Originally coined by French botanists, from Ancient Greek πρό ‎(pró) and φύλλον ‎(phúllon).


prophyll ‎(plural prophylls)

  1. (botany) The frequently specialised or reduced leaf produced at the first node of a new shoot.

Usage notes[edit]

Between the coining of the word and the second half of the 20th century, a great amount of confusion existed in the definitions of the word and its equivalents in French and German. Many authors believed the prophyll to be a specific structure, and specialists of the Aroidea often give it such a sense.
