toothed. Flowers bright yellow, larger than the last, on long slender 

 downy axillary and terminal pedicles^ the calyx of eight or ten lanceo- 

 late segments, the outer ones smallest. Petals roundish, heart-shaped, 

 as long or longer than the calyx, four or five. Receptacle small, dry, 

 hairy, bearing a few pale smooth kidney-shaped carpels, slightly rugose. 



Habitat.— Esiiiks, fields, and waste places ; less frequent than the 

 last. 



Perennial ; flowering in June and July. 



This is distinguished from the last species by its petiolated leaves, its 

 entire or sparingly cut stipules, and the flowers are almost as large 

 again. From P. reptans, with which it is sometimes confounded, it is 

 distinguished by its less creeping shorter and not rooting stems, its 

 leaves being solitary, and not several from the joints, as in that species ; 

 its flowers are smaller and terminal, as well as axillary, and its carpels 

 are smooth and slightly rugose, and not rough, as are those of P. 

 reptans.
