A plant that reproduces through chalazogamy, where the pollen tube enters the ovule through the chalaza instead of the normal micropyle opening.
From Greek 'chalaza' (hail, granule) + 'gamos' (marriage, reproduction). Coined in the 20th century to describe an unusual reproductive pathway in plants.
Some plants have evolved to take a 'back door' into reproduction—pollen bypasses the normal entrance and sneaks through the chalaza, showing how evolution rewires even basic biological processes!
