and G. Riclianho/iii, 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. Richardsoiiii , but 

 scarcely pure white and with much more prominent veins. It 

 grows at an altitude of 1800—2700 m.

Lupinus candicans sp. nov. 



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 hght 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. serieeus and L. 

 Hellerae ; 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.
