Description
Polysiphonia fucoides is a relatively small seaweed. It grows as branched, cylindrical tufts reaching 20 cms or more in length. The branches are themselves densely branched, the main branch usually distinct. It is attached by matted branches which produce rhizoids. The branches are comprosed of a central axes of cells surrounded by 11 to 21 pericentral cells all of the same length. Cortication is generally absent but may be formed on the major branches near the holdfast the cells growing down in grooves between the pericentral cells.[2]
Reproduction
The plants are dioecious. Spermatangial branchlets occur near the apices of the branches. Cystocarps are borne on short stalks. and tetrasporangia occur in series towards the apices of the branches.[2]
