ploughing the sand for a homestead. Brachyactis frondosm and 

 Polypogon monspeliensis seem to find a congenial home in the 



drain ditches where it is more or less moist and alkaline. 



Two species of Erwgonum, E. Baileyi and the so called E. 

 angulosum^ are occasionally met with in patches on sandy land. 

 Cleomft httitu Solatium triflorum and Chenopodium Botrys grow 

 as weeds alon«- the irrigation canals. Euthamia occidenialis is 

 abundant, along the old irrigation ditches. 



Aniong the most ornamental annuals are the sand verbenas, 

 Abronia crux maltae and A. turbinata. The mallows are 

 represented by three species, an orange-red Spliacralcca, S. am- 

 bigita, and two weeds, Malva rotundifolia and M. parvijlma. 

 The only cactus that we know of in the region is Opuniiapul- 

 chella. 



NOTES ON THE FLORA OF NEVADA— III 

 By A. a. Heller 



Lepidium perfoliatum L. Sp. PI. 643. 1 753- 

 Early in May, 1909, I chanced upon this curious crucifer 

 while waiting for train connections at Derby, a way station some 

 miles east of Reno. Two plants only were found growing in 

 the cinders along the track. A search in our manuals and other 

 books failed to identify it specifically, nor could it be found in 

 Bentham and Hooker's British Botany. 



Late in May of the present year I found it growing rather 

 plentifully along the railroad at Hood River, Oregon, and had 

 it named for me by Mr. M. W. Gorman, of Portland. Later it 

 was found in quantity along the railroad at Pendleton, Oregon. 

 Shortly afterward Professor C. P. Smith, of the I'lah Agricul- 

 tural College told me that it has also'been found in Utah, and I 

 think showed me specimens collected by himself. Since that I 

 have seen plants collected near Salt Lake City by Mrs. Joseph 

 Clemens. A specimen was brought in during the summer by 

 Mr. C. L. Brown, who found it on Virginia street. Reno.
