In the more common appearance of this species, the ramuli are alternate,
merely spreading, and subpinnate.
Sphacellaria cirrhosa is so very variable a plant, that I
have not ventured to propose the Alga represented in the plate
as a distinct species; yet the horizontal and opposite ramuli
seem to indicate a specific difference. The fact also of the ramuli
not being distichous, hut spreading in every direction, also
deserves consideration.
