Camassia howellii, commonly known as Howell's camas, is a species of perennial flowering plant in the family Asparagaceae endemic to western Oregon. [2]
Discovered in 1889, Camassia howellii is now considered to be imperiled due to residential development, mining and grazing. [3]
Camassia howellii is found exclusively in the southwestern region of Oregon, almost only in Josephine county, including on Grants Pass and Sexton Mountain. [4] The 12 populations make up a total of 3000 plants. These sites are threatened by human developments. This species is currently under the global conservation status rank G2 Imperiled. [5] Although other species of Camassia are still abundant in the Northwest, this one is not in Oregon.
Camassia howellii thrives in wet meadows in serpentine soil. They are found in eastern Oregon where precipitation levels range from 70 to 100 inches per year and temperatures from 40 to 80 degrees Fahrenheit per year. These perennials are late bloomers usually during the month of May and the flowers will wither in the autumn. [6] The common elevation is between 200 and 700 meters high. [4]
Camassia howellii grows from a bulb and has 60 cm long basal leaves which range around 4 to 7 per plant.
The plant's inflorescences reach about 15 to 40 cm (6 to 15.5 in) long which are usually bluish violet. The flowers are actinomorphic made up of five 20 mm (0.79 in) long petals. There can be 100 flowers in a raceme. These flowers sit atop a stem about 50 cm (19.5 in) tall. [3] The flowers are radially symmetrical and are composed of five deep bluish violet petals. The petals range from 10 to 20 mm long and about 3 to 5 mm wide. [7] This species is known to bloom in the month of May. The small bulbs are between 1.5 and 3 centimeters in diameter, and have a brown coat. The few, narrow leaves are between 20 and 60 centimeters in length. The capsule fruit is between 0.5 and 1 centimeter in long, shiny green in color, and has 2 to 5 seeds per fruit. It has smaller capsules and wider spreading pedicels compared to other Camassia species. [4]
Native Americans and settlers considered Camassia howellii as an important part of their diet. The city of Camas in Washington and many parts of the Northwestern United States was named after this plant due to its large cultivation and consumption by the Native Americans and first white settlers.
In autumn the bulbs were harvested after the flowers dried up and were boiled or pit-cooked. [8] The bulbs were also dried and ground into flour. As the settlers began to expand their territory, they raised cattle which limited the growth of camas in the area.
The common names soap plant, soaproot and amole refer to the genus Chlorogalum. They are native to western North America, with some species in Oregon but they are mostly found in California. Common names of the genus and several species derive from their use as soap.
Chlorogalum pomeridianum, the wavy-leafed soap plant, California soaproot, or Amole, is the most common and most widely distributed of the soap plants, soaproots or amoles, which make up the genus Chlorogalum of flowering plants. It is occasionally known as the "wild potato", but given the plant's lack of either resemblance or relationship to the potato, this name is not recommended.
Camassia is a genus of plants in the asparagus family native to North America. Common names include camas, quamash, Indian hyacinth, camash, and wild hyacinth.

Erythronium americanum, the trout lily, yellow trout lily, or yellow dogtooth violet, is a species of perennial, colony forming, spring ephemeral flower native to North America and dwelling in woodland habitats. Within its range it is a very common and widespread species, especially in eastern North America. The common name "trout lily" refers to the appearance of its gray-green leaves mottled with brown or gray, which allegedly resemble the coloring of brook trout.
Camassia scilloides is a perennial herb known commonly as Atlantic camas, wild hyacinth, and eastern camas. It is native to the eastern half of North America, including Ontario and the eastern United States.

It is native to northern California and southern Oregon, where it grows in the forest and woodlands of the mountains. It is a perennial herb which produces a branching stem up to about 30 centimeters in maximum height. There is a basal leaf about 20 centimeters long which does not wither at flowering. The inflorescence bears 1 to 5 erect bell-shaped flowers. Each flower has three sepals and three light purple petals with darker areas at the bases. The petals are 3 to 4 centimeters long and have a coat of long hairs on their inner surfaces. The fruit is a winged capsule about 2 centimeters long.

Pedicularis howellii is an uncommon species of flowering plant in the family Orobanchaceae known by the common name Howell's lousewort. It is endemic to the Siskiyou Mountains of the Klamath Range in southern Oregon and northern California, where it grows on the edges of coniferous forests. This is a perennial herb producing one or more stems up to 45 centimetres (18 in) tall from a long caudex. The leaves are up to 20 centimetres (8 in) long, lance-shaped, and divided into many toothed oval lobes; those higher on the stem may be unlobed. The basal leaves fall away early. The inflorescence is a small raceme of flowers occupying the top of the stem. Each white to light purple flower is up to one centimetre long and is sickle-shaped, with a curved beak-like upper lip and a three-lobed lower lip which may be tucked into the hairy mass of sepals. The plant is pollinated by bumblebees including Bombus mixtus. Between the flowers are hairy to woolly triangular bracts. The fruit is a capsule just under a centimeter long containing seeds with netted surfaces.
