Resumo<br />
1. A presente lista de plantas vasculares dos arquipélagos<br />
da Madeira e das Selvagens resulta da compilação de<br />
informação publicada em obras e artigos de referência.<br />
2. O critério taxonómico e nomenclatural é o seguido pela<br />
Flora Ibérica (Castroviejo et al. 1986 -2008) e pela Flora <strong>of</strong><br />
Madeira (Press & Short 1994).<br />
3. Nos arquipélagos da Madeira e Selvagens contabilizam-<br />
-se 1204 taxa (espécies e subespécies) de plantas vasculares.<br />
Destes, 154 (a que correspondem 136 espécies<br />
e 21 subespécies) são endemismos dos arquipélagos<br />
da Madeira e Selvagens (12,8%), 74 são endemismos<br />
macaronésicos (6,1%), 480 são taxa nativos (39,9%), 66<br />
são nativos prováveis (5,5%), 29 são introduzidos prováveis<br />
(2,4%) e 401 são taxa introduzidos (33,3%).<br />
4. Nos arquipélagos da Madeira e Selvagens dominam<br />
as Magnoliopsida (863 taxa), seguidas das Liliopsida<br />
(260), Filicopsida (65), Pinopsida (6), Lycopodiopsida<br />
(5), Ophioglossopsida (3), Equisetopsida (1) e Gnetopsida<br />
(1).<br />
5. A ilha da Madeira apresenta 94,4% do total de taxa e<br />
89,6% do total dos endemismos dos arquipélagos da<br />
Madeira e das Selvagens, enquanto as Selvagens apresentam<br />
a menor proporção, com apenas 8,7% do total<br />
de taxa e 8,4% dos endemismos.<br />
6. No que diz respeito às ilhas habitadas da Macaronésia,<br />
a ilha da Madeira é terceira com maior número de endemismos<br />
exclusivos (94) e a segunda em densidade de<br />
endemismos exclusivos.<br />

Abstract<br />
1. The present list <strong>of</strong> <strong>the</strong> vascular plants <strong>of</strong> <strong>the</strong> Madeira <strong>and</strong><br />
Selvagens <strong>archipelagos</strong> results from data published in<br />
key scientific works.<br />
2. Taxonomic <strong>and</strong> nomenclatural criteria follow <strong>the</strong> Flora<br />
Ibérica (Castroviejo et al. 1986 -2008) <strong>and</strong> <strong>the</strong> Flora <strong>of</strong><br />
Madeira (Press & Short 1994).<br />
3. 1,204 taxa (species <strong>and</strong> subspecies) <strong>of</strong> vascular plants<br />
are reported from <strong>the</strong> <strong>archipelagos</strong> <strong>of</strong> Madeira <strong>and</strong> Selvagens.<br />
Of <strong>the</strong>se, 154 taxa (which refer to 136 species<br />
<strong>and</strong> 21 subspecies) are endemic to <strong>the</strong> <strong>archipelagos</strong> <strong>of</strong><br />
Madeira <strong>and</strong> Selvagens (12.8%), 74 are Macaronesian<br />
endemics (6,1%), 480 taxa are native (39.9%), 66 are<br />
“possible natives” (5.5%), 29 are “possible introduced”<br />
(2.4%) <strong>and</strong> 401 taxa are introduced (33.3%).<br />
4. In <strong>the</strong> <strong>archipelagos</strong> <strong>of</strong> Madeira <strong>and</strong> Selvagens <strong>the</strong> Magnoliopsida<br />
(863 taxa) are dominant, followed by Liliopsida<br />
(260), Filicopsida (65), Pinopsida (6), Lycopodiopsida<br />
(5), Ophioglossopsida (3), Equisetopsida (1) <strong>and</strong> Gnetopsida<br />
(1).<br />
5. Madeira Isl<strong>and</strong> comprises 94.4% <strong>of</strong> <strong>the</strong> total taxa <strong>and</strong><br />
89.6% <strong>of</strong> <strong>the</strong> endemics from <strong>the</strong> <strong>archipelagos</strong> <strong>of</strong> Madeira<br />
<strong>and</strong> Selvagens, while <strong>the</strong> Selvagens have <strong>the</strong> lowest<br />
proportion, with only 8.7% <strong>of</strong> total taxa <strong>and</strong> 8.4% <strong>of</strong> endemics.<br />
6. In what concerns <strong>the</strong> inhabited isl<strong>and</strong>s <strong>of</strong> Macaronesia,<br />
Madeira Isl<strong>and</strong> has <strong>the</strong> third highest number <strong>of</strong> exclusive<br />
endemics (94) <strong>and</strong> <strong>the</strong> second highest density <strong>of</strong> exclusive<br />
endemics.
