SMITH: STUDIES IN THE GENUS LUPINUS 72 
general discussion of L. densiflorus, so will not be repeated here. 
The description of Kellogg’s variety is as follows: 
Collected by Kellogg and Samuel Brannan, Jr., in Deer Valley, near Antioc 
San Joaquin River, April 22d, 1869; chiefly differing from the accepted description of 
the species—if we include also L. densiflorus—in the 2-toothed lower lip, relative 
length of leaves, and the entire scarious tube of the calyx, etc 
m fistulose, branching from near the axila]l summit, “leaflets about 10, one 
third the length of the ada Scan above, pubescent beneath, stipules and bracts 
ous, setaceously long acuminate, persistent; calyx tube scarious, upper lip 2- 
toothed, deflexed, somewhat saccate; vexillum short, rounded outline, pubescent on 
the back at the base, and along the claw above. Legumes hirsute, minute, 2-seeded.

As I have stated in the foregoing pages, I agree with others 
that L. Menziesii is not specifically distinct from L. densiflorus; 
but, on the other hand, I consider it a readily recognizable variety, 
from which I do not feel justified in trying to separate Kellogg’s 
var. aurea. The following description is supplementary to those 
given pi others: 
rs 14-15 mm. long; calyx rarely ( Heller'7439) bracteo- 
late, pstbabann & 9 mm., rarely 10 mm. long, upper lip variable in 
form, 2.5—3.5 mm. long, lower lip acute or Series as the tip and 
entire or two- to three-toothed, the teeth mostly less than I mm. 
long; petals bright yellow or paler, the apices and margins often 
washed with some shade of reddish purple; banner 12-14 mm. long, 
7-8 mm. ers rather abruptly contracted into a claw 4 mm. wide;
