BIDENS FRONDOSA LINN. 
On Aug. 17th, 1916, in company with Charles F. Richter, I 
found in the Los Angeles Riverbed, near the North Broadway bridge, 
a plant which I labeled "Bidens sp." and laid away for future study. 
It was nearly forgotten until recently Dr. A. Davidson found the 
same plant on Alvarado Street and gave me a specimen. Careful ex- 
amination shows them to be Bidens frondosa L., a plant hitherto not 
reported from Southern California. Jepson (Erythea 1 :244, and Fl. 
W. Mid. .Cal.) reports it very common on the lower Sacramento 
River, but these are the only references I have found to the plant in 
this State. It may have come in from that region along the South- 
ern Pacific, or from the middle West along the Santa Fe. From the 
two widely separated stations it would seem to be well established 
and a probably permanent member of our flora.
