but in his comparison he is confusing the Australian, the New Zealand, 
and the Tasmanian species, and clearly has not appreciated the essential 
differences in the characters afforded by their leaves.

The leaves and the appendages, as Mueller points out, are longer 
and narrower than those of C. novae-zelandiae . With regard to the 
appendages, however, the axis of the fold, instead of being at right 
angles to the petiole as it is in the New Zealand plant, is inclined at an 
angle of 45 0 to the petiole, so that the base of the leaf lobe—one side 
of which is the folded edge of the appendage—is sagittate. The con¬ 
spicuous appendages are lanceolate-obtuse, and some a cm. or more in 
length. According to Mueller the whole leaf with its upturned lobes 
keeps the surface of the leaf away from the icy water in which the 
lower part of the plant is immersed.
