mountains of Santa Cruz, a coast range running- due north across 

 the l)ay from Monterey, and distant by water aljout 25 miles, 

 although GO miles by land ; afterwards he found it in the Sacra- 

 mento country, growing upon the ridge generally termed by 

 emigrants from the United States, the Californian Mountains. 

 Mr. Ilartweg says, " after crossing the Chuba River you pass 

 the prairie, and enter the mountains near Bear Creek, where 

 you have to pass through an interminable wood of Pinus Sabini- 

 ana ; and in ascending the gradual acclivity of the mountain you 

 lose the region of Pinus Sabiniana and enter that of Pinus 

 Benthamiana, which seems to be characteristic of the upper 

 region." Some trees of this noble Pine attain an enormous 

 size ; the largest which Mr. Hartweg measured in this locality 

 was 28 feet in circumference and 220 feet in heiglit. It gene- 

 rally grows in masses or intermixed with a few solitary Pinus 

 Lambertiana, which is of equal dimensions in these regions. The 

 lofty mountains surrounding Bear Valley are also well wooded 

 by Pinus Benthamiana. 



It was named by Mr. Ilartweg in compliment to George 

 Bentham, Esq., late Secretary to tiie Society. There is little 

 doubt but it will prove quite hardy, and a very valuable timber 

 in England.
