Bumpy

Bumpy little green huts with umbrella roofs sprout along the hillside.  Another new oddball cactus for me!  This one is a mass of deep green lumps and bumps, each crowned with a halo of spines.  Each of the bumps in this image is about as big as the pad of your thumb, if not a little larger.  I didn't directly compare my thumb, because one of them was holding the camera, and the other was opposed to being pricked.
