This little plant was lirst described by Grateloup, in the 

 year 1 S< >7. under the specific name which I adopl in pre- 

 ference to that proposed by Agardh twenty years subse- 

 quently. By the term ocellatum, Grateloup n«> doubl in- 

 tended' to allude to the eye-like spots caused by the density 

 of the ramuli at the tips of the branches. The branches in- 

 deed, when the plant is displayed on paper, resemble deli- 

 cate feathers, each marked with an eyelet. When growing, 

 Mrs. Griffiths compares them, with equal propriety, to the 

 brushes with which bottles are cleaned.

There are two principal varieties of this pretty sp. 

 one of them found on nu-lvs near low-water mark, the othe i 

 dredged in deeper water, and often on a sandy or shingly 



a. or among Z<>sf< ,-<>. In the first, which is r 

 Bented in our figure, the frond is more robust and bushy, 

 the branches more regularly alternate, and the colour fre- 

 quently very dark. Bui this last character varies accord- 

 ing to minor circumstances of each locality. This variety 

 i> frequently found in fruit, the pods being more commonly 



found than the capsules. In the second variety tie 



are more Blender, the branches much divaricated, and the
