and G. RicJiardsoiiii, having the general habit, the leaves and pu- 

 bescence of the stem of the latter, but the densely glandular pu- 

 bescence of the inflorescence and the calyx and carpels of the 

 former. The color of the flower is most like G. RicJiardsonii, but 

 scarcely pure white and with much more prominent veins. It 

 grows at an altitude of 1800-2700 m.

Lupinus candicans sp. no v. 



A low cespitose perennial, densely white-silky throughout. 

 Stems ascending, 1.5-2 dm. high, 3-4-leaved, often branched: 

 stipules linear subulate, 5-8 mm. long : petiole 3-8 cm. long : leaf- 

 lets about 7, densely white-silky and shining, 1.5-2.5 cm. long, 

 oblanceolate, acute, mucronate, mostly conduplicate : raceme rather 

 dense, 3-8 cm. long on a peduncle 2-5 cm. long : bracts small 

 and early deciduous : calyx densely silky-villous, only slightly 

 saccate on the upper side ; lower lobe about 4 mm. long : banner 

 dark blue with a light brown spot, about 7 mm. long, very broad, 

 and with the sides strongly reflexed ; wings dark blue, as well as 

 the banner glabrous, about 9 mm. long and about equaling the 

 keel : the latter whitish, tipped with dark purple : pod densely 

 white-silky, 3— 4-seeded. 



This species has the white pubescence of L. scricens and L. 

 Hcllerae ; but is in every way a much smaller and more cespitose 

 plant : the flowers are much smaller and of a darker and more in- 

 tense blue.
