Dear tsuwm: Very interesting, the root meaning "colorful". Poikilothermal is biological term for
"cold blooded", meaning temperature of environment, actually. "Poikiloc;ytosis" is a term about
cells in blood, which I have now got to go look up.


poikilocytosis n.


the presence of abnormally shaped red cells (poikilocytes) in the blood. Poikilocytosis is particularly
marked in myelofibrosis but can occur to some extent in almost any blood disease.

I don't know, tsuwm. I'm beginning to be skeptical of definition of "poecilonym" = synonym.
