154 Muhlenbergia, Volume ^ 



Anisocarpus radiatus (Kellogg) Greene, Fl. Franc. 416. 1897. 



Madia radiata Kellogg, Proc. Cal, Acad. 4: 190. 1873. 



No. 7782, collected April 28, on the high ridge west of 

 McKittrick, Kern county, on rich grassy slopes. The speci- 

 mens were collected between 4 and 5 o'clock in the afternoon, 

 the flowers fully open, which would tend to confirm the state- 

 ment that the species in this genus and its relatives are vesper- 

 tine. We know from personal observation that such is not the 

 case with Madia saliva^ which expands its flowers about day- 

 break and closes them about 9 o'clock, and suspect the same is 

 true of the species of Madaria.
