Abstract
THE Charophyta have usually been regarded as a somewhat isolated group of Thallophyta, but the author of this monograph probably rightly regards them as a family of the Chlorophyceæ. Like some members of the Rhodophyceæ and Siphonales, they have left as records of their existence in past ages the calcareous clothing with which they invested their thallus. With the exception of the oospore membrane all the original plant substance has disappeared.
