No. 7692, collected April 14, at Randsburg, Kern county, 

 where it is abundant on stony hillsides. The flowers are open 

 both day and night apparently, since it was collected late in the 

 evening, was open early the next morning, and continued open 

 during the whole morning. Our specimens very much resem- 

 ble the plate in the Botanical Register, although some parts of 

 the description do not accord. But they are totally different 

 from the Mentzelia Liftdleyi of the Bay region, and supposedly 

 from the region where Douglas obtained the type.

No. 7913, collected May 31, on the hills not far from Kes- 

 wick, Shasta county, growing in moist ground near a small 

 stream. In habit and form of leaves this is much like the figure 

 of the original, but the flowers are fewer and smaller. Strictly 

 typical specimens of this species are rare, there being only one 

 or two in the herbarium, of the California Academy of Sciences 

 which closely approach it.
