lupinus. LEGUMINOS.E. 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 1 

 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 ra*cemes. 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 somew T hat 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 ana entire: petals might blue, 6 lines long or more, the 

 lateral ones broadly oblong. Islands and gravelly banks of the Wil- 

 lamette river, to California. 



L. propinquus Greene Eryth. i, 12G. Shrubby, much branched and 

 bushy, usually 2 — 1 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 elongated. 



■+- 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. 



It. Nootkatensis Donn Cat. Cant. Sims Bot. Mag. t. 1311. Steins 

 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; caiyx 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.
