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.
