In a wheat field near the village of Suisun, May 2, 1886, 

 growing with the common species, each plant forming a 

 compact, well rounded mass altogether intensely blue with 

 an extraordinary profusion of flowers. Tiie other three 

 species already recognized are almost impossible to dis- 

 tinguish, in herbarium specimens, but this, even when 

 dried, looks very different from those. Its cleft corolla- 

 tube is a new and unwelcome character, too much like 

 Lobelia.
