Linanthus parryae Leptosyne bigelovii 



Yuba County 



A single day, March 21st, was spent at Marysville in the 

 Sacramento valley, elevation 66 feet, distance north of San Fran- 

 cisco 142 miles, or over 400 miles north of Bakersfield, and the 

 average rainfall at least twice greater. Of the ten species of 

 flowering plants collected here, four were also obtained in Kern 

 county, two of them, Salix lasiolepis and Plantago erecta^ in the 

 Tehachapi mountains at elevations of 2500 to 3000 feet, and the 

 other two, Lepidium nitidum and Lotus Wrangelianus^ near 

 Bakersfield. But only one of these, Lotus Wrangelianus^ is 

 idantical in form. The collection from this place is too small 

 for trustworthy comparison.

Sutter County 



March 22d was spent at the Marysville Buttes, an isolated 

 group of mountains fifteen miles or more northwest of Marys- 

 ville, rising about 2000 feet above the Sacramento valley, and 

 wholly unconnected with either the Sierra Nevada or the Coast 

 Range. Only one of the ridges was ascended, the summit about 

 1200 feet above sea level. Of the sixteen species collected, four 

 are also listed from Kern county, but only one, Orthocarpus at- 

 tanuatus^ similar in form. The other three are Pterostegia dry- 

 marioideSy Lupinus micranthus^ and Gilia staniinea. The Kern 

 county plants were collected at elevations of from 1000 to 4000 

 feet.
