Characteristics : This is the classic coastal lagoon rush that forms large dense bush clusters with prickly leaves and stems. Differs from Juncus maritimus by its compact inflorescence and capsular fruits, the latter clearly much larger than its sepals. (Be careful with subsp. tommasinii, it has small capsules!) Additionally, Juncus maritimus is rhizotomous, usually growing in lawns and its inflorescence is very lax.
