Caulerpa elongata f. distich a Taylor 1950: 55, 
pi. 52, fig. 1; Dawson 1956: 37 (as C. 
elongata) 
D. 13723. Caulerpa elongata is supposed to 
be distinguished from similar forms of C. 
webbiana by its more lax and erect habit and 
absence of the abundant ramified filaments 
from the stolons. However, this specific dis- 
tinction needs study. Taylor’s plant is prob- 
ably the same as that treated as C. webbiana 
f. elegans by Yamada and Tanaka 1938: 62, 
fig. 4.
