- A gametophyte development stage during which a gametophyte undergoes filamentous growth and that succeeds spore germination and precedes a thalloid development stage (planar growth) or gametophore development stage. [source: POC:Ramona_Walls]
- Comment
- The protonema phase ends with the development of gametophores in mosses, some other bryophytes, and leptosporangiate ferns and with the development of a thallus in other bryophytes, although protonema tissue may persist of continue to develop after this.
