multis obsoletis ; stelld conspicud, duabus lamettis infra fere conni- 

 ventibus. 



Stout foliate, fronds deeply digitate lobed ; lobes narrow, oblong, or 

 ligulate, often 2 feet long, 2 to 4 inches wide, and J to l inches 

 thick. Corallum below, with short crowded calicles; above, calicles 

 tubiform, unequal, 2 to 2 lines long, and | of a line broad, erect, 

 never nariform, many obsolete; star distinct, two lamellae nearly 

 uniting below.

The long narrow lobes of this spreading digitate species, at once 

 distinguish it from the palmata. The calicles are less stout and none 

 are nariform, although many are obsolescent, and others are reduced 

 to immersed cells. They are also more distinctly stellate. The lobes 

 are often convex below, and concave above, and at the extremity are 

 about half an inch thick.

Spreading foliate, fronds rather stout, convoluted at base, the margin 

 consisting of incipient branchlets scarcely \ of an inch thick. Co- 

 rallum below, with short crowded calicles ; above, calicles slender 

 tubiform, often 1 lines long and to of a line broad, never nari- 

 form, sometimes acervate in lines, many immersed cells; star scarcely 

 distinguishable.
