[Label only]. The root not 

 eaten by the natives. On the 

 Columbia, April 14, 1806. 



[Sterile and unidentified. 

 Stem lignescent, leaves opposite, 

 narrow, linear, fascicled in axils]. 

 A shrub about 4 feet high. On 

 the plains of the Columbia. 

 May 7, 1806. Identified while the 

 mss. was going through the press, 

 by Prof. Heller of the University 

 of Minnesota, as Phlox speciosa 

 Pursh. See Flora, P. 149. 



To the above detail by Dr. Robinson and Mr. Greenman, it 

 may now be noted that this collection contains specimens of 

 all but sixteen of Lewis's plants as described by Pursh in his 

 Flora. Of these sixteen, seven, as marked with an asterisk, are 

 represented already in the specimens from Lambert's herbarium, 

 leaving but nine of the plants missing from the collection as described 

 by Pursh. Only a few of these nine missing ones are of material 

 importance. For all practical purposes, all the plants of Lewis 

 and Clark's expedition are now deposited in the Academy. 



*Berberis Aquifolium Pursh. 

 *Berberis nervosa Pursh. 

 *Ceanothus sanguineus Pursh. 



Under the provisional name of " C. atropurpureus" 

 *Psoralea esculenta Pursh. 



In the Journal of the expedition, under date of August 10th, it 

 is noted " at the confluence of the Yellowstone with the Missouri, 

 Captain Clark found to day * * the men also dug up large 

 quantities of a large and very insipid root called by the Indians 

 Hankee, and by the ' engages ' ' white apple.' It is used by them 

 in a dry and powdered state, but our men boiled it and ate it with 

 their meat." 



On the same sheet with Psoralea esculenta Pursh has fastened down 

 a specimen of P. hypogoza Nutt., not noting its distinction. The ini- 

 tials of Professor Britton are under it with this correction : It was 

 evidently collected on the headwaters of the Platte, where Nuttall 

 subsequently found it.
