GLASS XII. ORDER III.] POTENTILLA. 743 



leafy, and more or less clothed with long horizontal hairs. Root-leaves 

 numerous, with long petioles, hairy, leaflets seven, linear, wedge-shaped, 

 deeply and distantly serrated to near the base, dark green, paler be- 

 neath, scattered over with hairs, the terminal tooth much shorter than 

 the others, the stem-leaves sessile, on short stalks, ternate. Stipules all 

 oblong, lanceolate, the radical ones thin, brown, membranous. Flowert 

 mostly numerous, axillary, and in terminal panicles, the stalks long, 

 round, slender, hairy. Calyx hairy, the outer alternate segments 

 linear, as long as the inner ovate ones. Petals broad, heart-shaped, 

 yellow, orange colour towards the base. Carpels smooth, or more or 

 less rugose. 



Habitat. Hills of Clove and Braes of Balquidder, Scotland. Mr. 

 D. Don. 



Perennial ; flowering in June. 



This species is distinguished from P. verna by its stouter habit, and 

 the leaflets coarsely serrated to near the base. It is not unfrequent on 

 the mountains of Switzerland and France. 



8. P. al'ba, Linn. (Fig. 844.) White Cinque-foil. Stem slender 

 procumbent; radical leaves with five oblong leaflets, silky beneath, 

 and serrated towards the apex, with slender incurved teeth ; carpels 

 smooth.

Root long, woody, branched, almost black. Stems several, slender, 

 filiform, procumbent, somewhat branched and leafy, clothed with slen- 

 der spreading hairs. Root-leaves numerous, with long slender hairy 

 footstalks, leaflets five, oblong lanceolate, tapering towards the base 

 smooth and green above, white and silky beneath, with close shining 

 hairs, the margin serrated towards the point, with slender incurved 

 teeth, the stem-leaves with a short footstalk, and three narrow oblong 

 leaflets. Stipules oblong lanceolate, with an attenuated point. Flowers 

 seldom more than three or four, with slender peduncles. Calyx hairy 

 the outer segments linear, shorter than the inner lanceolate ones. 

 Petals white, oblong, heart-shaped, yellow at the base. Receptacle 

 hairy. Carpels slightly rugose. 



Habitat. Wales (?) Mr. Haviland (Hudson). 



Perennial ; flowering in June and July. 



This elegant little plant, we fear, has but slender claims to a place 

 in our British Flora, as it does not appear to have been found since 

 Hudson's time. It occurs on the mountains of Switzerland and 

 Germany, but not very common. 



9. P. rep' tans, Linn. (Fig. 845.) Common Creeping Cinque-foil. 

 Stem filiform, creeping, round, simple, rooting ; leaves quinate ; leaflets 

 oblong, wedge-shaped, deeply serrated, three toothed at the extremity 

 hairs close pressed; peduncles solitary, axillary.
