This has queer-looking flowers and is conspicuous on that account. The branching stems are a foot or more tall, the stipules are large, with papery margins, and the leaves are bright green, with a paler spot near the middle of each of the leaflets, which are toothed, or sometimes only bristly on the edges, and the flowers form a head about an inch and a quarter across, with a broad involucre. The calyx is very small and the corolla is cream-color, becoming much inflated and changing to deep pink as the flower withers. The effect of the cluster is curiously puffy and odd in color. This grows rankly in low alkaline and brackish places.
There are many kinds of Psoralea, widely distributed; ours are perennial herbs, without tendrils, the leaves with three or five leaflets, with glandular dots on them and usually bad-smelling. The flowers are white or purplish, and the pod is short, with only one seed.

This is a rather pleasing plant, for the foliage is pretty, though the flowers are too dull in color to be effective. It is almost smooth all over, a foot or more tall, with several spreading stems and rich green leaves, thin in texture and giving out a rather pleasant aromatic smell when crushed. The flowers are less than half an inch long, with a somewhat hairy calyx, covered with dots and becoming inflated in fruit, and a yellowish-white corolla, more or less tinged with purple. This is common in the woods of the Coast Ranges. The foliage was used as tea by the early settlers.

There are many kinds of Cytisus, natives of Europe, Asia, and Africa, named for Cythrus, one of the Cyclades, where the first species was found.

A handsome branching shrub, about five feet high, with almost smooth or quite hairy leaves, with three, toothless leaflets, and fine clusters of flowers, each an inch or more long, with a yellow two-lipped calyx and a golden-yellow corolla, deeper in color at the base of the standard and at the tips of the wings; the stamens ten, in one set; the style curved in. The pod is flat, smooth on the sides, but hairy along the edges, one or two inches long and curling when ripe. This is said to have been brought to California by Cornish miners.
