Arizona lupine is a branched, somewhat fleshy
annual from 12" to 24" tall with short-appressed and long-spreading
hairs. The leaves are glabrous above and villous beneath, and
have 5-10 oblanceolate leaflets rounded at the apex. The flowers
appear in an elongated raceme to 12" long and are somewhat whorled.
The banner and wings are dark pink to magenta, drying to violet
or whitish. There is a yellowish spot on the banner which ages
to a dark magenta. The upper keel margins are glabrous, the lower
ciliate near the tip. The fruit is a legume slightly less than
an inch long, 4-6 seeded, and coarsely hairy, and may predominate on
one side of the inflorescence axis. Arizona lupine blooms from
March to May, and is common in open sandy washes in both the Mojave
and Colorado Deserts below 2000'..
