Noun

gemmulation ‎(countable and uncountable, plural gemmulations)

1. (biology) The production of gemmules; reproduction via gemmules

   1978, Patricia R. Bergquist, Sponges

   The actual formation of gemmule's by fresh-water sponges is so clearly an adaptation to seasonal climatic changes, that at first it was reasonable to believe that seasonal alternation itself induced the gemmulation.
