 vol. 2, ined.— On Pinus Sabiana in "Walker's Basin, Rothrock (429), in 1875. 

 Dr. Rothrock gives quite a graphic account of the shower of seeds expelled 

 from the berries to the distance of ten feet, when on November 12th he 

 shook a limb on which the parasite grew. Also collected on Mount Phios, 

 on a form of Pinus ponderosa.

Pinus monophyllos, Torr. & Fremont— Common at middle altitudes. 



Pinus Balfoueiana, Murr., var.— Was found on Mount Whitney (404). 

 By its leaves in fives, with loose, deciduous sheaths, entire margins, and 

 peripheral (generally 2 dorsal) ducts, this species is closely allied to P.

 peculiar to a geographical group of Pines, otherwise pretty distinct ; we 

 find it always accompanied by deciduous sheaths, but many other species 

 with deciduous sheaths have serrulate leaves. 



Pinus Sabiniana, Dougl. — Walker's Basin, at 3,300 feet altitude. 



Junipeeus Califoenica, Carr. — A large shrub or small tree with thick
