Chalazogamy Chal`a*zog"a*my, n. [Chalaza + -gamy, as in polygamy.] (Bot.) A process of fecundation in which the pollen tube penetrates to the embryosac through the tissue of the chalaza, instead of entering through the micropyle. It was originally discovered by Treub in {Casuarina}, and has since been found to occur regularly in the families {Betulace[ae]} and {Juglandace[ae]}. Partial chalazogamy is found in {Ulmus}, the tube here penetrating the nucleus midway between the chalaza and micropyle. -- {Chal`a*zo*gam"ic}, a. [Webster 1913 Suppl.]
