Lupinus stenophyllus (Nutt.) 
Lupinus foliosus stenophyllus Nutt.; T. & G. Fl. N. Am. 1: 377 
(synonym). 1840. 
Stem slender, probably 1 m. high, finely silky-strigose ; stipules 
small, subulate; petioles of the stem-leaves about 3 cm. long, 
strigose ; leaflets about 5, narrowly linear-oblanceolate, about 3 cm. 
long, 4 mm. wide, usually conduplicate, acute, green, glabrous 
above, sparingly silky-strigose beneath; raceme about 1 dm. long, 
lax, more or less one-sided; bracts lanceolate, shorter than the 
calyx, deciduous; calyx densely silky-strigose, more or less 
spurred at the base; upper lip ovate, 4 mm. long, the lower 
lanceolate, 6 mm. long; corolla light-blue, 7-8 mm. long ; banner 
slightly shorter than the broad wings; fruit unknown. 
This species has been included in L. /aviflorus and L. tenellus. 
It resembles the latter in habit but differs in the spurred calyx and 
green leaves. From the former it differs in the narrower leaves, 
glabrous above, and the smaller flowers. The type was collected 
on the “ Oregon Plains” by Nuttall. 
Lupinus laxispicatus 
Perennial ; stems 3-4 dm. high, slender, striate, sparingly 
strigose ; stipules small, lanceolate ; petioles strigose, 5-15 ¢™- 
ong; leaflets 7-10, narrowly oblanceolate, acute, green, glabrous 
above, strigose beneath, 4—5 cm. long, about 6 mm. wide ; inflor- 
escence lax, rather few-flowered ; bracts lanceolate, shorter than 
the calyx, deciduous ; calyx grayish silky-strigose, gibbous; lips 
lanceolate, the upper 6 mm., the lower 7 mm. long; corolla blue, 
about 10 mm. long; banner only slightly shorter than the wing> 
This species is nearest related to L. Scheuberae, which however 
has broader leaves, larger flowers and the upper lip of the calyx 
is ovate and much shorter than the lower. L. laxispicatus grows 
on high mountains,
