morpha rather than a Cladophora, but occasionally the free branches 

 have a series of secund, two or three-celled ramuli, issuing one from each 

 articulation. In the entangled mass more branching of this character 

 will be found, also long normal branches in no definite order. The habit 

 of C. intertexta is much like that of C. repens (J. Ag.) Harv., but the 

 filaments are two or three times as large as in that species, and the color 

 is a light green, somewhat whitish in drying, instead of the dull olive 

 green of C. repens ; the latter has, moreover, a vaguely dichotomous 

 branching, and articulations many times — according to Harvey, even 

 twenty times — the diameter. C. herpestica (Mont.) Kuetz. has fila- 

 ments of about the same size as C. intertexta, but it has long articula- 

 tions, up to fifteen diameters, and irregular branching, with the upper 

 branches fasciculate.
