The specimens from Nantucket differ somewhat from the ordinary 

 form. They consist of rather dense tufts of stout stems, two or three, 

 inches high, and rather sparingly branched. The cells are larger than 

 usual, elongated obovate, five or six times as long as broad ; those of 

 the same pair are not exactly opposite. Aperture deeply crescent- 

 shaped, facing a little outward. Many of the cells, toward the base of 

 the stems, give rise to one or more curious processes from near the base 

 of the cell ; these are, at first, slender tubes, rising from a thin roundish 

 spot on the cell, but soon they divide at the tip into two, three, or 

 four forks, which are at first regularly recurved ; later these become 

 much elongated, and are converted into slender rootlets or stolons.
