Additional InformationManuel (1988) describes two distinctive varieties. Var. dianthus is large with a tall column when expanded. The disc is deeply waved or folded. The many tentacles give a 'fluffy' appearance. Individuals may be 30 cm in height, with a basal diamer and tentacle span of 15 cm or more. Var. pallidus is a small form not exceeding 2.5 cm across the base with a flat disc without folds. Bucklin (1985) investigated biochemical genetic variation and concluded the presence of two morphs of Metridium senile but that they were variants resulting from different environmental conditions and were not taxonomically distinct and therefore not 'varieties' as described in many texts.
