Montigena is a genus of flowering plant in the legume family Fabaceae, comprising a single species of dicotyledonous herb native to New Zealand, known as Montigena novae-zelandiae or more commonly the scree pea. 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.[3][4]
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.

Montigena es un género monotípico, pertenece a la familia Fabaceae, y consta de la sola especie M. novae-zelandiae, que hasta el año 1998, estuvo incluida en el género Swainsona, de donde se segregó. Este género es endémico de Nueva Zelanda de las pedrizas en las montañas secas del este de la Isla Sur.
El nombre Montigena, significa: "generado en la montaña", refiriéndose al hábitat donde se desarrolla.
El nombre común en inglés es "scree pea" ("guisante de la pedriza").
Sinónimos: Swainsona Salisb.
El Montigena tiene una diferente secuencia ITS de otras legumbres de Nueva Zelanda, pero forma un clado con el género australiano Swainsona (Wagstaff, 1999).
Según el análisis de las secuencias del ITS se estudia formar un clado que incluiría los género Carmichaelia, Clianthus, y Montigena de Nueva Zelanda, y el género Swainsona de Australia.
