Two Rough-Shell Types of Macadamia nuts. 
A, desirable type, ovoid in shape, moderate thickness of shell, and good size kernel; B, undesirable type, 
elliptical shape, and very thick shell. The rough-shell macadamia is characterized by a knobby surface 
of the shell and a sweeter flavor of the kernel.
