CORNACEAE 



Note on the fruit. — "The drupe is purple-black when ripe, like a black tartarian cherry, and 

 quite as juicy, shining and smooth. The pulp gives a strong purple stain. The sweetish taste 

 would be pleasant but for an intense bitter accompanying it. It ripens in the middle of August" 

 (J. P. Tracy, Three Creeks, n. Humboldt Co., 1921, in Jepson Corr. 15:312. ms.).

Geog. note. — In Southern California and in the South Coast Ranges the known localities for 

 Cornus nuttallii are few, scattered and restricted in area. One station is dubious: After more 

 than eighty years there has been no validation of the record "Monterey" in the Botany of the 

 Mexican Boundary. In the North Coast Ranges, on the contrary, the Mountain Dogwood is often 

 a marked constituent of the forest in the Mendocino and Humboldt woods. It is also frequent in 

 portions of the Sierra Nevada.
