ROSACEA. 151 
Rootstock woody, branched, some of the divisions terminating 
in tufts of leaves, others in flowering-stems 1 to 2 feet high from 
the centre of one of these tufts. Radical leaves commonly with 2 
pair of leaflets besides the terminal one, which is approximate to 
the upper pair, both pairs unequal at the base, with the outermost 
side the largest ; terminal leaflet # to 2} inches long. Stipules of 
the radical leaves with the free portion entire, very small, those of 
the stem-leaves with a large cut herbaceous portion. Flowers 
rather few, white, $ to 1 inch across. Plant sparingly hairy below, 
more so above, densely so on the pedicels and calyces. 
This species is very unlike any of the other European forms of 
Potentilla.

Pirate CCCCXXXV. 
Stem ascending, tomentose. Radical leaves (as well as the lower 
and middle stem-leaves) stalked, digitate, with 5 narrowly wedge- 
shaped leaflets ; leaflets entire at the base, coarsely serrated or pin- 
natifid in the apical half, with the extreme margins reflexed, hoary- 
white beneath ; uppermost stem-leaves sessile, ternate, with linear- 
elliptical leaflets. Stipules with the free portion long, narrowly 
triangular, entire. Flowers in dichotomous cymes. Outer calyx- 
segments nearly as long as the inner, but narrower. Petals yellow, 
not much longer than the calyx, obovate, nearly entire. Recep- 
tacle hairy. Carpels glabrous, smooth. 
On dry gravelly pastures and by roadsides. Rather rare. 
Pretty generally distributed in England, but in Scotland confined 
to the East coast, in which it is found in scattered localities as far 
North as Moray. Not included in Professor Dickie’s Flora of 
Ulster, but marked in Dr. Moore’s list of Irish plants. 
England, Scotland, Ireland. Perennial. Summer and 
Autumn. 
Rootstock woody, producing few or numerous stiff stems, 6 to 
18 inches long, simple below, corymbosely branched at the apex. 
Leaflets 4 to 14 inch long, very narrow, but widening out towards 
the apex, with the sides nearly straight to the point where the 
lobing commences. Flowers 4 inch across, numerous, in a com- 
pact or lax slightly irregular dichotomous cyme, with opposite 
ternate leaves or bracts at the forks. Calyx-segments oblong-
