| Summary: | Seriocarpa rhizoides Diehl 1969 was collected in abundance from the calcareous sand of the Josephine Bank (between Portugal and Madeira) during the „Meteor“ seamount cruises in 1967. Attachment in this loose soft substratum is effected by fine anchoring strands of the tests. Two irregular series of small polycarp-like hermaphrodite bodies which are embedded in a connective tissue lie directly below the endostyle, forming a tubular compound gonad, but without common ducts. The intermediate nature of the reproductive system with respect to arrangement and structure increases our knowledge about the polygenetic relations of the stylid-genera. Some of the hitherto known ecological facts point to the presumed „seamounts effect“ on this species. ... |
