and Miscellaneous Particulars. 
Greville observes, " This is a most curious tribe of plants, whose structure, I am convinced, is by no means 
well understood. At present, I have only minutely examined the fruit of C. vulgaris. Under a high power of 
the microscope, the globule is found to consist of seven triangular scales, which in maturity separate from each 
other, and produce the dehiscence of the globule. Each of these scales has a vacant portion in its centre, but 
the margin, which has a fluted appearance under a small magnifier, consists of a number of parallel, linear, 
oblong, hyaline, hollow tubes, placed [at small intervals from each other, those forming the angles of the scale 
being branched. Within these tubes are a profusion of orange, globular, minute bodies (exactly similar to 
the sporules of many cryptogamic plants), arranged in no order, and escaping on the least injury to the tubes. 
It IS these little bodies which give the orange color to the globule. Within the globule is a mass of elastic 
white filaments, much convoluted, and distinctly either jointed or transversely rugose." 
The calcareous matter of the stem and branches is not an adventitious incrustation, but is the result of some 
peculiar economy in the plant itself, as it evidently originates from within, and is covered with the cuticle. It 
IS supposed to be analogous to the siliceous deposit beneath the cuticle of Equisetum. 
2296. Ceramium. So called from zis,o!.!^oi, a little measure, in reference to the appearance of the capsules. 
AU the species are found in the sea, and among the substances cast up upon the shore.
