The Tasmanian Caltha is a markedly distinct plant from the 
species found in the Victorian Alps, especially as regards the size and 
morphology of the leaves. In C. introloba the appendages are merely 
the infolded elongated basal lobes, but in C. phylloptera the type of 
appendage closely resembles that of C. alata , A. W. Hill, and as in that 
species the appendages are entirely detached from the leaf lobe and 
spring from the lamina itself, forming two erect wings on either side of 
the midrib. The appendages are usually so deeply lobed at the base 
that they come to be divided into two very unequal portions. 
Hooker, in the Flora of Tasmania, points to the similarity between 
the New Zealand and Tasmanian forms, and doubts if they are distinct;
