General Biology Additional Information
  • The life-cycle of Palmaria palmata is diplohaplontic and strongly heteromorphic, with a reduced crustose female gametophyte and a macroscopic foliose male gametophyte.
  • Where competition for space and light restricts the occurance of Palmaria palmata on rock the species often has an epiphytic habit on other algae, especially kelps.
