Differentiation of corallite morphology and ability and rate of gemmation observed in colonies of Veraephyllum sytovae, Evenkiella cincta and Minussiella beljakovi have been regarded as a manifestation of polymorphism. Three corallite morphes in a colony have been distinguished: protocorallite, mature corallites and immature, underdeveloped corallites.

Key words: Coral colony, astogeny, polymorphism, Rugosa, Paleozoic.
