Trophosome . — Colony consisting of a main stem, which gives off plumose branches near its base. 
Branches consisting of a slender shaft, giving off alternate rather distant hydroeladia, which are forked 
and divided into rather distinct internodes which are long and slender and separated by straight nodes. 
Hydrothecse small , cup-shaped, almost entirely adnate behind. A pair of trumpet-shaped nematophores 
are inserted just above the aperture of the hydrotheca, another single one below its base, and others 
scattered rather irregularly along the hydroeladia and stem.
