Those, in which the interior is filled with corneous threads, still present some analogy to the Ceratophyta. In the CoRALLINA, Lin. We observe articulated stems placed on species of roots, and divided 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. officinaz.is, 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 arranged 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(!). Lamouroux also distinguishes, but for trivial reasons, AMPJUROEA, Where the articulations are elongated(2).
