Primary segments elongate to pyriform, 400- 
700 ii long and 200-400 /x wide, communicat- 
ing with the axial siphon; secondary segments 
elongate— linear, 450-560 n long and 120- 
200 id wide; tertiary segments clavate, 130-400 
H long and 100-130 /x wide; secondary and

This is the only species of the typically 
tropical-subtropical genus Dasycladus known 
from southern Australia. It is closely related 
to the type species, D. clavaeformis (Roth) 
Agardh from the Mediterranean, Canary Is-

the size of the branch segments and in the 
rounded ends to the tertiary segments (the
