11 Amelanchier alnifolia Nutt. 



"Service berry; a small bush. The narrows of the Columbia, April 15, 

 1806 " Pursh describes this, I, 340, as Pyrus sanguinea, and must have over- 

 looked this specimen. He quotes " in Canada and on the banks of the 

 Columbia, April, May." 



12 Crataegus Douglasii Lindley. 



" Deep purple Haw. Columbia Eiver, April 19, 1806." A mate to this 

 specimen is in the Herb. Ac. Nat. Sciences, labelled by Pursh " Crataegus 

 glandulosa" and described as such in Flora, I, 337. In the Journal dated 

 Fort Clatsop, January 20, 1806. The " brown haws berries growing 18 or 20 

 in a clump " must refer to this species. 



13 Geum triflorum Pursh. 



"On open ground, common on the waters of the Kooskooskee, June 12, 

 1806." The flowers are scarcely open. Pursh did not evidently recognize 

 it in this condition, but drew his description from a Bradbury Missouri 

 specimen. He probably had this specimen in mind when describing his Geum 

 ciliatum.
