ROSACE/E. 151 



Ilootstock woody, branchod, some of the divisions terminating 

 in tufts of loaves, others in flowerinij-stcms 1 to 2 feet liigli from 

 the centre of one of these tufts. Radical k\aves commonly with 2 

 ])air of leaflets besides the terminal one, which is a])proximate to 

 the upper pair, both pairs unequal at the base, with the outermost 

 side the lari;-est ; terminal leallet f to 2^ inches long. Stipules of 

 tiie radical leaves with the free portion entire, very small, those of 

 the stem-leaves with a large cut lici'liaccous portion. Flowers 

 rather few, white, f 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.

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- 

 natifld 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 

 IS inches long, simple below, corymboscly branched at the apex. 

 Leaflets \ to \\ inch long, very narrow, but widening out towards 

 the apex, with the sides nearly straight to the point where the 

 lobing commences. Flowers \ inch across, numerous, in a com- 

 pact or lax slightly irregular dichotomous cyme, with opposite 

 t<>rnate leaves or bracts at the forks. Calyx-segments oblojig-
