Brodiaea pallida is a rare species of flowering plant in the cluster-lily genus known by the common name Chinese Camp brodiaea.
Brodiaea pallida is endemic to California, where it is known from a two populations along the border between Tuolumne and Calaveras Counties. [4]
The first population is at the type locality near Chinese Camp and contains a varying number of individuals which has been estimated at 600 to 5000. [4] This population is limited to a 65-acre (26 ha) tract of land which is privately owned. [3] The plant was federally listed as a threatened species in 1998. [3] In the year 2000, a second population was discovered 24 kilometres (15 mi) away, and it may contain up to 10,000 individuals. [4] The species is threatened by development of its habitat. [1]
Brodiaea pallida is a perennial producing an inflorescence up to about 20 centimetres (7.9 in) tall bearing pale purple flowers on short pedicels. Each flower has six strongly curving tepals about a centimeter long. In the center of the flower are three erect white, notch-tipped sterile stamens called staminodes, each about as long as the tepals. Within these are the fertile stamens. Flowering occurs in late May and early June. [1]
This plant grows in mixed soils of volcanic and serpentine origin [4] in vernally moist areas of grassland next to intermittent streams. At the time it was placed on the endangered species list, it was known only from a strip of land under 0.8 kilometres (0.50 mi) long and just 6 metres (20 ft) wide, and was at risk for extinction from any one destructive event. [3] The population had been fragmented and part was destroyed by construction activity in 1982. [4] [3] It was listed as a threatened species rather than an endangered species because no further disturbance was planned for the area at the time. [3] The second population is also located on privately owned land. [4] It is on the outskirts of the town of Copperopolis, and it is in a zone slated for residential construction. [4] Even if development does not occur at the locations of the plants, development activity nearby could still affect them by altering the flow of the streams, increasing runoff, or encouraging development of roads and firebreaks. [4]
The genetic variability of the populations is unknown because it reproduces vegetatively by cloning as well as sexually by seed. [4]
Brodiaea, also known by the common name cluster-lilies, is a monocot genus of flowering plants.
Platanthera yadonii, also known as Yadon's piperia or Yadon's rein orchid, is an endangered orchid endemic to a narrow range of coastal habitat in northern Monterey County, California. In 1998 this plant was designated as an endangered species by the United States government, the major threat to its survival being continuing land development from an expanding human population and associated habitat loss. One of the habitats of Yadon's piperia, the Del Monte Forest near Monterey, California, is the subject of a federal lawsuit, based upon endangerment of this organism along with several other endangered species.
Cirsium pitcheri, sometimes called Pitcher's thistle or dune thistle, is a species of thistle native to sand dune shorelines along the upper Great Lakes. It is native to Indiana, Illinois, Michigan, Wisconsin, and Ontario. It is listed by the U.S. Fish and Wildlife Service as a threatened species.
Verbena californica is a rare species of verbena known by the common names California vervain and Red Hills vervain. This flower is endemic to Tuolumne County, California, where it is known from ten or eleven occurrences in the Red Hills, a section of the Sierra Nevada foothills near Chinese Camp. It grows in moist woodland habitat, often on serpentine soils. It is a federally listed threatened species of the United States.
Hooveria purpurea is a species of flowering plant related to the agaves known by the common name purple amole. This species of soap plant is endemic to California, where it grows in the Santa Lucia Range, in the Central Coast region. There are two varieties of this plant, and both are believed to be quite rare. It is a federally listed threatened species.
Fritillaria gentneri, or Gentner's fritillary, is a rare species of flowering plant in the lily family Liliaceae, that is endemic to southwest Oregon and adjacent Siskiyou County, California, USA. Its habitat is dry, open woodlands and chaparral at 1,000–5,000 ft (300–1,520 m), where it blooms from March through July. However, most populations have generally finished blooming by the end of May. As with many plants, the lower elevations bloom earliest with the bloom period moving up following elevation.
Erythronium pluriflorum is a rare species of flowering plant in the lily family Liliaceae which is known by the common names manyflower fawn lily,golden fawn-lily, and Shuteye Peak fawn lily.
Arctostaphylos pallida, commonly known as pallid manzanita, Oakland Hills manzanita, and Alameda manzanita, is an upright manzanita shrub from the Ericaceae, or heath family. It is endemic to the eastern San Francisco Bay Area of Northern California.
Eremogone ursina is a species of flowering plant in the family Caryophyllaceae known by the common name Bear Valley sandwort.
Brodiaea elegans is a species of flowering plant in the cluster-lily genus known by the common names harvest brodiaea, elegant brodiaea, and elegant cluster-lily.
Brodiaea filifolia, known by the common name threadleaf brodiaea, is a rare species of flowering plant in the cluster-lily genus. It is endemic to southern California, mostly in the region around the junction of Orange, Riverside, and San Diego Counties.
Brodiaea insignis is a rare species of flowering plant in the cluster-lily genus known by the common name Kaweah brodiaea. It is endemic to the Sierra Nevada foothills of central Tulare County, California, where it grows along the Tule and Kaweah Rivers. It is considered endangered on the state level.
Brodiaea jolonensis, known by the common name chaparral brodiaea, is a species of flowering plant in the cluster-lily family.
Brodiaea minor is a species of flowering plant in the cluster-lily genus known by the common names dwarf brodiaea and vernalpool brodiaea.
Brodiaea stellaris is a species of flowering plant in the cluster-lily genus known by the common name starflower brodiaea.
Calyptridium pulchellum, synonym Cistanthe pulchella, is a rare species of flowering plant in the family Montiaceae. It is known by the common name Mariposa pussypaws. It is endemic to the Sierra Nevada foothills of central California, where it is known from only a few scattered occurrences. It grows on barren patches of granite gravel in woodland and grasslands. It is a federally listed threatened species.
Clarkia springvillensis is a rare species of flowering plant in the evening primrose family known by the common name Springville clarkia. It is endemic to central Tulare County, California, where it is known from fewer than 20 occurrences around Springville. It is a federally listed threatened species.
Brodiaea santarosae is a rare Brodiaea species known by the common name Santa Rosa brodiaea and Santa Rosa Basalt brodiaea. It is endemic to southern California, mostly in the region around the junction of Orange, Riverside, and San Diego Counties and limited to ancient basaltic soils. There are only five known populations. It was once thought to be an intergrade of Brodiaea filifolia and B. orcuttii, but measurements found this to be false. It was described as a new species in 2007.
