7.4 x 7 Equisetum X rothmaleri C.N.Page<br />

(E.arvense x palustre)<br />

A single small colony of this hybrid was found on the<br />

Trotternish peninsula, v.c. 104. It resembles a yellow-green<br />

E.palustre with a broader outline and more conspicuously<br />

angled branches.<br />

See C.N.Page, Watsonia 9: 229-237; '1973, and J.G.Duckett &<br />

C.N.Page, in C.A.Stace (ed.)loc. cit.; 102; 1975 for notes on<br />

both these hybrids.<br />

Similarly found on the Trotternish peninsula, v.c. 104, but as an<br />

extensive colony. It has the overall appearance of a narrower<br />

E.telmateia with cones on the vegetative shoots (as in<br />

E.palustre).<br />
