Oenothera 244, Malvaceae No. 246, produced a splendid effect. 

 A small patch of the beautiful little Leptosiphon aureus, with 

 golden flowers, I also found in the open prairie; it is however, 

 by no means common. 



"The prairies of the Sacramento valley are divided by small 

 rivers, termed "creeks" by tho American settlers: these creeks 

 generally have a border of oaks upon their banks, which also 

 extend over the rich bottom lands. In the dry beds of these 

 rivers I observed plants which nowhere are to be found upon the 

 prairie, the seeds of which have evidently been carried down 

 from the mountains during the rains, as for example, Pentste- 

 mon azureum. No. 255, P. No. 213, Umbellifera No. 257, with 

 an aromatic tap-root, held in repute among the Indians, for its 

 medicinal properties; in rather damp places, Clintonia elegans, 

 C. pulchella (1), and Limnanthes alba. No. 315. 



"A four days slow drive with the waggons brought us to 

 the farm of my companion: the vegetation here differed in no 

 respect from that already observed in the valley. 



"An opportunity of visiting the mountains was afforded me 

 a few days after my arrival, which I embraced with pleasure, as 

 from the hostile character of the mountain Indians towards the 

 settlers, it was not deemed prudent for me to make an excursion 

 in that direction, attended by a guide only; I therefore joined 

 a party of settlers who were going to the mountains to examine 

 the timber, and if possible to find a site for a sawmill. 



"On the first evening we encamped under a large oak, near 

 Pine creek, a little mountain rivulet; here I found Asagraea No. 

 273, Lychnis No. 286, Umbellifera No. 302, Triteleia No. 301,
