MUHLENBERGIA 



THE NORTH AMERICAN LUPINES— HI 

 By a. a. Heller 



A few days ago while referring to a letter written me by 

 Dr. Greene, I discovered that one sentence had been carelessly 

 read by me, and therefore I owe an apology to both Dr. Greene 

 and Professor C. P. Smith. The passage is as follows: 



"Lately I was well on the road to a description of a Califor- 

 nian annual species, which is here under the name of "Z. apri- 

 cusy I saw it was not at all that, and hunting further, I dis- 

 covered that the thing had been published by you quite a while 

 ago; your L. persistens'''' {vallicola). 



Now, what I thought at the time, was that Dr. Greene con- 

 sidered apricHS to be the same as my vallicola, and so informed 

 Professor Smith. This should clear up the difficulty mentioned 

 by him on page 135 of volume 6. 



The latter part of May and a few days of early June, 1910, 

 were spent by me.- in that wonderful country first made known 

 botanically by Captain Meriwether Lewis, and a little later, but 

 now nearly a century past, by that hardy explorer, David Doug- 

 las, who first discovered so many of our Pacific coast species. I 

 refer to the Columbia river region. My main object was to 

 study lupines at the places where Douglas collected his types, 

 and this I was able to do in a satisfactory way, although it is 

 necessary to spend several seasons there to cover all the ground. 

 Among the species of which dependable material was obtained 

 are L. micranthiis, bicolor^ leiicophylliis^ pliimosiis, polyphyllus 

 and sulphureus. Two of these are treated in this paper, and the 

 others will be mentioned later.
