CORALLIFERI. ; 44] 
white, reddish, or greenish. It was formerly employed in phar- 
macy on account of its calcareous nature *. 
Lamouroux also distinguishes, but for trivial reasons, 
AMPHIROEA, 
Where the articulations are elongated t. 
JANIA, 
Where the branches are merely more slender and the articulations 
less cretaceous t. 
CyMopoLia, 
Where the articulations are separated from each other§ by corneous 
intervals ; the pores on their surface are more decidedly marked. 
M. de Lamarck had already separated 
Penicriya, Lam.—Neseta, Lamour, 
Where the stem is simple and composed internally of corneous fibres 
woven, and as it were, felted together; it is encrusted by a calcareous 
covering, and terminated by a bundle af articulated branches analo- 
gous to ‘those of the ordinar y Corallinze ||. 
Hatymepes, Lamour, 
Where the stems are articulated and divided as in Corallina; but the 
substance of their joints, which are very wide, is penetrated inter- 
nally by corneous threads, from which the calcareous crust is easily 
detached by acids 4. 
FLapevuaria, Lam., 
Where there are no distinct articulations; they consist of large 
foliaceous expansions formed like the joints of the Halymedes and the 
stem of the Penicillz, of corneous threads enveloped with a calca- 
reous crust **,
