CLASS XII. ORDKR HI.] POTENTILLA. 741 



Stipules ovate, with an attenuated point, entire, rarely toothed. 

 Flowers small, yellow, mostly numerous. Calyx woolly, its segments 

 nearly equal. Petals scarcely longer than the calyx, ovate, notched. 

 Receptacle hairy, bearing numerous carpels, kidney^shaped, smooth, 

 and even. 



Habitat. Dry banks, pastures, and road sides, especially in a 

 gravelly soil. 0. Middleton Teesdale, Yorkshire. 



Perennial ; flowering in June and July. 



The variety 0. Guntherinna is remarkable in the stem being longer, 

 stouter, and more spreading, and much divided from the middle, or 

 below that in a paniculated manner, and the leaflets are more deeply 

 cat wilh narrower segments. We have some doubts of its being, how- 

 ever, more than a variety of P. argentea ; and as such we have for the 

 present followed De Candolle in retaining it, until further oppor- 

 tunities occur of observing its habit, &c. 



5. P. ver'na, Linn. (Fig. 841 ) Spring Cinque-foil. Stem declining; 

 root leaves with long hairy petioles ; leaflets five or seven, obovate, 

 wedge-shaped, acutely serrated or crenated, the terminal one shortest, 

 furrowed with veins above, smooth or hairy, as well as the margins and 

 under side; lower stipules linear, the upper ovate; carpels slightly 

 rugose.

Koch. Flora Germanicse et Helveticae, p. 217. " P. pusilla, Host" 



Root long, branched, and woody, brown, scaly above, Stems mostly 

 numerous, curved at the base, and spreading in a circular manner 

 from two to four or six inches long, sometimes rooting, round, branched 

 and clothed with silky hairs, spreading in the lower part, short and 

 close above. Leaves numerous, the radical ones on long slender round 

 hairy footstalks, leaflets five or seven, ovate, wedge-shaped, serrated 

 above the middle, with four serratures on each side, and the terminal 

 one shorter, the teeth acute, or obtuse, the outer leaflets mostly ob- 

 liquely ovate, and more deeply serrated on the outer side, green on 

 both sides, though darker on the upper, and furrowed with branched 

 veins, mostly smooth above, or hairy, as well as the under side, which 

 is mostly fringed on the margins and ribs with longer silky spreading 

 hairs, the leaves in the lower part of the stem nearly sessile, of three 

 narrower leaflets, in the upper part sessile, and mostly simple. Stipules 

 united to the footstalk, the lower ones narrow, awl-shaped, the upper 

 ovate. Flowers from three to six, on long round slender hairy pedicles, 

 from the upper part of the stem. Calyx clothed with spreading hairs, 

 its segments nearly equal. Petals bright yellow, as long or longer 

 than the calyx, broadly cordate. Receptacle hairy. Carpels slightly 

 wrinkled.
