A frond with young branch from the middle.
Bl - Blade, St - stipe

Size: Whole frond upto 4 cms

The frond consists of a more or less cylindrical stipe gradually expanding above into a flabellate blade. One or two lobes appear on the blade centrally above the stipe region and these expand parallel to the primary blade and overlap it. The stipe as well as the blade do not differ in texture and the blade does not show any distinct concentric dark and light rings. The basal part of the stipe ends in a mass of entangled fibrous rhizoids. The whole thallus is covered by a very thin layer of calcium carbonate.
The thallus is wholly made up of many intertwined dichotomously branched siphons which are constricted at the region of branching, a typical feature of Udotea. Thallus widely fan shaped, heavily calcified. The siphons are laxly arranged at the blade region. The dichotomies of the siphons and the axis run more or less parallel to one another with slight enlargement and undulations. However, in the stipe region the filaments are more closely interwoven and also have short lateral appendages, thus resulting in a mat-like structure. Blade siphons lacking lateral appendages, tightly compact, constrictions above dichotomies symmetrical; stipe appendages repeatedly branched, apices stubby, digitate, blunt.
