Puate CCI. 
CORALLINA SQUAMATA, Part. 
Gen. Cuar. Frond filiform, articulated, branched (mostly pinnate), coated 
with a calcareous deposit. Mructification; turbinate or obovate, 
mostly terminal ceramidia, pierced at the apex by a minute pore, and 
containing a tuft of erect, pyriform, or club-shaped, transversely 
parted ¢etraspores. CORALLINA ( ),—from Coralium, coral, 
which these plants resemble in their stony nature. 
CoRaLLIna squamata; decompound-pinnate ; lower articulations cylindri- 
cal, scarcely longer than their breadth ; upper obconical or obcordate, 
compressed, two-edged, their upper angles sharp and prominent ; 
ultimate ramuli very slender, acute.

Descr. Root, a widely spreading, calcareous crust. Fronds densely tufted, form- 
ing frequently large patches some yards in breadth, four to six inches high, 
twice as thick as hog’s bristle, with an undivided or once or twice forked 
stem, set with distichous erecto-patent, more or less decompoundly pin- 
nate branches. These branches are very irregular in length and in their 
degree of composition, some specimens being comparatively bare, others 
closely and many times pinnate. The penultimate branches or plumules, 
are from half an inch to an inch long, with a lanceolate or obovate out- 
line, closely pectinato-pinnate, the pinnules opposite, a pair rising from 
every joint, subulate, and either simple or minutely pinnulate. The 
ultimate ramuli at the apices of the branches are di-trichotomous, a 
circumstance which, no doubt, accounts for the irregularity of ramification. 
Articulations of the lower part of the stem, very short, rounded, bead-like, 
with obtuse angles; the upper ones gradually becoming longer, broader, 
and flatter, with more and more prominent upper angles, until towards the 
summit of the stem, as well as in the lesser branches, all the articulations 
are broadly obconic, compressed, with very salient and acute upper angles. 
Articulations of the subulate ramuli not half the diameter of the others, 
more cylindrical, and thrice as long as their breadth, the terminal one acute. 
Conceptacles (probably of three kinds, two of which only are known to me); 
1, urn-shaped, formed out of the last articulation of a branch, or ramulus, 
simple, or crowned at its superior angles with pair of horn-like ramuli, or
