Lewisia congdonii, known by the common name Congdon's lewisia, is a rare species of flowering plant in the family Montiaceae.
Lewisia congdonii is a perennial herb growing from a short, thick taproot and caudex unit. It produces a basal rosette of several thick, fleshy leaves with lance-shaped blades tapering down to a long petiole. The inflorescence arises on one or more stems 20 to 60 centimeters tall, each stem bearing an array of up to 100 flowers each. Near the flowers are small, pointed bracts tipped with resin glands. The flower has 6 or 7 petals, each up to about a centimeter in length and lance-shaped with a toothed tip. The petals are pale pink with sharp dark pink veining. The throat is sometimes tinged with greenish yellow.
Lewisia congdonii is endemic to the Sierra Nevada of California, where it is known from only ten occurrences in the drainage canyons of the Kings and Merced Rivers. [1]
Clarkia franciscana is a rare species of flowering plant in the evening primrose family known by the common name Presidio clarkia. It is endemic to the San Francisco Bay Area of California, where it is known only from two populations at the Presidio of San Francisco and three occurrences in Oakland. The plant is known only from serpentine soils.
Lewisia brachycalyx is a species of flowering plant in the family Montiaceae, known by the common name short-sepal bitter-root or shortsepal lewisia. It is native to the mountains of the southwestern United States and Baja California, where it grows in moist habitat such as meadows. It is a deciduous perennial growing from a short thick taproot and caudex unit. It produces a basal rosette of thick, fleshy, blunt-tipped narrow leaves up to 8 centimeters long. The inflorescence is under 4 centimeters tall, taking the form of a cluster of several flowers sitting atop the leaf rosette. Each flower has 5 to 9 shiny white or pink petals about 2 centimeters long. At the center are many stamens and stigmas clumped together. The Latin specific epithet brachycalyx means “having a short calyx”.
Lewisia cantelovii is an uncommon species of flowering plant in the family Montiaceae known by the common name Cantelow's lewisia.

Streptanthus glandulosus is a species of flowering plant in the mustard family known by the common name bristly jewelflower. It is native to California and southwestern Oregon, where it grows in many types of habitat, including grassland, chaparral, and woodlands. Genetic and other analyses indicate that it is a species complex with ten subspecies which evolved as populations were isolated from each other. The complex includes subspecies previously considered separate species, such as the rare Tiburon jewelflower endemic to the San Francisco Bay Area. Plants in the complex are variable. In general they are annual herbs growing 10 centimeters to over a meter in height. They may be hairless to hairy to bristly. The ephemeral basal leaves have blades borne on winged petioles. Leaves higher on the stem are linear to lance-shaped and clasp the stem at their bases. Flowers occur at intervals along the upper stem. Each flower has an urn-shaped calyx of sepals one half to over one centimeter long which can be most any color from white to yellowish to pink or purple to nearly black. Purple, white, or purple-veined white petals emerge from the tip. The fruit is a straight or curving silique up to 11 centimeters long.
Streptanthus vernalis is a rare species of flowering plant in the mustard family known by the common name early jewelflower. It was first observed in the 1970s but not actually described to science until 2005. It is endemic to Lake County, California, where it is known from a single occurrence at Three Peaks near the Napa County line. It is apparently limited to serpentine outcrops in forested and chaparral habitat. Genetic analysis indicates that the species is distinct from other Streptanthus and is most closely related to Streptanthus morrisonii, which it resembles. It is a hairless annual herb producing an erect branching or unbranched stem 2 to 20 centimeters tall. The ephemeral basal leaves have thick, fleshy leaves which are green and unmottled on top and purple on the undersides. Leaves higher on the stem are linear to lance-shaped and lack petioles. Flowers occur at intervals along the upper stem. Each flower has an urn-shaped calyx of sepals which is solid green with no purple or yellowish tinge. The petals emerging from the tip are white without darker veining. The fruit is a flattened straight silique 3 to 5 centimeters long containing orange seeds.
