MUHLENBERGIA 



THE NORTH AMERCAN LUPINES— VI. 



Bv A. A. Heller 



POLYPHYLLi Heller, Muhlenbergia 6: 15. 1910. 



My description of this section must be emended in one re- 

 spect. The basal leaves are not always long petioled, for in cer- 

 tain members of the group, as L. procerus, they are short, only 

 I dm. long. The stems are simple. Agardh, Synopsis 16, de- 

 scribes a tribe Polyphylli, but includes in it such species as 

 minimus and lepidus, which are not at all related \o polyphyllus. 

 He also puts here latifolius and cytisoides, but these in tny opin- 

 ion should go into another section. 



The Polyphylli as a whole are moisture loving plants, and 

 are commonly found in swampy places, in moist meadows, or on 

 stream banks close to the water. L. polyphyllus itself often acts 

 at variance with this rule, growing on grassy slopes away from 

 water, but it occurs in a region where there is an abundant rain- 

 fall, and apparently dues not need the extra moisture. The 

 members of this .'section are widely distributed, occurring from 

 the immediate vicinity of the Pacific coast to the Rocky moun- 

 tain region. The following species belong to this section: 



LuPiNUS APODOTROPLS Heller, Muhlenbergia T : 14. 191 1. 

 Eastern Oregon. 



]/ Lupinus barbatiis (Hender.«;on) 



Lupinus ligulatus harbatus Henderson, Bull. Torr. Club 



5i7: 345. 1900. 

 The type of this plant, in the Gray Herbarium, is certainly 

 distinct from L. lis^uJntus. Southern Oregon.
