Sea Spleenwort Likes the Rain

Sea Spleenwort, Asplenium marinum
Sea Spleenwort, Asplenium marinum, is a common fern found in rock crevices through out the coasts of Ireland (1). As such, it is exposed to highly saline conditions which can delay spore germination and even prevent it completely at high concentrations (2). However, once a decrease in salt concentrations occurs, due in vivo to rainfall, spores regained their germination ability.
