Subjective junior synonym of Encope.
Remarks A clear separation between the Encope (Echinodesma) and Encope (Encope) is difficult because all intermediate states between a continuos and fully disjunct interambulacrum 5 exist. Separation of the disjunct forms seems thus arbitrary and Echinadesma is considered as junior synonym of Encope here.
