Origin of zoarium¹

First recorded in 1880–85; zo- ( def ) + -arium ( def )

The zoarium is of delicate appearance and branches sparingly.

The zoœcia are not distinct from one another, but in dendritic forms the zoarium is divided irregularly by chitinous partitions.

A zoarium with its included polypides is finally produced from the young polypide by the rapid development of buds.

The zoarium as a whole is either recumbent and adherent or at least partly vertical.

The growth of the zoarium is much more luxuriant, and the form of the resting buds is different.
