Genus CHLORODESMIS Harvey & Bailey 1851: 373

Phylum Chlorophyta – Order Caulerpales – Family Udoteaceae

Thallus uncalcified, tufted, composed of coarse, free filaments, distantly subdichotomous, arising from a dense, entangled, rhizoidal base. Filaments constricted above each dichotomy, constrictions symmetrical or asymmetrical.

Reproduction: Reproduction (known in C. baculifera) by zooids formed in ovoid zooidangia in dense lateral clusters on upper branches (Ducker 1965).

Type species: C. comosa Harvey & Bailey.

Taxonomic notes: Chlorodesmis is a genus of some 6 species (Ducker 1967) in the Indo-Pacific region. It differs from most other genera (except Pseudochlorodesmis) of the Udoteaceae in that the filaments are free, not entangled or united to form a complanate or slightly compressed thallus.
