them as plants; others, however, consider them as having 
very small cells, and as being inhabited by coralliferous Poly- 
pi. In this case they belong to the present order. -Those, in 
which the interior is filled with corneous threads, still pre- 
sent some analogy to the Ceratophyta. In the

We observe articulated stems placed on species of roots, and di- 
vided into branches, also articulated, on the surface of which no 
pores can be seen, and in which no Polypi have hitherto been dis- 
covered.

They are divided as follows. 
CoRALLINA, proper, 
Where the calcareous joints have a homogeneous’ appearance, and 
are without any apparent bark. 
C. officinalis, L.; Ell., Corall., XXIV, a, A, b, B. The bottom 
of the sea on certain coasts is completely covered with this 
coral, the joints of which are oboval and the ramusculi ar- 
ranged like pinnate leaves, bearing other branches similarly 
disposed. It is white, reddish, or greenish. It was formerly 
employed in pharmacy on account of its calcareous nature(1). 
Lamouroux also distinguishes, but for trivial reasons, 
AMPHIROEA, 
Where the articulations are elongated(2).
