Brassicaceae Family of flowering plants

Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. They have simple alternatingly-set leaves, without stipules, or in leaf rosettes. Their inflorescences are terminal and bractless. Their flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. Their fruit has seeds in rows, divided by a thin wall.

<i>Anemone occidentalis</i> Species of flowering plant

Anemone occidentalis, the white pasqueflower or western pasqueflower, is a herbaceous species of flowering plant in the buttercup family Ranunculaceae. Other authorities place it in the genus Pulsatilla. Individuals are 10–60 cm (3.9–23.6 in) tall, from caudices, with three to six leaves at the base of the plant that are 3-foliolate, each leaflet pinnatifid to dissected in shape. Leaf petioles are 6–10 cm (2.4–3.9 in) long. Leaves have villous hairs and their margins are pinnatifid or dissected. Plants flower briefly mid-spring to mid-summer, usually soon after the ground is exposed by melting snow. The flowers are composed of five to seven sepals, normally white or soft purple, also mixed white and blueish purple, one flower per stem. The sepals are 15–30 mm (0.59–1.18 in) long and 10–17 mm (0.39–0.67 in) wide. Flowers have 150–200 stamens. The fruit occurs in heads rounded to subcylindric in shape, with pedicels 15–20 cm (5.9–7.9 in) long. The achenes are ellipsoid in shape, not winged, covered with villous hairs, with beaks curved that reflex as they age and 20–40 mm (0.79–1.57 in) long, feather-like. Generally, the fruit persists into fall.

<i>Cardamine impatiens</i> Species of flowering plant

Cardamine impatiens, the narrowleaf bittercress or narrow-leaved bitter-cress, is a plant species in the genus Cardamine of the family Brassicaceae. It is a slender, biennial herb, that produces sterile leaves in the first year, one to several flowering stems during the next. Its leaves are pinnate with several pairs of lanceolate, dentate leaflets and a terminal, slightly longer leaflet. The short petals surpass the calyx by half of its length. The seeds are arranged in one row on each side of the central membrane of the narrow pod and are ejected out in a shower due to the tension formed as the seed pod (silique) dries. It grows on walls, open ground in shady places in forests usually disturbed by man.

The wispy leaves grow from the base of the stem and may approach half the stem's length. The inflorescence holds loose bundles of individual flowers and there is usually one long, leaflike bract extending far past the flowers. Each flower has green-striped brownish to reddish tepals each several millimeters long, and six stamens with small anthers. The fruit is a brown capsule which grows encased within the tepals.
