glaucescence

The story

1. New Latin · derived fromglaucēscēns“glaucescent”
2. New Latin · derived from*glaucēscentia
3. English todayglaucescence

By surface analysis, glaucescent + -ence, though Merriam-Webster presumes a New Latin *glaucēscentia, from New Latin glaucēscēns (“glaucescent”). However, the Missouri Botanical Garden's A Grammatical Dictionary of Botanical Latin holds no examples attesting this, instead attesting Latin glaucēdō. By surface analysis, Latin glauc(us) + -escence.
