Melocactus Matanzanus is the smallest,which come from Cuba and is very pretty.It makes its cephalium in 4 to 5 years.

Neutral palmbob On Jul 22, 2004, palmbob from Acton, CA (Zone 8b) wrote:

smaller green Cuban species- matures quickly at about 4" in diameter, so if you want a relatively cheap melocactus with a cephalium already, this one could be for you. Once the cephalium forms, the cactus itself won't grow any/much... just the cephalium. Needs protection from hot sun and cold/damp combinations.
