The leaf margins are entire and the appendages small. They are 
formed by the indexed bases of the lobes of the lamina, the axis of the 
fold being, as in C. sagittata , Cav., at right angles to the petiole. The 
five perianth-segments are linear-subulate, tapering from the base to 
almost caudate points, and are yellow in colour.

1,525-2,130 m., Hector in herb. Kew. 
A very distinct species, with its deeply crenately-lobed leaves and 
appendages. The appendages are formed by the folding upwards of 
the lobes of the lamina, and are nearly as long and as broad as that 
organ. The five perianth-segments are white, oblong-obtuse or sub¬ 
acute, and broadest above the middle.
