Castanea chrysolepis, Hook.— A shrub 4° high. On Olanche Mount- 

 ain, at from 8-10,000 feet altitude (344). 



LORANTHACE^. 



By Dr. George Engelmann. 



Arceuthobium occidektale, Engelm., in Brewer & Watson's Fl. Cal. 

 vol. 2, ined. — On Finns 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 Pifios, 

 on a form of Pinus ponderosa. 



SAURURE^. 



Anemopsis Californica, Hook. — Santa Barbara (3). 



CONIFERiE. 



By Dr. George Engelmann. 



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



Pinus Balfouriana, 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. 

 flexilis, and still more to the Cembroides, but the small, large-winged seeds 

 distinguish it from them. The smoothness of the leaf-edges is a feature 

 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. 



Juniperus Californica, Carr. — A large shrub or small tree with thick 

 branchlets; leaves mostly in threes, with minutely fringed edges; berries 

 mostly oval, 5-6" long, glaucous-reddish, dry and sweetish, with one or 

 sometimes two large seeds; cotyledons about 5. — Conif. 58; Engelm. Junip. 

 588. Kern River, at 9,800 feet altitude, Rothrock (337), 1875. The 

 specimen is a small leaf-branch only, without fruit, so that the name may be
