they did not know of its occurring regularly on the open plains north- 

 west of San Bernardino. 



Purshia glandulosa Curran, and Prunus fasciculata Gray, I can 

 find no account in Parish's "Plants of the San Bernardino Mts." 

 or in Abrams' "Trees and Shrubs of Southern California" of either 

 of these shrubs having been found on the south side of the San Ber- 

 nardino Mts., (the Cismontane Area). If I have identified this plant 

 correctly Purshia glandulosa is fairly plentiful at Verdemont, a sta- 

 tion on the Santa Fe, about 8 miles east of San Bernardino and some 

 miles below the lower edge of the mountains. Prunus fasciculata 

 grows near Cajon Station on the Cismontane slope of the mountains 

 about 4 miles below the summit of the Cajon Pass. Abrams does 

 speal^ of this shrub being found in Lone Pine Canyon which is some 

 miles to the west and I think on the desert slope. 



Yucca Mohavensis Sargent. There are 3 or 4 large plants of 

 this species to be found in the Plung Creek wash, two miles south 

 of Highlands, and six miles north of the mouth of San Timoteo Can- 

 yon. The trunks measure about 15 feet long as they lie prostrate 

 near the ground. Prof. Jepson in his "Flora of Cal." speaks of this 

 plant as "extending west to the San Bernardino Valley," but he gives 

 no specimens from the valley. He records one from the San Ti- 

 moteo Canyon, a canyon leading into the valley where there are or 

 were some plants of the species near the lower or cismontane exit. 

 But the plants I have reference to are about 6 miles inside of the 

 San Bernardino Valley.
