described under that name, for a careful reading of his descrip- 

 tion shows lack of agreement in several particulars. 



Last summer while examining the lupines in the Gray Her- 

 barium, I came upon one of the originals, collected by Douglas, 

 upon which Agardh based his description, and saw at once that 

 it was a specimen of L. nanus. Later Miss Eastwood wrote 

 from Kew Gardens, England, saying that she had not only noted 

 the specimen in the Gray Herbarium, but had seen the type of 

 L. affinis^ and that it is the same as L. nanus. 



LUPINUS ONUSTUS Wats. Proc. Am. Acad. 11: 127. 1876. 



Lnpinus pinetoriim Jones, Cont. West. Bot. 8: 25. 1898. 



A growing suspicion that the above names represent but a 

 single species was confirmed during the past summer, when the 

 type of Watson's species was seen at the Gray Herbarium, and 

 that of Jones at the National Herbarium. At the latter place 

 there is also a co-type of L. onustiis^ giving ample opportunity 

 for comparison. The type of onustus was collected in Indian 

 valley, Plumas county, California, that of pinetoriim near Su- 

 sanville, Lassen county, northeast of Indian valley, but on the 

 east slope of the Sierra Nevada.
