Etymology: < meso- comb. form + -genous comb. form. N.E.D. (1906) gives only the pronunciation (mesǫ·dʒĭnəs) /mɛˈsɒdʒɪnəs/.

†1. Mycology. Of fungal spores: increasing by growth from the middle. Obsolete. rare.Apparently only attested in dictionaries or glossaries.

1965 D. D. Pant in Senckenbergiana Biologica 46 164 Three main types of stomatal development were observed. These are the 1. mesogenous, 2. mesoperigenous and 3. perigenous types.

1971 Ann. Bot. 35 1211 In the species of the Annonaceae investigated, the stomata are typically mesogenous.

1985 Acta Bot. Indica 13 178 The meristemoid divides into two unequal cells of which the larger one..enlarges and becomes the mesogenous subsidiary cell.

1992 M. Ingrouille Diversity & Evol. Land Plants 235 In some cases the subsidiary cells arise from the same meristematic cell as the guard cells (mesogenous).
