SCHLECHTER'S Tainia Fauriei is the same species as a plant mentioned in 

 our work as Tainia cordifolia HOOK, f ., as it was collected by the same collector 

 at the same place and distributed with the same number. At Kew, I compared 

 my plant with the type of this species, and found it to be identical with the same.
