History : The description of this species occurred on 29th of August 1885 by N.E. Brown and was based on herbarium material that was collected by G.S. Jenman at the Kaieteur Falls at the Potaro River in British Guyana.

Comments : The difference between this taxon and Phrag. lindleyanum are so small that according to Gruss (1995) it's not very useful the keep the status of species. But since there are some differences declaring it a synonym of Phrag. lindleyanum as Stein did, isn’t very useful either. It's best to give it the rank of variety, as was already done or suggested by Cogniaux, Reichenbach f., Pfitzer and Cash.
