Field note. — This Lotus has an area of distribution which is on the whole quite distinct from 

 that of L. stipularis Greene to which, as a variety, it has been referred. It differs, it is said, so 

 much in habit from that species that good field observers in the North Coast Eanges, such as 

 Jos. P. Tracy and M. S. Baker, believe that it should be separated from L. stipularis, either 

 specifically, or referred to some other species. Our first collection (no. 1944) was made on Eed- 

 wood Creek in northern Humboldt Co. in 1902; since that time the specimens have lain in the 

 herbarium under the manuscript name L. aboriginus Jepson. The species name refers to the 

 Indian rancheria on which the plants were collected. The species itself had a few years pre- 

 viously been recognized as a distinct unit by Alice Eastwood, but her name is preoccupied in 

 Lotus.
