Capsella Bursa-pastoris, Medic. Mustard Family.

Among our commonest and most harmless weeds is the shepherd's purse, which has been introduced from Europe in the past. It may be easily recognized by its tiny white cruciferous flowers and its shapely little triangular, flat pods, which have a peppery taste. It is used medicinally, and valued as a remedy for many different maladies. In Europe, a common name for the plant is "mother's heart," and Mr. Johnston says that children play a sort of game with the seed-pouch. "They hold it out to their companions, inviting them to 'take a haud o' that.' It immediately cracks, and then follows a triumphant shout, 'You've broken your mother's heart!'"

Equally common is the Lepidium, or pepper-grass, the small round, flat pods of which also have a peppery taste. Both of these belong to the great Mustard family.

Hab.—Dry sandy soil, in the Coast Ranges and Sierra foothills, from Mendocino County to Los Angeles.

I once emerged from the dense chaparral of a steep hillside upon a grassy slope, where myriads of these lovely flowers tossed their delicate cups upon the breeze. As I passed from flower to flower, I noticed many insect guests regaling themselves upon the nectar. Bees and flies jostled one another and crawled amid the hairs below, and beautifully mottled butterflies hovered over them.

[MARIPOSA TULIP—Calochortus venustus.]

As originally described, this flower was white or pale lilac, with a more or less conspicuous, usually reddish, stain, or blotch, near the top, a brownish spot bordered with yellow in the center, and a brownish striate base. But it varies so widely from this type, in both color and spots, that neither is a reliable character from which to determine the species. Some of the oculated forms of C. luteus are so similar that they are readily confused with this, but a careful examination of the gland and the form of the capsule, together with the character of the soil in which the plants grow, will identify the species.
