up prairie. A ride of fifteen miles brought me to the foot of the 

 mountains. The lower range, as in the former visit higher up 

 in the valley, is occupied by Ceanothus No. 285, a few live Oaks, 

 and Pinus Sabiniana. Following a small rivulet, I found there 

 Mentha No. 348, Labiata No. 352, Stenactis no 353, a shrubby 

 Labiata, no, 355, with large white flowers, and Collinsia tinc- 

 toria, No. 354. This new species of Collinsia is of stronger 

 growth, though less striking, than C. bicolor; it grows chiefly 

 in the dry sandy bed or on the banks of the rivulet, and pro- 

 duces its yellowish flowers mottled with purple much later than 

 C. bicolor. On a subsequent occasion, when I returned to this 

 place, to procure seeds or it, my hands were stained yellow by 

 the glandular hairs which cover the seedpods, from which cir- 

 cumstance I named ii Collinsia tinctoria. 



"Another interesting plant I found on this excursion is 

 Nemophila speciosa willi white petals, one-third of which is 

 tipped with purple. It grows generally near rivulets, or in 

 damp and partly shaded places. If the few seeds I procured 

 should vegetate, it will prove a gieat acquisition to that hand- 

 some genus. 



"The higher part of this range of mountains is less access- 

 ible than on the former visit. My endeavors to proceed farther 

 were eventually frustrated by the steep banks and swollen state 

 of the Chuba. 



"By the beginning of June I set out again, in company 

 with Mr. Cordna and an Indian, tovisit if possible the snowy 

 heights of the mountains, generally termed by emigrants from 

 the United States the Californian mountains. After crossing 

 the Chuba river we struck across the prairie, and entered the 

 mountains near Bear Creek, where we encamped towards even- 

 ing in a grove of Pinus Sabiniana and Oaks. The vegetation 

 here differed in nothing from that observed on the rio;ht bank 

 of the Chuba on a former visit. Calochortus No. 306, which
