188 SMITH: STUDIES IN THE GENUS LUPINUS 
mm. latis, ad basin subter manifeste ciliatis; carina subrecta, vel 
paulo curvata II-I2 mm 
This variety of the San Saar in Valley and adjacent foothills 
of the Sierras differs from var. Dudleyi in the shorter pubescence 
of the calyx, the usually more richly tinted corollas, and the de- 
cided prevalence of interstitial bracteoles. While seeds of var. 
Dudleyi have not yet been seen by me, I have no doubt but that 
such will be found to differ considerably from those of var. ver- 
sabilis. Seeds with the San Joaquin County plant, cited below, 
are milky-white, unmarked, rather smooth and plump, about 
5x4 mm.

Versabilis is Latin for ‘‘ changeable” and refers to the variation 
in the tinting of the petals. 
6n. Lupinus densiflorus latidens var. nov. [Fic. 31.] 
Habitu notisque var. versabilis, a ipso differt pilis pandentibus 
plurimum laxe vix 0.3-0.5 mm. longis; labio calycis inferiore 
interdum integro vel 2—3-dentato, dentibus vegans latioribus 
quam longis; leguminibus secundis prope 15 mm. long 
Differing from var. versabilis in the somewhat eet pubes- 
cence, in the paler tinting of the petals, as a rule, and the lower 
calyx-lip being entire or with very wide short teeth. It seems to 
be local in the general vicinity of San Bernardino.
