Cal. none. Pet. 5 or more, inferior, ovate, or elliptical, 

 nearly flat, spreading. Necf. none. Filam. numerous, 

 rather swelling upwards, shorter than the corolla. Anth. 

 terminal, erect, oblong, of 2 lobes, bursting at the outer 

 edges. Germ, superior, 5 to 10, erect, oblong, com- 

 pressed. Styles none. Stigmas obtuse. Caps, [follicles,) 

 as many as the germens, cylindrical, pointed, two-edged, 

 erect or spreading, bursting at the upper edge. Seeds 

 numerous, from the margins of the capsule, oval, with a 

 small rounded prominence at the extremity. 



Perennial smooth herbs, slightly acrid, natives of watery si- 

 tuations, with simple leaves, and yellow^owers. Those 

 of the southern hemisphere have, as M. DeCandolle re- 

 marks, permanent petals, or, as he considers it, a per- 

 manent calyx : in those of northern climates the same 

 part is deciduous. Two species, C. asarifolia and lepto- 

 petala, have numerous narrow petals, differing from the 

 rest as Jlanunculus Ficaria does from other species of 

 Ranunculus; but M. DeCandolle is too judicious to se- 

 parate them, on that account, from the rest.
