Rose in " North American Flora " (1905) unites the two species 

 under the older name. Soon after, S. Liebmannianum was redis- 

 covered in Mexico by C. A. Purpus and grown at Washington, where 

 Rose was about to describe it as a new species when its identity 

 with Hemsley's plant was recognized. He redescribed it in 191 1
