THE NEVADA LUPINES— III 

 By A. A. Hellek 



(Continued from volume 5, page 153) 



Before taking up the subgenus Lupinus, I wish to thank 

 Dr. B. L. Robinson, of the Gray Herbarium, who has kindly 

 sent me fragments of several types, by means of which I have 

 been able to determine the flower structure of the species they 

 represent. In all cases they have proved to be distinct from 

 our Nevada plants, but without this confirmation it would be 

 unwise to form any definite opinion. I am also greatly indebted 

 to Miss Alice Eastwood, now working at the Gray Herbarium, 

 who has made critical examination of a number of types and 

 compared specimens sent by me with them, and has generously 

 aided me in every way possible. To Dr. H. M. Hall, of the 

 University of California, I am also indebted for the loan of ex- 

 tensive suites of specimens from their herbarium, and which 

 have been consulted in the preparation of this paper. 



The annual lupines are comparatively easy to define in a 

 satisfactory way, but when one takes up the perennials he en- 

 counters a much more complicated problem. In the treatment 

 of these there will probably be considerable difference of opin- 

 ion, for there is here an opportunity for either much "lumping" 

 or much "splitting." Environment seems to play an important 

 part in their development. I use the word "seems" advisedly, 

 for little is known about the subject, and only an opinion can be 

 given, unsupported by actual knowledge. 



After a number of years have been spent in experimenting 

 with plants that have been transposed from low to high altitu-
