134 PITTONIA. 
“Lupinus HELLERI. Perennial, the rather rigid suberect 
scarcely branching stems 2 or 3 feet high inclusive of the 
rather elongated and showy subsessile raceme, the whole 
herbage silvery-canescent with a very fine appressed-silky 
indument: leaflets 7 to 9, about 14 inches long, oblanceo- 
late-linear, acute, apt to be conduplicate, the upper face 
greener and more sparsely silky-hairy: solitary raceme 6 
to 10 inches long exclusive of the short peduncle, in its un- 
developed state showing an imbricated series of ovate-lan- 
ceolate acuminate erect and closely appressed bracts ; flowers 
scarcely whorled; calyx densely silky, very distinctly 
spurred; petals blue-purple, subequal, about 5 lines long, 
the banner with a few silky hairs on the middle of the back; 
keel somewhat falcate, scantily ciliate in the middle and 
toward the apex with tortuous hairs. 
This is Mr. Heller’s number 3557 of my set of his New- 
Mexican plants of 1897, taken from “a cafion one mile 
southeast of Santa Fé,” and distributed for “L. argenteus," a 
Purshian species of most uncertain identity, never ade- 
quately described by that author, nor positively identified 
by any subsequent writers on our lupines, on which ac- 
count the name itself ought to be dropped. Mr. Heller's 
plants differ specifically from the common L. decumbens of 
Rocky Mountain plains and hills by its eanescent silkiness, 
unbranching stems, longer raceme of larger flowers, and its 
spurred calyx. 
LUPINUS wYRrANTHUs. Size of the last, but the stems 
freely branching above and the racemes several, very dense 
and the flowers of the smallest; stem purplish and only 
sparsely strigulose; petioles slender and the 7 to 9 leaflets 
narrowly oblanceolate, acutish, perfectly glabrous above, 
finely and rather densely strigulose beneath: racemes 2 to 
9 inches long, subsessile, in bud showing bracts with atten- 
uate and spreading tips; flowers violet, verticillate but the 
whorls closely contiguous; pedicels and calyx densely vil-
