The use of phycoetythrin absorption spectra in the classification of Red Algae

The phycoerythrins of 25 species of the Rhodophyta have been examined; absorption spectra of the native phycoerythrins of these species have been recorded. In taxonomy only a very limited use of phycoerythrin absorption spectra can be made. As a criterion it is only useful at species level and sometimes at genus level.
