Platanthera cooperi is an uncommon species of orchid known by the common names Cooper's rein orchid and chaparral rein orchid.
The orchid is endemic to chaparral, coastal sage scrub, and oak woodland habitats. It is native to southern California and the border area in Baja California.
It is found in the Santa Monica Mountains, Simi Hills, and San Gabriel Mountains of the Transverse Ranges; Santa Catalina Island and San Clemente Island of the Channel Islands, and the Santa Ana Mountains and Cuyamaca Mountains of the Peninsular Ranges. [1]
Platanthera cooperi grows erect to about 90 centimetres (35 in) in maximum height from a bulbous caudex. The basal leaves are up to 20 centimeters long by 3 cm wide. Leaves higher on the stem are much reduced.
The upper part of the stem is a spikelike inflorescence of many small green flowers, which are honey-scented in the evenings. Its bloom period is from March to June.
This orchid is a listed vulnerable species on the California Native Plant Society Inventory of Rare and Endangered Plants. [2]
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.
Piperia is a former genus within the orchid family Orchidaceae that has since been subsumed under Platanthera.
Platanthera elegans is a species of orchid known by several common names, including elegant piperia, coast piperia, hillside rein orchid, and hillside bogorchid. This is a showy flowering plant native to western North America. It grows from a caudex tuber and sends up a thick stem just under a meter in maximum height. The stem is topped with a cylindrical spike inflorescence of densely packed flowers with curving white to greenish-yellow petals. Coastal individuals are noticeably thicker and have more flowers than those that grow further inland; it is uncertain if these are variants, subspecies, or even separate species. They are both currently treated as P. elegans. Other species of Plantanthera, notably the endangered species P. yadonii are quite similar in appearance to some populations of this species.

Eryngium aristulatum, known by the common names California eryngo and Jepson's button celery, is a species of flowering plant in the family Apiaceae.

Platanthera ephemerantha is a species of orchid known by the common names whiteflower rein orchid, slender white piperia, and white-flowered piperia. It is native to western North America from Alaska to the San Francisco Bay Area, where it grows in coniferous forests and other habitat in coastal and inland mountain ranges within 150 kilometers of the coast. It grows erect to about half a meter in maximum height from a bulbous caudex. The basal leaves are up to 18 centimeters long by 3 wide. Leaves higher on the stem are much reduced. The upper part of the stem is a spikelike inflorescence of up to 100 small flowers, mostly arranged along one side of the stem. The fragrant, honey-scented flowers are whiter than those of other Platanthera, but sometimes green-tinged or -veined, or green with white margins. The status of this species in the wild is difficult to determine because most populations are small and may produce flowers only rarely.
Platanthera colemanii is a rare species of orchid known by the common names Coleman's piperia and Coleman's rein orchid. It is endemic to California, where it is known from scattered occurrences along the Sierra Nevada and one disjunct location in Colusa County, California. It grows in coniferous forests and chaparral in deep sandy substrates. It was differentiated from the very similar Platanthera unalascensis in 1993.
Platanthera michaelii is an uncommon species of orchid known by the common names Michael's rein orchid and Michael's piperia. It is endemic to California, where it is known from the coastal plains, hills, and mountains, and the Sierra Nevada foothills. It can be found in varied habitat, including scrub, woodland, and forest. This orchid grows erect to about 70 centimeters in maximum height from a bulbous caudex. The basal leaves are up to 24 centimeters long by 5 wide. Leaves higher on the stem are much reduced. The upper part of the stem is a spikelike inflorescence of many yellow-green flowers which are fragrant in the evenings.
Platanthera transversa is a species of orchid known by the common names royal rein orchid and flat spurred piperia.
Clinopodium chandleri is an uncommon species of flowering plant in the mint family known by the common name San Miguel savory. It is native to northern Baja California and several areas of southern California, where it can be found in mountain chaparral. A fragrant plant with white flowers, it is one of southern California's rarest shrubs.
