Iris douglasiana (Douglas iris) is a common wildflower of the coastal regions of Northern and Central California and southern Oregon in the USA. The Douglas Iris was first described by 19th century botanist David Douglas in Monterey, California. It grows mainly at lower elevations, below 100 meters (330 ft), though it is occasionally found at heights of up to 1,000 meters (3,300 ft). It is most common in grasslands near the coast; it is regarded as a noxious weed in pastures, because it forms clumps that inhibit other vegetation, and its leaves are bitter and unpalatable to cattle.
Lonicera involucrata (Bearberry Honeysuckle, Bracted Honeysuckle, Twinberry Honeysuckle, Californian Honeysuckle, Twin-berry, Black Twinberry) is a species of honeysuckle native to northern and western North America, from southern Alaska east across boreal Canada to Quebec, and south through the western United States to California, and to Chihuahua in northwestern Mexico. It grows at elevations from sea level to 2,900 m.It is a large shrub that can grow 0.5–5 m high, with shoots with a quadrangular cross-section. The leaves are elliptic, to oval-shaped, 3–16 cm long and 2–8 cm broad; they are hairy along the margins and on the underside, and have a distinctive abruptly acuminate tip. The flowers are yellow, tubular, hairy, 1–2 cm long, and are monoecious; they are produced in pairs subtended by a pair of reddish basal bracts 2–4 cm across. The fruit is a 6–12 mm diameter black berry containing several small seeds.
Hesperomecon linearis (Bentham) Greene, Pittonia. 5: 146. 1903.
Platystigma lineare Bentham, Trans. Hort. Soc. London, ser. 2, 1: 407. 1834; Meconella linearis (Bentham) A. Nelson & J. F. Macbride; M. linearis var. pulchellum (Greene) Jepson; Platystemon linearis (Bentham) Curran
Plants 0.3-4 dm, sparsely pilose to densely hirsute. Leaves mostly basal, 0.5-8.5 cm; blade linear; margins entire. Inflorescences: peduncle 2.5-38 cm; bud globose to ovoid-cylindric. Flowers: petals white to cream colored, sometimes with yellow tips, sometimes tinged red in age, narrowly ovate to obovate, 0.3-2 × 0.2-1 cm, apex acute to obtuse; ovary ovoid-ellipsoid; stigmas deltoid, margins revolute. Capsules ovoid, to 1.5 cm. Seeds dark, shining, smooth. 2 n = 14.
Flowering early-late spring. Open, grassy areas in grasslands, sand dunes, oak and pine woodlands; 0-1000 m; Calif.
Depauperate plants of this species may be confused with Meconella , but Hesperomecon can be distinguished by its linear, pilose leaves and ovoid capsules. Robust plants may be confused with Platystemon , but the strictly 3-carpellate, strongly syncarpous gynoecium and valvate capsules of Hesperomecon are always diagnostic.
Epilobium ciliatum is a species of Epilobium known by the common names Fringed Willowherb, Slender Willow herb, and Northern Willow herb. This plant is native to much of North America, southern South America, and East Asia. It is an introduced species in much of Eurasia and Australia.
This perennial herbaceous plant usually occurs in wetlands, but may be found in a great variety of habitats, including disturbed areas and roadsides, at elevations below 1,400 metres (4,600 ft).
