Chaparral Pea
Xylothérmia montàna (Pickeringia)
Crimson
Spring, summer
California
This is the only kind, an evergreen shrub, flourishing on dry hills in the Coast Ranges, with tough, crooked branches and stout spines, forming chaparral so dense that it is impossible to penetrate. It grows from three to eight feet high, the gnarled, knotty, black branches terminating in long spines, which are often clothed with small leaves nearly to the end, the leaves with one to three, small leaflets and without stipules. The bush is often covered with quantities of pretty, bright, deep purplish-pink flowers, three-quarters of an inch long, forming a fine mass of color. The calyx has four, short, broad teeth; the petals are equal, the standard roundish, with the sides turned back and a paler spot at base, the wings oblong, the keel straight; the filaments of the ten stamens not united; the pod is two inches long, flat, straight, sickle-shaped when young. This very rarely produces fruit. Stevenson was probably describing this shrub when he wrote, "Even the low thorny chaparral was thick with pea-like blossoms."
Parosela Californica.
Chaparral Pea—Xylothermia montana.
Parosela Emoryi.
There are so many western kinds of Lupinus that it is hopeless for the amateur to distinguish them; herbs, sometimes shrubs; leaves palmately-compound, stipules adhering to the base of the leaf-stalk, leaflets, more than three in number, usually closing at mid-day; flowers showy, in terminal racemes; calyx deeply toothed, two-lipped; standard broad, the edges rolling back, wings lightly adhering above, enclosing the incurved, pointed keel, sometimes beaked; style incurved, stigma bearded; stamens united by their filaments, alternate anthers shorter; pod two-valved, leathery, flat, oblong; seeds two to twelve. Lupines always have palmately-divided leaves, and are never trailing, twining, or tendril-bearing and thus may be superficially distinguished from Vetches and Peas, and from Thermopsis, by the united stamens.

Lupìnus rivulàris
Blue and white and purple
Summer
Northwest
A stately perennial, about three feet high, with stout, branching reddish, slightly downy stems, bearing several tall spires of flowers. The handsome leaves are bright green, smooth on the upper side, slightly downy, but not silvery, on the under, with from seven to thirteen leaflets, and the flower-cluster is very erect and compact, eight or ten inches long, beautifully shaded in color, from the pale, silky buds at the tip, to the blue and purple of the open flowers, which are about five-eighths of an inch long, with a lilac standard, tipped with purple. The upper flowers have white wings, veined with blue, and a green calyx, with reddish teeth, and the lower flowers have bright blue wings, veined with purple, and a reddish-purple calyx. This grows in wet places.
Tree Lupine
Lupìnus arbòreus
Yellow
Spring
California
A conspicuous shrub, four to eight feet high, with a thick trunk, gnarled and twisted below, with purplish, downy branches, silvery twigs and dull bluish-green leaves, downy on the under side, with about nine leaflets. The fine flower clusters are sometimes a foot long, composed of beautiful canary-yellow flowers, deliciously sweet-scented. This is easily recognized by its size and fragrance and is common in sandy soil near the sea, where it has been found very useful, as its very long roots keep the sand dunes from shifting.
