262 THE MARINE BOTANIST. 



water. Rare. Plymouth, Rev. W. S. Hore. Sal- 

 combe, Devon, Mrs. Wyatt. " Involucres of tetra- 

 spores whorled round the dissepiments of the 

 branches. This is an exceedingly slender plant, 

 densely tufted, and of a fine rosy red colour. The 

 small size of the filaments distinguish it from G. 

 corallina, and the difi*erent arrangement of the fruit 

 from G. barbata and G. setacea." 



G, secundijiora, ^^ On rocks at extreme low- 

 water-mark. Very rare. Discovered at Bovisand 

 near Plymouth, by the Rev. W. S. Hore, 1846. 

 Filaments tufted, four to eight inches in height, 

 thicker than hog's bristles, not sensibly attenuated 

 upwards. From G. setacea this plant may at once 

 be known by its large size, its comparatively shorter 

 joints and more lubricous substance, but especially 

 by the very obtuse, cylindrical upper ramuli, which 

 do not taper to a point, but are of a very equal 

 diameter throughout. From G. corallina, which in 

 many respects it resembles, its cylindrical articula- 

 tions and difierent inflorescence distinguish it." —
