Spring

Arizona=]

An attractive plant, about a foot high, with straggling, reddish stems

and delicate foliage. The flowers are over half an inch long, with a

hairy calyx and pale lilac and white corolla, and form pretty clusters

about two inches long.

There are many kinds of Hedysarum, some from Africa and only a few

in this country; perennial herbs, sometimes shrubby; the leaflets

toothless, odd in number; the flowers in handsome racemes, with

bracts, on stalks from the angles of the stem; the calyx with five,

nearly equal teeth; the standard rather large, round, or inverted

heart-shaped, narrow at base, the wings oblong, shorter than the

standard; the keel blunt, nearly straight, longer than the wings; the

stamens in two sets of nine and one, not adhering to the corolla;

the pod long, flat, and oddly jointed into several, strongly-veined,

one-seeded, roundish divisions, which separate when ripe. The name is

from the Greek, meaning "sweet-broom."

Utah=]

A very handsome and decorative plant, with large brilliant

flower-clusters, contrasting well with the foliage and making spots of

vivid color on dry plains and hillsides. It has many stems, springing

from a rootstock, which are from eight to fifteen inches long,

yellowish-green, ridged, and covered with inconspicuous down, the

leaflets are light bluish-green, thickish, nine to seventeen in number,

and the bracts are thin and dry. The flowers are about three-quarters

of an inch long, with a pinkish-green and downy calyx, and the corolla

all bright deep pink, fading to blue, with a veined standard. The

pod has from three to five divisions. This flourishes at rather high

altitudes, up to seven thousand feet, and is conspicuously beautiful

near the entrance to Ogden Canyon in Utah.

There are a great many kinds of Trifolium, or Clover, difficult to

distinguish; low herbs; leaves usually with three leaflets, usually

toothed; stipules adhering to the leaf-stalks; flowers in heads or

spikes; stamens usually in two sets of nine and one; pods small, mostly

enclosed in the calyx, usually with one to six seeds.

_Trifòlium tridentàtum_

=Purple

This is very common from the coast to the Sierra foothills, but there

are many named varieties. It is smooth all over and grows from eight

inches to two feet high, with spreading stems and narrow leaflets,

which are toothless, or have teeth and bristles on the edges. The

pinkish-purple flowers form a broad head, over an inch across, with an

involucre.

_Trifòlium fucàtum_

=Cream-color

Spring, summer

Wash., Oreg., Cal.=]

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.

=White

Spring, summer

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.
