7.4x 3 Equisetum x litorale Kuhlew. ex Rupr.<br />
(E. arvense xfluviatile)<br />
Considering the dissimilarity of the habitat required by each<br />
parent this hybrid is surprisingly frequent. It is also extremely<br />
variable: in drier habitats specimens often approach E.arvense<br />
and in wet ones E.fluviatile (see J.G.Duckett & C.N.Page, in<br />
C.A.Stace (ed.), loc.cit.: 101; 1975).<br />
