dendroid habit of the type was gathered among rocks on Ben

in habit, has also been found on Quinag Hill, Skye, _ is certainly 
deserving of a varietal name.—E. striatum B. &S. 8.—E. rusci-

—P. denticulatum form which grew in tall seorenan 
bright green tufts, paler below, was common by springs and 
rivulets on Canisp and Quinag. The leaves are large, tapering 
to an almost acuminate point, and usually markedly denticulate at 
the apex, very decurrent, with long double nerves reaching near ly 
half the length of the leaf, and with large cells. The leaf-margin 
is also slightly recurved. iP ener B. & ;
