Polysiphonia hendryi var. gardneri
These specimens of P. paniculata were found growing on bedrock in the mid-intertidal of a semi-exposed shoreline on Calvert Island. These are specimen collection numbers SCL 15294 in the UBC Herbarium Algae Databse. Search the collection number in the database for more information on this specimen, or search the species for further occurrences. Image courtesy of Sandra Lindstrom.
Polysiphonia species are finely-branched red algae reaching 25 cm long; P. hendryi var. gardneri is one of the smaller species, at 3-4 cm tall. Branches are thin (measuring less than 2 mm in diameter) and cylindrical. Branching is radial; when branches are spread out in water Polysiphonia species have a fluffy appearance. Polysiphonia
species are differentiated from other finely-branched red seaweeds by a unique bundling arrangement of cell filaments; a microscope is required for accurate identification at the genus as well as species level.
The range of P. hendryi var. gardneri extends from the Alaska Peninsula to Baja California, Mexico.
