Obs. This fine plant, in habit resembling a Ficaria, appears 

 to be rare It was first found in the Falkland Islands. In the 

 system of De Candolle it is placed in the genus Caltha, and 

 together with C. appendiculata, forms a separate section, 

 under the name of Psycrophila. De Candolle thinks that 

 this section will eventually be constituted a distinct genus.

 sub-duplo longioribus ; stylis staminibusque corolla breviori- 

 bus ; sepalis acutis, foliorum segmentis profunde lobatis.
