 Spruce. — The present and not a few of the following species of authors are very 

 puzzling to me. The one now under consideration appears to have an extensive 

 range in South America, from the Atlantic to the Pacific Ocean. It was first 

 described from a Chilian specimen of Chamisso.* 



* Closely allied to P. spectabile, in general habit, form, and ramification, is the 

 following Nephrodiaceous plant, my specimens of which, in consequence of my over- 

 looking the involucres, I had placed in my herbarium with Phei/opleris. It should 

 have been inserted at p. 125 of this volume, next after sp. 125 (.V. villosiim).
