P. cespitosa, laxe ramosissima, ramis tortuosis, basi incrassatis 

 superne 1^-3'" crassis, apice scepe palmato-digitatis, ramulis extremis 

 4-6'" longis. Corallum cellis majusculis (prope 5'") stelld viz con- 

 spicud, columella nulld. 



Cespitose, very ramose, lax, branches tortuous, incrassate at base ( J to 

 | of an inch), above | to J of an inch thick, apex often digitato- 

 palmate, summit branchlets 4 to 6 lines long. Corallum with the 

 cells rather large (nearly i a line), star scarcely distinct, columella 

 none.

Grows in large ragged clumps. The small branchlets, correspond- 

 ing to the verrucre in other species, are often irregularly clustered at 

 the extremities of the branches like short slender fingers. The branches 

 are smaller and less crowded, than in the damicornis. The clumps 

 are often a foot in diameter, and six or eight inches high.
