo Islands (Jardim & Menezes de Sequeira 2008), was found for the first time at Deserta Grande.
