Identification Factsheets of the
Marine Benthic Flora (Algae)
of Southern Australia
Author: R.N. Baldock (Bob)
© R.N. Baldock 2010
These factsheets have been developed to aid in the identification of
species from the rich algal diversity of our southern Australian coasts.
Through the personal efforts of Emeritus Professor H.B.S. Womersley and
those of his many students and helpers, some 90,000 algal specimens have
been added to the main collection in the State Herbarium of South Australia.
Added to this are 20,000 prepared microscope slides of algal structures
essential in species identification.
An overview of the algae factsheets is contained in the introduction.
As an Honorary Associate of
The State Herbarium of South Australia, Bob has spent many years photographing
the species and slides to provide this rich visual experience.
