Lewisia disepala is a species of flowering plant in the family Montiaceae known by the common name Yosemite lewisia.
Lewisia disepala is a petite perennial herb growing from a thick branching taproot and short caudex unit. It produces a basal rosette of many small leaves no more than 1.5 centimeters long. The leaves are thick, fleshy, hairless, deep shiny green, and club-shaped, knobby, or finger-like, clumped tightly together. The inflorescence has a stem so short that the flowers sit directly on the basal rosette of leaves, or among them. Each flower has 5 to 8 pale to bright pink oval petals and 15 protruding stamens.
Lewisia disepala is endemic to the Sierra Nevada of California, where it is known from several sites high in the mountains. It grows in rocky mountain habitat such as talus and open beds of bare gravel.
Lewisia is a plant genus, named for the American explorer Meriwether Lewis (1774-1809) who encountered the species in 1806. The native habitat of Lewisia species is north facing cliffs in western North America. Local Native Americans ate the roots, which have also been used to treat sore throats.

Lewisia longipetala is a rare species of flowering plant in the family Montiaceae known by the common names long-petalled lewisia and Truckee lewisia. It is endemic to the Sierra Nevada of California, where it is known from less than 20 locations in areas not far from Lake Tahoe. It grows in subalpine and alpine climates in moist areas in rocky habitat, such as talus that retains patches of snow year-round. Most specimens grow on north-facing slopes with little surrounding vegetation. The plant thrives in the snow, growing largest and most densely in areas of high snowpack and becoming easily water-stressed when far away from areas with snow.
Lewisia nevadensis is a species of flowering plant in the family Montiaceae known by the common name Nevada lewisia. It is native to much of the western United States, where it grows in moist mountain habitat, such as meadows. This is a small perennial herb growing from a taproot and caudex unit. It produces a basal rosette of several narrow, fingerlike to threadlike fleshy leaves up to 13 centimeters long. The inflorescence is a bundle of short stems a few centimeters tall each bearing a flower. The flower has 5 to 10 shiny white to pale pink petals each 1 to 2 centimeters long, pointed or with blunt tips. At the center are many stamens. This is sometimes grown as an ornamental plant suitable for alpine and rock gardens.
Lewisia oppositifolia is a rare species of flowering plant in the family Montiaceae known by the common name opposite-leaf lewisia. It is native to the Klamath Mountains of Josephine County, Oregon, and Del Norte County, California, where it is a local serpentine endemic generally found in moist areas.

It is native to western North America from Alaska and Alberta to California and New Mexico, where it grows in many types of moist, rocky mountain habitat, such as gravel beds and sandy meadows. This is a highly variable species with a wide distribution, and it often hybridizes with other Lewisia species, making identification difficult. In general, this is a petite perennial herb growing from a taproot and caudex unit, and producing a basal rosette of several leaves 2 to 8 centimeters long. The leaves are narrow but thick and fleshy, blunt-tipped, and linear to lance-shaped. The inflorescence is usually made up of a few very short stems each bearing one or more flowers which appear to be sitting on or within the basal leaf rosette. Each flower has 5 to 9 white, pink or red petals which may or may not have dark veining or striping. The petals are 4 millimeters to 1 centimeter long.
Lewisia stebbinsii is a rare species of flowering plant in the family Montiaceae known by the common name Stebbins' lewisia.

The plant is known by the common names Tweedy's pussypaws, Tweedy's lewisia, or Tweedy's bitterroot. It is endemic to western North America in north-central Washington and adjacent British Columbia. It commonly grows on well-drained slopes often on rocky slopes or in rock crevices from low elevation ponderosa pine sites up to the drier part of the Grand Fir zone of the North Cascades. The flowers usually have a coral, apricot, or pink color.
Nepenthes chang is a tropical pitcher plant endemic to the Banthad Mountains of central Thailand, where it grows at elevations of 300–600 m above sea level. It is thought to be most closely related to N. kampotiana.
Primula suffrutescens is a species of primrose known by the common name Sierra primrose.
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.
Dudleya rubens is a species of succulent perennial plant in the family Crassulaceae known by the common name as the San Francisco liveforever, native to the mountains of Baja California Sur. It is a rosette-forming plant with waxy leaves, characterized by branching stems and dull red to apricot flowers. It is only found above 500 metres (1,600 ft) in the Sierra de San Francisco and the Sierra de la Giganta ranges in Baja California Sur, primarily on north-facing volcanic slopes.
