P. salisburgensis, Henke, and maculata, Pourr., which were published in 
the same year, and P. rubens, Vill., the earliest of all. ] 
 6..P. Sibbaldi, Haller f. (fig. 318). Sibbaldia.—The Ae 
stock forms a short, dense, spreading tuft. Leafstalk seldom above 6 
lines long, with 3 obovate or wedge-shaped leaflets, 3-toothed at the 
end, green, and more or less hairy on both sides. Flower-stems $ to 14 
inches long, almost leafless, bearing a cyme of small flowers, of which 
the green calyxes are the most conspicuous, the petals being very small 
and of a pale yellow, or occasionally wanting. ‘The carpels are 5 to 7, 
rarely more. The lobes of the calyx often close over the carpels after 
flowering, but the latter are not enclosed within the tube as in Alche- — 
milla. (Sibbaldia procumbens, Linn.) 
In the mountains of northern and Arctic Europe, Asia, and America, © 
or at greater elevations, in the higher ranges of central Europe and 
Asia, Frequent in the Scotch Highlands, constituting in some places 
a considerable portion of the greensward, but unknown in England or 
Ireland, Fl. summer. 
7. P. fruticosa, Linn. (fig. 319). Shrubby P.—Differs from all other 
European species by the stem, the lower portion of which becomes 
woody, forming an erect or spreading shrub or undershrub often 
very low, but sometimes attaining 2 feet in height; the short flower- 
ing branches die down as in other Potentilas. Stipules narrow and 
thin. Leaflets usually 5, narrow and entire; the three upper ones 
often shortly connected at the base; the two lower inserted at some 
distance from them, so as to form a pinnate rather than a digitate leaf. 
Peduncles terminal or opposed to the leaves, each with a single rather 
large yellow flower. 
In bushy or stony places, chiefly in mountain districts, widely diffused 
over Kurope, central and Russian Asia, and North America, but not 
generally common. In Britain, only in a few localities in the north of 
England, and in Clare and Galway in Ireland. Fl. summer. 
8. P. anserina, Linn. (fig. 320). Silver-weed.—Stock tufted, with 
long creeping runners rooting at the nodes, as in P. reptans. Leaves 
pinnate, with numerous oblong, deeply toothed leaflets, green or some- 
what silky on the upper side, of a shining silvery white underneath 
from the silky down with which they are covered. Peduncles long, 
solitary at the rooting nodes, bearing a single rather large yellow 
flower. 
Common on roadsides, in stony pastures, and waste places throughout 
Europe, Russian and central Asia, and a creat part of North America, . 
extending to the Arctic regions, and reappearing in the southern hemi. 
sphere. Abundant in Britain. Fl. summer. 
9, P. rupestris, Linn. (fig. 321). Rock P.—Stock perennial, some- 
times forming a very short, woody stem, the annual flower-stems 6 to 
10 inches high, Leaves chiefly radical, pinnate; the common stalk — 
rather long ; the leaflets 5 or rarely 7, ovate, toothed, green, and some- 
what glutinous. The stem-leaves few and smaller, usually with only 3 
leaflets. Flowers few, rather large, of a pure white, forming a loose, | 
irregular corymb. 
In clefts of rocks, in limestone districts, in the mdintedmuateiaeea of 
central and southern Europe, and across the whole continent of Asia, — 
extending northwards into southern Sweden. In Britain, only in one
