Electronic Flora of South Australia Genus Fact Sheet
Phylum Chlorophyta – Order Caulerpales – Family Udoteaceae
Thallus uncalcified, more or less complanately branched with numerous laterals, with elongate upper branches bearing alternate, distichous, flabellate branch systems. Lower axes denuded but covered with short, branched, chains of moniliform cells which develop into a thick layer near the base of the thallus. Flabellate systems formed of di-(tri-) chotomous filaments of large elongate "segments" (probably multinucleate), occasionally laterally attached; cross walls formed by ingrowth from the periphery and with a small gap normally remaining. Chloroplasts numerous, discoid, without pyrenoids; amyloplasts present, and also acicular vacuolar crystals.
