(E. arvense xfluviatile) Considering the dissimilarity of the habitat required by each parent this hybrid is surprisingly frequent. It is also extremely variable: in drier habitats specimens often approach E.arvense and in wet ones E.fluviatile (see J.G.Duckett & C.N.Page, in C.A.Stace (ed.), loc.cit.: 101; 1975). 4 6 6 5 4 3 2 1 0

interesting high mountain flush ecotype would be worth<br />

has the lowermost internodes of the branches characteristically<br />
