Section III. Axis calcareous, solid, not jointed, uniformly calcareous to the 

 apex of the branchlets. 



Fam. 13. CORALLINE. 



Axis inarticulate, solid, calcareous, more or less hard and stony. 

 Bark smooth, granular, with irregular-shaped calcareous spicula. 

 Polypiferous cells simple, more or less exserted. 



The chemical character of the axis may be easily discovered by a 

 small quantity of muriatic acid.

 over the surface on all sides of the branches. Axis red. (See Ellis,
