Ravenel made collections of this alga from the Santee Canal in 1851.  He sent some of his specimens to George Engelmann in St. Louis, who forwarded them to Alexander Braun (1805-1877), a German botanist studying algae.  Braun treated Ravenel's plants as a new species in 1856.

Ravenel lamented in 1876 that "the locality [of the algal collection] is now lost, as the old Santee Canal (cut nearly 100 years ago to connect the Santee and Cooper Rivers) has been abandoned since the opening of the North-Eastern Railroad. It may possibly be found in still water in the vicinity. My specimens were collected in June, when in bloom."
