Excerpt from American Hydroids, Vol. 3: The Campanularid and the Bonneviellid, With Twenty-Seven Plates If we imagine minute crystalline chalices, crenated or plain round the margin and mounted on slender pedi'cels, twisted spirally or delicately ringed, which are all united and bound to the body on which they grow by the finest network of tubes, we have the form which the polypary assumes in one section of this exquisite group. In another the species are arborescent and sometimes of considerable size, their tree-like tufts presenting the most lovely shapes.
