Polycystidea

== Translingual == === Etymology === New Latin, see poly-, and Cystidea. === Proper noun === Polycystidea (obsolete, zoology) A division of Gregarinia including those that have two or more internal divisions of the body. (obsolete, zoology) A species of large brown algae, Cystophora polycystidea found in Spencer Gulf, South Australia. ==== Usage notes ==== Taxonomic revisions and the adoption of standardized suffixes for naming biological entities appear to have rendered the name of this "division" obsolete. The intended organism appears to be a parasitic amoeba-like protozoan in the subclass Telosporea rather than the flatworm family Polycystidae. === References === “Polycystidea”, in Webster’s Revised Unabridged Dictionary, Springfield, Mass.: G. & C.
