estuaries, &c. Annual. Vegetates at all seasons. Hxcessively 
common. 
Groar. Distr. Generally diffused throughout temperate and tropical latitudes, 
in both hemispheres. 
Descr. foot a small disc. Fronds tufted, or clothing wide spaces of rock, from 
an inch to six or twelve inches long or more, sometimes as fine as hair, 
sometimes half an inch or more in breadth, extremely variable in aspect and 
in ramification. The wider specimens are often but slightly branched, 
having a principal stem furnished with several, irregularly inserted, long 
and simple lateral branches ; the narrower individuals are repeatedly divided ; 
their branches bearing one or more sets of lesser branches; and other va- 
rieties have the branches, or the whole plant, clothed on all sides with 
slender capillary ramuli. All the branches, and their divisions, taper greatly 
toward the base, and the apices are generally blunt. The tube is more or 
less strongly compressed in most cases, but some of the wider varieties are 
inflated, in which case they can only be known from JZ. intestinalis by being 
branched. The colour is a beautifully brilliant green, and the surface glossy 
as silk. The substance is membranous, and adheres but imperfectly to 
paper.
