FIVE DWARF LUPINES 

 By Edward L. Greene 



, Lupinus fruticulosus 



Low diffuse undershnib, either fastigiately branched from 

 the base and 6 or 7 inches high, or more depressed and matted, 

 the mat 6 to 10 inches across: leaves many, small, but on long 

 slender petioles; leaflets 5 to 7, rather broadly oblanceolate, 

 acute, the largest onh' 2/^ inch long, the pubescence of both 

 faces rather short, silky, appressed, not so dense as to conceal 

 the green of the foliage altogether: racemes short, of 5 or 6 

 crowded verticils, but borne above the foliage on very slender 

 peduncles: corolla purph.-, the petals not unequal, the banner 

 broad and upright; keel with a margin of short dense implexed 

 wiiite wool: pod short, silky, i to 3-seeded. 



Apparently common in Klamath county, southern Oregon, 

 where it was gathered in the matted state by Coville and Ap- 

 plegate, 31 July, 1897, and in the more upright typical form by 

 Mrs. R. M. Austin, 9 August, also 1897. All give Annie Creek 

 Valley as the special habitat of this, which must be a handsome 

 species. 



Lupinus perditoriim 



Of the size of the last, the parts as slender, much more 

 loosely or not at all matted: leaflets y. inch long, oblong rather 

 than oblanceolate, the pubescence more scanty and less ap- 

 pressed: racemes narrow, more elongated, the small deep purple 

 flowers not in verticils: banner short, smaller than the very 

 broad and conspicuous wings; keel rather narrow and subfalcate, 

 shortly woolly-margined. 



In dry openings in woods along Rogue river, Jackson 

 county, Oregon, 8 July, 1898, E. I. Applegate; type on U. S. 

 Herbarium sheet j6t8ij. 



Lupinus abortivus 



Dwarf perennial, the very numerous branches densely 

 tufted on the shortly branched crown of a cylindrical taproot, 

 but all apparentlv suberect rather than at all depressed, 6 inches
