Pedicularis dudleyi

Pedicularis dudleyi is a rare species of flowering plant in the family Orobanchaceae known by the common name Dudley's lousewort. It is endemic to central California, where it is known from about ten scattered occurrences along the coast and in the coastal mountain ranges. It has been found in three locations along the Central California coast. The species was named for 19th-century Stanford University botanist William Dudley.

Description

The species is a hairy perennial herb and produces one or more stems 10 to 30 centimetres (3.9 to 11.8 in) tall from a caudex. The leaves are up to 26 centimetres (10 in) long and divided into many toothed lobes or lobed leaflets. The inflorescence is a raceme of flowers occupying the top of the stem. Each flower is up to 2.4 centimetres (0.94 in) long and club-shaped, with a hood-like upper lip and a three-lobed lower lip. The flower is light pink or purplish with darker markings. At the base of the flowers are long-haired bracts and woolly sepals. The fruit is a capsule roughly 1 centimetre (0.39 in) long containing seeds with netted surfaces.

Locations

The plant thrives only among old-growth trees, depending on redwood leaf litter and on a complex array of fungi that grows on the roots of the trees. [1] Fewer than 10 known locations are known to support the plant in three areas along the Central California coast, including specific sections of Pescadero Creek in the Santa Cruz Mountains, the Arroyo De La Cruz In the South Santa Lucia Mountains, and one site within the boundary of Boy Scout Camp Pico Blanco. That location at the site of the former Catholic Chapel contains about 50% of the known specimens. [2] Monterey County cited the Scouts in 1989 for their "repeated destruction of Dudley's lousewort and its habitat." [1] When the council cut 38 damaged trees after a fire in 2003, wood cuttings were piled on top of the lousewort. [3]

Pedicularis furbishiae, or Furbish's lousewort, is a perennial herb found only on the shores of the upper Saint John River in Maine and New Brunswick. Furbish's lousewort was first recognized as a new species by Maine naturalist and botanical artist Kate Furbish in 1880. It is considered an endangered species in the United States and Canada, and is threatened by habitat destruction, as well as riverside development, forestry, littering and recreational use of the riverbank. It was formerly in the family Scrophulariaceae, but is now placed in the family Orobanchaceae. Once thought to be extinct, it is considered a Lazarus taxon.

<i>Euphorbia misera</i> Species of flowering plant

Euphorbia misera is a semi-succulent shrub in the genus Euphorbia commonly known as the cliff spurge or coast spurge. A drought-deciduous shrub, it is typically found as a gnarled, straggly plant occupying seashore bluffs, hills and deserts. Like other members of its genus, it has a milky sap, which can be found exuding out of the light gray bark when damaged. The alternately-arranged leaves are round and folded in the middle, with small hairs on them. The "flowers" can be found blooming year-round, and are colored maroon or yellow in the center with 5 white to light-yellow petal-like appendages attached outside. This species is native to the Baja California peninsula and Sonora in Mexico, and the coast of southern California in the United States, where it is a rare species. It is threatened in some localities by the development of its coastal habitat, which tends to be prime locations for high-end residential and commercial developments.

<span class="mw-page-title-main">Camp Pico Blanco</span>

Camp Pico Blanco is an inactive camp of 368 acres (149 ha) in the interior region of Big Sur in Central California. It is operated by the Silicon Valley Monterey Bay Council, of the Boy Scouts of America, a new council formed as a result of a merger between the former Santa Clara County Council and the Monterey Bay Area Council in December 2012. The camp is surrounded by the Los Padres National Forest, the Ventana Wilderness, undeveloped private land owned by Graniterock, and is located astride the pristine Little Sur River. The land was donated to the Boy Scouts by William Randolph Hearst in 1948 and the camp was opened in 1955. The camp was closed following the Soberanes Fire in 2017, and remained closed after Palo Colorado Road was severely damaged the following winter. Monterey County has been unable to budget the funds required to fix the road. In April 2022, the Silicon Valley Monterey Bay Council announced that the 18 acres (7.3 ha) camp and its buildings were for sale for $1.8 million, and also offered an adjacent 350 acres (140 ha) of undeveloped wilderness for $1.6 million.
