Not so. The apostrophe has more than one use.
In this case it denotes that something is missing, i.e. the "flower" part
of Cauliflower. Therefore cauli' is correct. Same with 
'bus = Omnibus
taxi' =taximeter cabriolet
and pram' = perambulator.
Is uppose bra' being short for brassiere would be correct too,
and my original example of photo' would also be appropriate.

Many of these longer words have of course long since dropped
from our vocabulary so it just depends how picky you want to be.
