Cardamine corymbosa, commonly known as the New Zealand bitter-cress, [2] is a flowering plant in the family Brassicaceae. Native to the subantarctic islands of Australasia, it has become an invasive species in plant nurseries. The specific epithet refers to the structure of the inflorescence. [3]
New Zealand bittercress was described by Hooker as “a small and very distinct species of Cardamine, wiry and fragile in every part’’. [1] The plant has a low and spreading growth habit with unbranched stems which creep along the ground. It produces daughter plants through rooting at the nodes. The basal, compound leaves have three to five leaflets, with the terminal leaflet being up to twice as large as the lateral ones. [4]
The plant is native to New Zealand’s subantarctic Auckland and Campbell Islands, as well as to Australia’s Macquarie Island, where it occurs in alpine tundra and rocky coastal habitats. It has been accidentally introduced to other parts of the world, including North America and Europe, where it is a weed of nursery crops grown in polytunnels. [4]
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, some shrubs, with simple, although sometimes deeply incised, alternatingly set leaves without stipules or in leaf rosettes, with terminal inflorescences without bracts, containing flowers with four free sepals, four free alternating petals, two short and four longer free stamens, and a fruit with seeds in rows, divided by a thin wall.
Cardamine is a large genus of flowering plants in the mustard family, Brassicaceae, known as bittercresses and toothworts. It contains more than 200 species of annuals and perennials. Species in this genus can be found worldwide, except the Antarctic, in diverse habitats. The name Cardamine is derived from the Greek kardamon, cardamom, an unrelated plant in the ginger family, used as a pungent spice in cooking.

Megaherbs are a group of herbaceous perennial wildflowers growing in the New Zealand subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands.
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.
Cardamine flexuosa, commonly known as wavy bittercress or wood bitter-cress, is an herbaceous annual, biennial, or short-lived perennial plant in the cabbage family (Brassicaceae).

It is widespread and native to parts of Africa, and much of Asia, Europe and Eurasia, North America and the Caribbean. It can also be found in other parts of the world as an introduced species and a common weed, for example, in Australia and South America. It is an adaptable plant which grows in many types of damp, wet, and aquatic habitat. It may be an annual, biennial, or perennial plant, and is variable in appearance as well.

The Flora of Lord Auckland and Campbell's Islands is a description of the plants discovered in those islands during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1843 and 1845. Hooker sailed on HMS Erebus as assistant surgeon. It was the first in a series of four Floras in the Flora Antarctica, the others being the Flora of Fuegia, the Falklands, Kerguellen's land, etc (1845–1847), the Flora Novae-Zelandiae (1851–53), and the Flora Tasmaniae (1853–59). They were "splendidly" illustrated by Walter Hood Fitch.
