It seems this plant may be the silver or white form of Hechtia montana. Most of the photo's that I can find on the net are of a green or some what green looking plant.
It also seems that a silver or white Hechtia's are common.
To name a few Hechtia's that are silver or white are:
Hechtia aquamarinaHechtia argentea
I looked at FCBS (http://fcbs.org/) Photo Index and some photo's I couldn't tell what color the plant was. But the plants listed below might be silver or white.
Hechtia montana was slow to root but once rooted is growing what I would call fast.
