ARCTOSTAPHYLOS. 



ARCTOSTAPHYLOS, Adans. 



Notes on the United States Pacific Coast Species, from re- 

 cent Observation of Living Plants, including a 

 New Species from Lower California. 



BY C. C. PARRY. 

 Presented before the Davenport Academy of Sciences, November .50th, 18S3. 



Of the twenty-five species of Arctastaphylos recognized by the latest 

 authorities (probably to be reduced to twenty or less), fully one-half 

 are comprised within the limits of the United States fiora on the Pacific 

 coast. 



Since the publication of the Botany of California, which assigns 

 twelve species to that district, one Mexican species, viz., A. polifolia, 

 H. B. K., must be withdrawn, and another, A. arguta, Zucc, substi- 

 tuted in its place. Besides this, a wtry well-marked species recently 

 collected near the boundary line in Lower California may properly be 

 added to the list, and is described herewith under the name of A. oppo- 

 sitifolia. A geographically tabulated list of our Pacific coast species 

 will accordingly stand as follows, viz. : 



I. ARCTOSTAPHYLOS, UvA-URSi, L. \ High northern in both hemi- 

 spheres. 

 A. Nevadensis, Gray, j 



A. pumila, Nutt. 



A. Hookeri, Don. )■ Exclusively Californian. 



A. Andersoni, Gray. | 



A. numularia, Gray. J 



A. TOMENTOSA, Dougl. 

 A. PUNGENS, H. B. K. 



A. GLAUCA, Lindl. 



A. BICOLOR, Gray. )■ Extending into Mexico. 



A. Clevelandi, Gray. 



A. ARGUTA, Zucc. 



A. OPPOSITIFOLIA, Parry. 



In this list I have ventured to characterize as doubtful or imperfectly 

 known such as are italicized.
