344 Henderson : New Plants from the Northwest 



appressed silky-canescent on both sides ; cauline leaves 2 or 3, 

 with shorter or very short petioles : stipules adnate, subulate : 

 raceme dense, cylindric, 8—9 cm. long by 2 cm. wide : bracts per- 

 sistent, exserted and recurved before anthesis, in anthesis equaling 

 the calyx, lanceolate to narrowly subulate : flowers 7-8 mm. long, 

 on pedicels less then 2 mm. long, sub-verticillate : calyx silky, 

 with subequal lips and very small bractlets ; the lower lip entire, 

 the upper cleft for two-thirds its length : standard obovate to or- 

 bicular, silky, reflexed : keel short-pointed, ciliate : ovary 3-4 

 seeded, silky: pod unknown. 



Differs from Z. canescens Howell, in much smaller stature, 

 fewer flowers, leaflets not densely appressed, and shorter racemes. 

 From L. lepidus it differs in not being densely silky, bracts per- 

 sistent, banner silky, shorter pedicels, entire lower calyx-lip, flow- 

 ers smaller, and ovules fewer. From L. confertits it differs in less 

 branching character, shorter pubescence, shorter peduncle, entire 

 lower calyx-lip, smaller petals, not narrowly ovate but obovate 

 orbicular silky banner. 



No. 3088. Rather dry ground, Long Valley, Boise County,

Lupinus retiorsus 



Perennial, 6-9 dm. high, erect, simple or branching, softly 

 hispid-villous with spreading or strongly retrorse white hairs, leafy, 

 rather long-peduncled : leaves with retrorsely hispid petioles ; leaf- 

 lets from as long to half as long as the petioles, greenish villous 

 above, whitish villous below, 4-7 cm. long, narrowly oblanceolate, 

 acuminate or merely acute ; stipules long setaceous, silky within, 

 hispid without : raceme from 6 cm. in length when in flower to 30 

 cm. in fruit, densely flowered but verticillate, apparently few pods 

 maturing : bracts quite persistent, long subulate-aristate, hispid, 

 longer than the buds and many of the flowers : pedicels 1-4 mm. 

 long, with the calyx very villous: flowers 8-12 mm. long: calyx 

 broad at base, slightly saccate, shortly bracteolate, with upper lip 

 broad, shorter then the lower, and cleft into two short broad lobes ; 

 lower lip broad, subentire, or with 3 short lobes ; banner hairy, 

 broadly obovate, rather retuse from the slightly cohering sides : 

 keel ciliate, rather shortly pointed : pod densely villous with white 

 hairs, 2 cm. long, ripening 3-4 of the 5-6 ovules : seeds small, 

 pinkish-brown and mottled with small brown spots.
