bacco-pipcs by the Brazilians under the name of Tacuari, and was 

 then the only Brazilian species known, I presumed it to be the if. 

 JiduUfera of Martius, with whose very short diagnosis it agreed pretty 

 fairly, I now find, however, that the following is much more likely to 

 be his plant, as it agrees still better with that diagnosis, and I have 

 seen it moreover in Pohrs collection, made in a great measure in the 

 district whence Martius procured his plant.
