I'm going to say the hairs on those bracts are "long-spreading" (var. densiflorus), rather than "long-shaggy" (var. microcarpus). The color is certainly more consistent with densiflorus. (Quotes from keys in Matthews/Mitchell).

Chick Lupine (Lupinus microcarpus) Native, annual plant that prefers clay soils and grows along road sides. It's the only CA lupine with predominantly white/cream colored flowers. All plant parts have sparse, appressed to spreading hairs. Upper keel margins are hairy near claw. Peak bloom time: April-May.

Pea Family (Fabaceae). The Pea family has 5-petaled flowers, consisting of a wide upper banner petal, two wing petals, plus two lower petals which are fused to form a boat-shaped keel. Many produce heads or spikes, consisting of multiple individual flowers (examples are lupines and clovers). The seed pod is generally a “legume”; a long, flattish pod, swollen by the seeds, and splitting lengthwise along both the top and bottom.

"Most lupines have distinct clusters of flowers in spikes, sometimes short, sometimes quite tall. Leaves are typically palmately compound, with leaflets ranging from very narrow to broad. It is useful to note whether the flowers are in whorls around the stem. It can also be critical to look at the keel, to see the pattern of hairs. Some are ciliate on both the top and bottom of the keel; some have hairs only near the claw (base), others only near the tip."

Lupine I.D. Tips and Links by INat yerbasanta :
1) Reveal and photograph the keel petal (hidden within the wings) to document the hairs (if any) on the upper and lower surface along the entire length.
