‘LUPINUS. LEGUMINOS 4. 123 
late, rarely 1-foliolate, leaves, small stipules and mostly showy 
flowers in terminal racemes or spikes. Calyx deeply bilabiate, 
often 2-bracteolate; the upper lip 2-cleft or -toothed, or rarely 
entire, the lower entire or 3-toothed. Upper petal with the sides 
reflexed, the lateral ones foveolate-plicate toward the base, united 
at the summit, keel falcate, acuminate. Stamens monadelphous, 
the sheath entire ; alternate filaments longer; the 5 anthers op- 
posite the sepals oblong, maturing early, those opposite the pet- 
als roundish or reniform, maturing later. Stigma bearded: Pod 
coriaceous, somewhat oblong, more or less compressed, often 
torulose or intercepted with cellular partitions. Cotyledons fleshy. 
§ 1 Lupinus proper. Flowers in terminal racemes. Sides 
of the upper petal strongly reflexed. Ovary 5-12-ovuled. Cotyle- 
dons petioled after germination. 
* Perennial, shrubby, at least at base, tall, branched and leafy: pu- 
bescence silky, mostly appressed: leaflets 5-7: petioles rarely much 
exceeding the leaves; bracts deciduous; flowers large; lips of the 
calyx nearly equal: ovules 8-12. 
L. holosericeus Nutt. T. & G. Fl. i, 380. Frutescent, silvery-canes- 
cent: stems 12—20 inches high, leafy, branching, ascending: leaflets 
5—9, lanceolate, obtuse or acute, mucronulate, narrowed at base, often 
arcuate, densely silky-canescent and silvery on both sides, mostly 
shorter than the petiole or the upper ones as long or longer than the 
petiole: stipules subulate: flowers verticillate or somewhat scattered, 
approximate, on short pedicels: bracts lanceolate, shorter than the 
flowers: calyx bracteolate the upper lip slightly 2-cleft, the lower near- 
ly as long anu entire: petals vright blue, 6 lines long or more, the 
lateral ones broadly oblong. Islands and gravelly banks of the Wil- 
lamette river, to California. 
L. propingquus Greene Hryth. i, 126. Shrubby, much branched and 
bushy, usually 2—4 feet high, all the herbage except the glabrous up- 
per surface of the leaves puberulent; racemes short and short-ped- 
uncled, the flowers indistinctly whorled: bracts squarrose spreading, 
very caducous: lobes of the calyx subequal, the upper notched, often 
deeply so: petals 5 lines long, subequal, violet, the upper one redden- 
ing in age; keel strongly ciliate. In damp woods along the coast from 
Santa Barbara to Crescent City, California; no doubt on the coast of 
southern Oregon. — 
* * Perennials: stems wholly herbaceous, more or ‘ess eiongated. 
.*+ Leaflets glabrous above or nearly so, oblong or oblanceolate an 
inch or more long; stems mostly succulent and fistulous: flowers sub- 
verticillate: bracts deciduous: lips of the calyx usually but slightly 
toothed: ovules 8 or mure. 
L. Nootkatensis Donn Cat. Cant. Sims Bot. Mag. t. 1311. Stems 
often stout, 1—2 feet long, more or less decumbent, leafy: pubescence 
densely villous, spreading or subappressed: stipules elongated, setace- 
ous-acuminate: leaflets 6—8, cuneate-oblong, obtuse or acutish, mu- 
cronate, 1—2 inches long, about equalling the petiole: racemes elon- 
gated, nearly sessile: bracts linear-lanceolate, equalling the calyx: 
flowers blue or purplish, verticillate or scattered; pedicels 2—6 inches 
long; caryx large, with long setaceous bractlets, the upper lip rather 
deeply bifid and the lobes often erosely truncate, the lower one usual- 
ly strongly 3-toothed: petals 8—9 lines long, the keel a little shorter 
and usually naked: ovules 9—12: pods 18 lines long. Near the sea,
