The crimson blossoms of the Poppy Mallow are abundant on prairies and plains at 3000-6000 ft. They bloom in early summer and midsummer and usually make deep masses of color among the grasses. Their beauty amply warrants introduction into home gardens. SPURGE FAMILY Snow-on-the-Mountain Euphorbia marginata Plate 7, fig. 4 The beauty of the Snow-on-the-Mountain is due to the white border of the leaves and bracts, and not at all to the flowers, which are reduced to tiny stamens and pistils. A field of these plants with their snowy foliage makes clear the reason for the common name. They may be found all summer in abundance in the clay soil of pastures and roadsides at 4000-7000 ft., but should be handled with care since the milky juice is poisonous. Where it touches the skin, it often causes itching and inflammation, accompanied with pimples and blisters very like those caused by poison ivy. This blistering action is so decided that the juice is said to be used to brand cattle in some parts of the West, as the scar heals more rapidly than one made by the branding iron. Honey made from the flowers is also poisonous, but since it is hot and disagreeable to the taste, it is not apt to be eaten. Snow-on-the-Mountain has considerable value as an ornamental plant for the garden, and it furnishes some rubber, though not in sufficient quantity to be commercially important. Other species of _Euphorbia_, or spurge, were formerly used as cathartics and stimulants, but they are all too acrid for safe application, either externally or internally. The small species are sometimes used to cauterize warts, but other means are more certain in their effect and less likely to cause injury to the surrounding skin. GERANIUM FAMILY Storksbill, Alfilaria Erodium cicutarium Plate 7, fig. 5 The fruit of the Storksbill bears a fancied resemblance to the long beak of a crane or stork, and both the common and scientific names refer to this resemblance. The flowers are rose-purple and look like those of a small geranium. The twisted fruits have been carried everywhere by sheep, and the plants are especially common in roadsides and pastures at 4000-7000 ft. The Storksbill has been somewhat used in medicine as a mild astringent and tonic, and under the name of “Filaree” it is greatly prized by stockmen as forage, especially for sheep.
