Enteromorpha salina Kiitzing, v. polyclados Kiitzing 



Plants entangled, contorted, slender, vaguely branched, throughout 

 or sometimes only in the lower portions beset with short tapering patent 

 branchlets; main branches with squarish cells about 16 /x wide, generally 

 shorter than broad, in definite rows; branchlets uniseriate toward the tips. 



Kiitzing 1856, p. 13, pi. 36, fig. II (as E. polyclados) ; Farlow 1902, 

 p. 89 (as E. clathrata) ; Collins 1909, p. 202; Setchell & Gardner 1920, 

 p. 257. 



This material, reported as E. clathrata by Farlow, consists of a smaller 

 and more entangled plant which agrees tolerably well with E. salina v. 

 polyclados. The variety has been accepted as an element in the Californian 

 flora by Setchell and Gardner, and for the Gulf states by Collins, though 

 first described from Europe. It is a plant of shallow, quiet water.
