 on Santa Margarita Island, and much smaller at Llano de

Sph^ralcea Coulteri Watson. Differs from the described 

 form only in its larger leaves, strictly annual habit and 

 rather larger orange-yellow flowers. The horizontal pro-

 tion. This plant is extremel}^ abundant during the months 

 of February and March in the southern region. On Santa 

 Margarita Island it becomes four feet high, and covers 

 large areas to the exclusion of other vegetation. In April 

 it dries up and disappears. -
