F ir s t observed by tlie late Mr. John Mackay on Breeze
Hill, Isle of Skye, in 1794. Sir James Edward Smith has
noticed it in English Flora as a variety of A. dioica ; but after
many years observation, and an attentive comparison of it,
cultivated together with A. dioica and plantaginea, I am
now fully satisfied of its being entitled to rank as a species.
It approaches much nearer to A.plantaginea than to A.di-
oica ; but it is essentially distinguished from both by its uniform,
spathulate leaves, densely clothed on both sides with
permanent down. Plant forming a dense, flat patch. Shoots
leafy, half an inch or an inch long. Stems upright, simple,
filiform, leafy, very downy, from 2 to 4 inches high, bearing
3 or 5 flowers. Leaves scarcely an inch long, spathulate,
blunt, flat, coriaceous, thickly clothed on both sides with
a permanent, short, woolly, white down; those of the stem
narrow, strap-shaped, blunt, erect, sometimes adpressed,
downy and white on both sides, about half an inch long.
