I used to be a botanist and I have seen the term plastid to refer to
mitochondria in several older cytology text books. That usage was
definitely frowned upon in my old department, BTW. (Heck, they
wouldn't even formally consider photosynthetic plastids as
"chloroplasts" unless they contained cholorphylls a and b.)
