This is the only kind of Eulobus. It would be a pretty plant, if more flowers were out at one time and if they did not close so soon. The smooth, hollow, loosely-branching stem is from one to three feet tall, with a "bloom," the leaves are smooth, rather light dull-green, and the buds are erect. The flowers are about three-quarters of an inch across, with a very short calyx-tube, light-yellow petals, fading to reddish-pink, eight stamens, four of them smaller and shorter, and the light-green stigma with a round top. The slender pods are three inches long, smooth, cylindrical, and turning stiffly down, with many seeds. This grows in mountain canyons.
Eulobus Californicus. EVENING PRIMROSE FAMILY. Onagraceae.
There are a few kinds of Chamaenerion; perennials, often woody at base; leaves alternate; flowers in clusters, perfect, slightly irregular, white or purplish; petals four; stamens eight; style threadlike, with a four-cleft stigma; capsule long, four-sided, containing numerous seeds, tipped with a tuft of hairs. The calyx-tube is not prolonged beyond the ovary, which chiefly distinguishes this genus from Epilobium.
