to L. micensu in either general appearance or described charac- 

 ters. Its true relationship is with L. concinnus, and it was my 

 intention, for a time, to put it down as a synonym of that spe- 

 cies. But until I have an opportunity to examine typical ma- 

 terial of L. concinnus, which, Miss Eastwood informs me, was 

 undoubtedly collected in southern Monterey county, California, 

 in the Santa Lucia mountains, I shall treat it as distinct. 



A careful examination of abundant material from Cali- 

 fornia, Arizona and New Mexico, labeled L. concinnns, shows 

 several marked forms. The plants all agree fairly well in habit 

 and pubescence, but there is a noticeable difference in the size 

 and color of the flowers, and in their arrangement. Dissection 

 reveals the fact that there is also a marked difference in the 

 shape of the floral parts. There likewise seems to be a corres- 

 ponding diversity in the seeds. I should esteem it a great favor 

 if both specimens and seeds of what is supposed to be L. concin- 

 nns be sent to me from as many sources as possible. 



POLYPHYI.LI 



Both of the species included under this section were origi- 

 nally distributed by Professor C. F. Baker, under the names 

 here proposed, with Dr. E. L. Greene as authority. They have 

 stood as herbarium names for the past eight years, and are now 

 published with Dr. Greene's consent. L. longipes might be ex- 

 pected to occur in Nevada, but whether it descends to the east- 

 ern side of the Sierra is doubtful. One distinguishing feature 

 of that species is a brown seed with a dark diagonal line. 



Lupinus eloiigutus Greene, n. sp. 

 Herbaceous perennial: stems numerous from a thick root- 

 stock, 9 dm. high or less, stout, often 1 cm. across near the base, 

 hollow and somewhat succulent, glabrous to the naked eye, but 

 sparingly pubescent with short appressed hairs, especially above, 

 greenish-yellow or purplish: petioles of the lower leaves very 

 long, often 2 dm. or more, dilated at base, those of the other 

 leaves successively shorter; stipules of the lower leaves 2 to 3cm. 

 long, a little more than 1 mm. wide, adnate to the petiole for 

 three-fourths theri length, the free portion lance-subulate, some-
