Erysimum insulare is a species of Erysimum known by the common name island wallflower. It is endemic to coast of southern California, including the Channel Islands. Erysimum insulare grows on coastal bluffs and sand dunes. [1]
Erysimum insulare is a perennial herb or subshrub producing a branching, erect stem 5 to 60 centimeters tall. It is lined with many hairy leaves which are linear to widely lance-shaped. The longest leaves near the base of the stem may be up to 15 centimeters long.
The top of the stem is occupied by a raceme inflorescence of many bright yellow to yellow-orange flowers. The fruit is a silique up to 10 centimeters long.
There are two subspecies of this plant:
Coastal strand is a plant community of flowering plants that form along the shore in loose sand just above the high tide line.
Erysimum nevadense is a perennial short-lived herb endemic to the Sierra Nevada of Spain, although there are some citations in the nearby Sierra de Gádor (Almería). This wallflower occurs between 1,700 and 2,700 m above sea level in subalpine scrublands and alpine meadows. It may be treated as a narrowly circumscribed single species, one of a group or complex of six separate species, or as a more broadly circumscribed species with six subspecies.
Arctostaphylos tomentosa is a species of manzanita known by the common name woollyleaf manzanita or woolley manzanita. This shrub is endemic to California.
Triteleia ixioides, known as prettyface or golden star, is a monocotyledon flowering plant in the genus Triteleia. It is native to northern and central California and southwestern Oregon, where it can be found in coastal and inland coniferous forests and other habitat. It is a perennial wildflower growing from a corm. It produces one to two basal leaves up to 50 centimeters long by 1.5 wide. The inflorescence arises on an erect stem up to 80 centimeters tall. It is an umbel-like cluster of several flowers each borne on a pedicel up to 7 centimeters long. The flowers are variable in size, measuring one to nearly three centimeters in length. They are pale to bright yellow, or sometimes purple-tinged white. There are six tepals with darker midveins in shades of green, brown, or purple. The lobes are funnel-shaped and may open flat or somewhat reflexed. The six stamens form a fused tube that protrudes from the corolla; they have broad, flat filaments and whitish, yellowish, or blue anthers.
Cordylanthus tenuis is a species of flowering plant in the family Orobanchaceae known by the common name slender bird's beak. It is native to the US states of California, Oregon, and Nevada, where it grows in woodland and forest. It erects a spindly stem which may exceed a meter in height with sparse narrow leaves a few centimeters long, and is sometimes sticky with glandular secretions. The plant is greenish and tinted with yellow or purple coloration. The stem branches at intervals and at the end of each branch is a cluster of one to several flowers. Each pocket-shaped flower is one to two centimeters long and about one wide, made up of fuzzy maroon lobes with white or yellow lips.
Dudleya abramsiisubsp.calcicola is a succulent plant known by the common name limestone liveforever, or limestone dudleya. It is endemic to California, where it is a rare resident of limestone outcroppings and rocky slopes in the southern Sierra Nevada and nearby mountains and foothills. It was formerly regarded as Dudleya calcicola.
