Swainsona novae-zelandiaeHook.f. (1864)

Montigena is a genus of flowering plant in the legume family Fabaceae. It includes the sole species Montigena novae-zelandiae, known more commonly the scree pea, a dicotyledonous herb endemic to the South Island of New Zealand. The plant is small and woody, arising from thin, branched stems that extend to the surface from a deeply buried root stock. The flowers vary from purple to brown, while fruits appear between January and April. [2]

M. novae-zelandiae was previously classified as Swainsona novae-zelandiae until 1998 when the genus Montigena was created based on the morphological features of the plant. [4] [5]

Under the New Zealand Threat Classification System, it is classified as "At Risk - Declining". Its decline is predicted to be from 10% to 50% from a population of from 20,000 to 100,000 mature plants. Further comments are that it is sparse and that there are recruitment failures. [1]

Montigena is one of the four genera of native legumes in New Zealand; the other three are Carmichaelia, Clianthus , and Sophora .

<i>Sophora</i> Genus of plants

Sophora is a genus of about 45 species of small trees and shrubs in the pea family Fabaceae. The species have a pantropical distribution. The generic name is derived from sophera, an Arabic name for a pea-flowered tree.

<i>Carmichaelia</i> Genus of legumes

Carmichaelia is a genus of 24 plant species belonging to Fabaceae, the legume family. All but one species are native to New Zealand; the exception, Carmichaelia exsul, is native to Lord Howe Island and presumably dispersed there from New Zealand.

<i>Clianthus</i> Genus of legumes

Clianthus, commonly known as kakabeak, is a genus of flowering plants in the legume family Fabaceae, comprising two species of shrubs endemic to the North Island of New Zealand. They have striking clusters of red flowers which resemble the beak of the kaka, a New Zealand parrot. The plants are also known as parrot's beak, parrot's bill and lobster claw – all references to the distinctive flowers. There is also a variety with white to creamy coloured flowers called: "Albus," and a variety with rosy pink flowers called: "Roseus."

Clianthus puniceus, common name kaka beak, is a species of flowering plant in the genus Clianthus of the legume family Fabaceae, native to New Zealand's North Island.

<i>Carmichaelia carmichaeliae</i> Species of legume

Carmichaelia carmichaeliae is a species of plant in the family Fabaceae. It is found only in South Island of New Zealand. It is classified as having the "Nationally Critical" conservation status under the New Zealand Threat Classification System.

<span class="mw-page-title-main">Galegeae</span> Tribe of leguminous plants

Galegeae is a tribe in the flowering plant family Fabaceae, subfamily Faboideae. The tribe is found mostly in the northern hemisphere, but can also be found in Australia, Africa, and South America. Recent molecular phylogenetic work has determined that tribe Galegeae is paraphyletic, and that its members are scattered throughout the IR-lacking clade.

Sophora cassioides is a legume tree native to Chile.

<i>Donatia novae-zelandiae</i> Species of flowering plant

Donatia novae-zelandiae is a species of mat-forming cushion plant, found only in New Zealand and Tasmania. Common names can include New Zealand Cushion or Snow Cushion, however Snow Cushion also refers to Iberis sempervirens. Donatia novae-zelandiae forms dense spirals of thick, leathery leaves, creating a hardy plant that typically exists in alpine and subalpine bioclimatic zones.

<i>Pleurophyllum speciosum</i> Species of plant

Pleurophyllum speciosum, also known as the giant emperor daisy or Campbell Island daisy, is a megaherb native to the Auckland and Campbell Islands of New Zealand. A false colour image is depicted on the lower left corner on the reverse of the current five dollar New Zealand banknote. The Campbell Island daisy was first described by Joseph Dalton Hooker in Flora Antarctica of 1844, after he had collected it during the Ross expedition.

<i>Sporadanthus ferrugineus</i> Species of flowering plant

Sporadanthus ferrugineus, the bamboo rush or giant wire rush, is a restiad plant endemic to the northern North Island of New Zealand.

Aceria clianthi is a species of mite belonging to the family Eriophyidae. It is found only in New Zealand. It is notable for being host specific to threatened plants of the genus Clianthus. It is classified by Buckley et al. as "nationally critical" under the New Zealand Threat Classification System. They stated "Aceria clianthi (Eriophyidae), has been recorded only from kakabeak in cultivation and once on Lotus cornalatus [Lotus corniculatus] (Fabaceae), an introduced plant growing near kakabeak. It is given the same threat classification as kakabeak ." Heenan had earlier stated that "the two species [of Clianthus] are considered to be threatened, with C. maximus having a rank of vulnerable, whereas C. puniceus is critically endangered", but the conservation status of C. maximus was subsequently found to be more serious. These threat classifications for Clianthus apply to plants in the wild, but the species are widely cultivated. Aceria clianthi occurs on both plants in the wild and in cultivation.

Dracophyllum menziesii, commonly known as pineapple scrub, is a species of shrub endemic to the South and Stewart Islands of New Zealand. In the heath family Ericaceae, it inhabits mountain slopes and cliffs from sea level up to 1,500 m (4,921 ft) and reaches a height of 0.5–1 m (1.6–3.3 ft). A 2017 assessment using the New Zealand Threat Classification System classified it as "Not Threatened," giving it an estimated population upwards of 100,000.
