16.2 x 1 Polypodium X mantoniae Rothm.<br />
(P.interjectum x vulgare)<br />
This hybrid can be recognized by its vigour, often forming large<br />
clones; morphologically it is intermediate between the parents.<br />
Frequent throughout Britain but less so in Ireland. <strong>The</strong> density<br />
of records for this hybrid in north and south-west Wales reflects<br />
concentrated field-work and its apparent scarcity elsewhere may<br />
not be a biological reality.<br />
