Los Angeles, Santa Monica and San Diego. About the latter 

 city it is perhaps the most abundant plant of waysides and 

 waste grounds. 



Cycloloma atriplicifolia Coulter 



Collected in 1909 by Mrs. C. M. Wilder, as a waif, along a 

 road between Colton and Bloomington, and in July, 1914, by 

 Parish (No. 9500) in the same locality, where it is now abun- 

 dant and well established. 



Batis maritimum Linn. 



Abundant on dykes and banks of the salt marshes of False 

 Bay, San Diego. Near Old Town, September, 1913, Parish 

 8721. 



Diplotaxis muralis Linn. 



This European weed is well established along a street in 

 San Bernardino, where it was first seen in July, 1914 (Parish 

 9502), being the first authentic collection reported from the 

 state. In Davidson's Plants of Los Angeles County (1896) it 

 is entered as from Los Angeles and Redondo, but in the Bulle- 

 tin of the Southern California Academy of Sciences 2:29 (1903) 

 it is corrected to D. tenuifolia DC, which has also been col- 

 lected at Pasadena, by Grant. 



Lepidium perfoliatum Linn. 



This Eurasian weed is a recent immigrant to the United 

 States, and so far as reports indicate is, as yet, confined to the 

 western states. Its first reported appearance was at Salt Lake, 

 in 1908, and five years later it was reported by Garrett (Torreya 

 13 :238) as abundant in that vicinity. In May, 1909, two plants 

 were found by Heller growing in cinders along the railway 

 track at Derby, a few miles west of Reno, Nevada ; the follow- 

 ing May he found it "growing rather plentifully along the i-ail- 

 road at Hood River, and in quantity at Pendleton," both in 

 Oregon; and the same summer a specimen was found by the 

 wayside at Reno (Muhlenb. 6:92), where it is now abundant. 

 Davidson (Bull. S. Cal. Acad. 10:11) reported a few plants 

 appearing at Hollywood in 1910, and (lb. 13:14) at Annandale, 

 both suburbs of Los Angeles. In May, 1913, two or three 

 plants were collected by IMrs. M. F. Bradshaw at Orange, and 

 in April, 1914, a single specimen was found by Parish at Point 

 Loma, near San Diego. It has also made its appearance at a 

 few places in central California. In 1912 Rattan got it in the 

 Grand Cation, Arizona. As yet it has not found a place in 

 American Floras, but it may be readily recognized by its 

 dimorphous leaves, the basal finely pinnatly dissected and ap- 

 proximate, and the rameal bractlike, entire, and so broadly 

 auriculate as to appear perfoliate. Heller, 1. c. gives a good 

 plate of the plant.
