30 Phacelia circinata Jacq. t". 



Described by .Pursh Fl., I, 140, as Phacelia heterophylla . " On the Koos- 

 kooskee, August 9, 1806 ; root fibrous, plant3 to 4 feet high ; dry situations." 

 Pursh says: "on dry hills on the banks of the Kooskooskee, July, August." 

 Only a few leaves and a portion of the flower branch have escaped the rava 

 ges of the beetles. The specimen from which Pursh took his description, 

 evidently, is in the herbarium of the Academy of Natural Sciences, under the 

 provisional name of Phacelia scabiosarfolia.
