The habit of this species is very Uke that of Enteromorpha 

 intestinalis and it grows also in very similar places, as is also 

 pointed out by Collins in »The Green Algae of North America», 

 p. 203. 



It is especially distinguished from E. intestinalis by having 

 the cells arranged in longitudinal rows. 



It occurs in somewhat or quite sheltered places often in 

 brackish and stagnant water, once it was found in great quantity 

 in quite fresh water near the mouth of the Bethlehem river at 

 Fair Plane.

Enteromorpha torta Vickers, Phycologia Barbadensis, tab. VI; non 

 Enteromorpha torta Reinb. 



In the »Phycologia Barbadensis« j\F^ Vickers has figured 

 an Enteromorpha which she refers to Enteromorpha torta Reinb.^). 

 As I have now also found this, it seems to me, very character- 

 istic form in the Danish West Indies, I have arrived at the con- 

 clusion that I cannot agree with APe Vickers in considering 

 the plant in question as belonging to Reinbold's species. Major
