cled and dense ; bracts ovate-lanceolate, acuminate, deciduous ; 

 the short pedicels and the calyx densely pubescent with short 

 spreading hairs ; lips of the calyx ovate-lanceolate, the lower 

 slightly longer than the upper: flowers 10-12 mm. long; banner 

 light purple with a dark spot, glabrous, much shorter than the 

 white or purple-tinged wings ; keel white with purple tip : pods 

 oblong, densely pubescent, 2.5-3 cm. long, 4-5-seeded. 



The type was labeled Luphms parvifloj^iis, to which it is some- 

 what related, but the raceme is much denser, the flowers larger, 

 the corolla of a different color and with a very dark spot.

Lupinus pulcherrimus sp. nov. 



Perennial, more or less cespitose : stems 3-6 dm. high, spar- 

 ingly appressed hairy, leafy : petioles 3-6 cm. long, also appressed 

 hairy or glabrate ; leaflets 7-9, linear-oblanceolate, acute, appressed 

 silky on both sides, but green ; stipules lanceolate, subulate : raceme 

 more or less elongated and rather dense, short-peduncled ; bracts 

 lanceolate, short-acuminate, shorter than the buds, deciduous : 

 pedicels and calyx grayish silky ; lips of the latter lanceolate, the 

 upper somewhat shorter : flower about i cm. long : corolla dark 

 purple ; banner with a light spot, pubescent on the back : pods 

 broadly oblong, 3-3.5 cm. long, 5-6-seeded. 



This species is also related to L. laxiflonis, but the raceme is 

 denser, the calyx scarcely spurred, and the flowers are larger. It 

 also resembles L. pseudopai'viflorus, but in that species the leaves are 

 glabrous above and the calyx also spurred. From L. adsccndens 

 it differs in the spreading flowers and the short bracts.
