Lamouroux: separates them into Cryrra where the stems are 
scandent(2): 
And Laomerpea where they are not; the bells also are smaller and 
the branches shorter(3). 
SERTULARIA, Lin. 
The Sertulariz have a corneous stem, sometimes simple, some- 
times ramous, on the sides of which are cells, extremely various in 
form, that are occupied by the Polypi, all connected with a gelati- 
nous stem that traverses the axis, like the medulla of a tree. 
They propagate by ova or buds, which are developed in cells larger 
than the rest, and of a different form. 
The various directions of their cells have caused them to be sub- 
divided.
