root and branch, has a pale, horny, hyaline aspect. ‘‘ The 
stem is divided at regular intervals, as in the other species ; 
but instead of several rings or twists above the origin of 
the cells, there is a small internodal jomt; and the stalk of 
the cell, instead of being ringed, consists of two or three 
unequal joints, much as they are formed in the genus 
Halecium. The cell itself is of the normal thin hyaline 
texture, and bell-shaped, but the rim is sinuated on the 
proximate margin, so that the aperture resembles very much 
the mouth of a jug.” (Dr. Johnston.) 
As jugs differ in form, we may mention that it is a jug 
of the common form, the rim of which is depressed towards 
the handle, giving the mouth a scooped appearance.
