406 SMITH: STUDIES IN THE GENUS LUPINUS 
foliolis 6-10, 20-30 cm. longis, oblanceolatis, apice obtusis vel 
rotundatis, subter laxe villosis; pedunculis elongatis, verticillis 
3-7, distantibus; floribus ad anthesin postea pandentibus ascen- 
dentibus vel suberectis, 14-16 mm. longis; pedicellis prope I mm. 
longis, robustis; bracteis villosis, vix 10 mm. longis: calyce ebracte- 
olato, prope 10 mm. longo, subter villoso pilis prope 1.5 mm. longis, 
labio superiore diverso prope 2 mm. longo, inferiore inflato 3.5-4 
mm. lato, 2-dentato, sinu dentis vestigio instructo vel sine eodem, 
dentibus vix 1 mm. longis; corolla atro-purpurea praesertim vexilli 
alarumque dimidiis terminatis; vexillo apice rotundato 13-15 mm 
longo, 8 mm. lato, abrupte contracto ungue 4-5 mm. lato; alis 
I1~13 mm. longis, ad basin super frequenter non ciliatis; carina 
10-11 mm. longa suberecta vel aliquantum curvata; leguminibus 
prope 12 mm. longis: semina non vidi. 
Simple or branched, loosely villous, the hairs 2-4 mm. long; 
whorls three to seven, well-separated ; flowers spreading in anthesis, 
evidently ascending to suberect later; calyx ebracteolate, quite 
villous below; pods not secund. The typical plant has the lower lip 
of the calyx evidently inflated (subsaccate) near the base, large 
flowers with much of the banner and wings dark purple, and the 
banner rounded apically. Most of the varieties have the lower 
calyx-lip scarcely or not at all inflated and smaller flowers with 
the banner gradually narrowed to an acute apex. 
The type is Heller & Brown 5415, collected near Madison, Yolo 
county, California, April 29, 1902, sheet 9586 in the Dudley 
Herbarium of Stanford University. 
Descriptions of the varieties recognized, distribution, full cita- 
tions of specimens determined, keys, and figures of floral parts will 
be given in the main paper when finally published.
