Rose in " North American Flora " (1905) unites the two species 
under the older name. Soon after, S. Liehmannianum 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
