Robert P. Munafo, 2000 Mar 2.
Colloquial name used by Milnor among others to describe the Julia set of R2.C(0). Also, by extension, used to describe the same shape as it appears in Julia sets of other cardioid cusps like R2F(1/2B1)S.C(0).
This is the shape of Type CC embedded Julia sets, which are distinct from all other embedded Julia sets because of their simple open interior with its very clear binary branching structure of nodes and connecting filaments.
