Bentham lupine is an erect villous annual to
2' tall with stout, simple to branched stems and slender petioles, leaves
with 7-10 linear leaflets that look somewhat like spiders (hence another
common name, spider lupine), and long racemes of ± whorled flowers.
The blooms are deep blue with a yellow or whitish spot on the banner
and a keel the upper margin of which is glabrous and the lower ciliate
near the base. The ascending seed pods are 1" to 1-1/2"
long, coarsely hairy and contain 3-9 seeds. This lovely lupine
occupies open to rocky slopes below about 4000' in valley grassland
and foothill woodland from n. Los Angeles Co. and Kern Co. north, and
areas of the nw Mojave Desert. It blooms from March to May. These
pictures were taken in the Antelope Valley.
