Epilobium obcordatum is a species of perennial plant in the evening-primrose family (Onagraceae), known by the common name rockfringe willowherb[ citation needed ] and rock fringe. [1] It is native to the western United States from California to Idaho, where it is found in rocky mountainous areas, at altitudes of 7,000 ft (2,100 m) to 13,000 ft (4,000 m). [2] This small perennial is clumpy to mat-forming and spreads from a woody caudex, especially in nooks between rocks. It has stems lined with oval or rounded leaves which spread parallel to the ground or ascend somewhat. At the tips of the thin stems are flowers each with four petals. The petals are magenta to purple, rounded and notched, often in a perfect heart shape, and are one or two centimeters long. The glandular, club-like, ridged fruit is a capsule two to four centimeters long growing on a short stalk.

This is a perennial herb growing from a short, thick taproot and caudex unit. It produces a basal rosette of thick, fleshy, blunt-tipped spoon-shaped leaves with serrated edges. The inflorescence is a very slender erect stem up to 45 centimeters tall topped with a spreading panicle of flowers and glandular, toothed bracts.

It grows in many types of open habitat. It is a rhizomatous perennial herb growing erect or leaning with a tall naked flowering stem. The leaves are located on the lower part of the stem, each divided into rounded lobes. The stem bears up to 25 flowers, each in a cuplike calyx of red or green sepals. The five petals are white, under one centimeter long, and toothed or smooth along the edges.
Oenothera xylocarpa is a species of flowering plant in the evening primrose family known by the common name woodyfruit evening primrose. It is native to the Sierra Nevada of California, its range extending just into western Nevada. It grows in coniferous forest and meadow habitat, often in soils rich in pumice and other gravel. It is a perennial herb growing from a thick taproot and producing a flat, dense rosette of hairy, gray-green leaves. There is no stem. The showy flowers appear amidst the leaves. Each has four petals which may be nearly 4 centimeters long, bright yellow in color, fading pink to red with age. The fruit is a straight, curving, or twisting capsule which may be up to 9 centimeters long.

The flora of the U.S. Sierra Nevada alpine zone is characterized by small, low growing, cushion and mat forming plants that can survive the harsh conditions in the high-altitude alpine zone above the timber line. These flora often occur in alpine fell-fields. The Sierra Nevada alpine zone lacks a dominant plant species that characterizes it, so may or may not be called a vegetation type. But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations.
