On most of the stem the coenenchyma is rulil)ed off. In the upper third of the colony, ho\ve\ er, whiTc it is ])artly preserved, there is a .single zooid jilaced on tlie stem itself ojiposite a branch. The basal part of the stem is about 1 mm iu diameter. The coenenchyma is fairly thin and the round axis measures here about mm in diameter. The diameter of the stem in the top of the colony is about nun, and the diameter of the internodes of first order may be about mm: it is, however, usuallv only mm and sometimes even less.
