Spiraea capitata, Fl. 342. 



Described from a specimen of Menzies from the northwest coast, 

 but of which he had said " an imperfect specimen gathered on the 

 Columbia River" by Lewis is not in the collection, nor in the her- 

 barium of the Academy, but is referred by Hooker to Neillia 

 thyrsijiora, and frequently noted in the Journal of the explorers as 

 " one of the Nine barks." 



Jussiaea subacaulis. PL, p. 304. 



Torrey and Gray, and Hooker refer this to Oenothera heterantha 

 Nutt. A specimen in the collection of the Academy, simply 

 marked " from Pursh's herbarium," is J. repens. As Pursh was 

 evidently well acquainted with all our Jussiseas, it seems incredible 

 that he should have mistaken an Oenothera for one of this genus. 



Symphoricarpos racemosus Mx. 

 Menziesia empetriformis Pursh. 



No specimen here or in the herbarium of the Academy. Hooker 

 supposes it to have been Cassiope Stelleriana, but Lewis reports his 

 plant from the Rocky Mountains, and near the mouth of the Colum- 

 bia River. 



Menziesia ferruginea Sni. 



" On the Columbia River, Lewis." June says Pursh. 



®Erigeron compositus, Fl. 535. 

 Pentstemon frutescens Lamb., Fl. 428. 

 :; Gerardia fruticosa Pursh. 



In the herbarium of the Academy his specimen is marked " G. 

 suffruticosa n. sp.," and has been placed by Dr. Gray on the sheet 

 with Pentstemon Menziesii Hooker. 



Mimulus Lewisii Pursh, 427. 

 Bartsia Gymnandra Pursh, 430. 



Dr. Gray suggests that Pursh's description indicates Synthyris 

 rubra. 



*Diotis lanata, Fl. 602. 



Is in herbarium of the Academy under Eurotla lanata. 



Lilium umbellatum Fl., 229. 



Hooker (Index Kewensis) suggests this may have been L. Phil- 

 adelphicum. 



Pinus taxifolia Lamb. FL, 640. 

 Pseudo- Tsuga Douglasii.
