84 Alnhlenbergia, Volume 7 



Haplopappus paniculatus var. virgatus Gray. Two 

 specimens of this variety were collected in alkaline soil along 

 the margins of Dry lake, near Rosamond, in northwestern Los 

 Angeles county, in 1896, J. Biirtt-Davy 22^1^ 2g^2. In my 

 Compositae of Southern California it should stand next to H. 

 gossypinus^ from which it is readily distinguished by the strictly 

 racemose heads and distinct, green tips of the involucral bracts. 



Erigeron compositus Pursh. Summit of Mt. San Gor- 

 gonio, June 26, 1904, Mrs. C. M. Wilder. The rays are short 

 and pale, but very evident in some specimens. 



EcuPTA ALBA (L.) Hassk. On low land near Imperial, 

 December 11, 1907, Hall 8004, and Laguna ranch near Los 

 Angeles, December 19, 1907, Theodore Minthorn. This insig- 

 nificant annual may be distinguished from our other Helian- 

 theae by its involucral bracts, which are in two similar series. 



Trixis californica Kellogg, Proc. Cal. x\cad. 3: 182. f 

 ^j. 1862. This is the proper name for the only species of 

 Ti'ixis in southern California. It may be distinguished from T. 

 angustifolia by the glandular instead of tonientose lower surface 

 of the leaves. Our specimens are much paler than those from 

 Cedros Island, the type locality, but the two forms are evidently 

 conspecific. 



PiCRiS ECHioiDES L. Plentiful along ditches at Hunting- 

 ton beach, Orange county, 1909, Ira f. Gondii; also in the sub- 

 urbs of Los Angeles near Cienega, September, 1910, Theodore 

 Minthoi'n. An introduced weed resembling Sonchus^ but the 

 herbage bristly and the pappus plumose. 

 University of California, Berkeley, California.
