I am not a botanist and I have never heard the term plastid used in
reference to mitochondria. The definition of plastid I know is:
A member of a family of organelles  unique to plants having their own 
small genome and enclosed by a double membrane (chloroplasts, chromoplasts,
leucoplasts, tonoplasts, etc.) 
Taken from Alberts et al Mol Biol of the Cell
