Totals<br />

139 families <strong>of</strong> vascular plants are reported for <strong>the</strong> <strong>archipelagos</strong><br />

<strong>of</strong> Madeira <strong>and</strong> Selvagens. The Poaceae, Asteraceae<br />

<strong>and</strong> Fabaceae have <strong>the</strong> highest number <strong>of</strong> taxa<br />

<strong>and</strong> altoge<strong>the</strong>r amount to 32.5% <strong>of</strong> total taxa. In fact, 20%<br />

<strong>of</strong> <strong>the</strong> families comprise 75.5% <strong>of</strong> plant taxa (Fig. 1). The<br />

number <strong>of</strong> plant genera is 577, <strong>of</strong> which <strong>the</strong> richest in taxa<br />

are Trifolium L. (25), Vicia L. (15), Juncus L. (13), Plantago<br />
