Specimens of this plant, which I have lately gathereil in various pa rts o f th e mountains of
Savoy and Switzerland, agree in every respect with those o f our own country: so th a t, a lthough I
have never yet had the good fo rtu n e to meet with its fructification, I venture to describe it as a new
species, thin k in g myself fully justified in so doing by the constancy o f the characters he re laid
down. At first sight, J. orcadensis m ig h t be mistaken for a variety of J . barhaia; b u t it will soon
be seen, th a t, in the pre sent species, the stipules are wholly wanting, and th a t the leaves are never
trifid. From J . venlricosa it differs in its la rg e r size, in the small obtuse notch o f th e leaves, and
in its erect mode o f g row th ; and from th a t, and every species to which it is in o the r respects a t all
allied, by the curiously recurved margins o f its leaves.
1 have taken its name from th e country in which it was first found.
