Endosamara is a monotypic genus of flowering plants in the legume family Fabaceae,[1] tribe Wisterieae.

The inner surface is pink or pinkish purple, rarely white, with a dark greenish yellow nectar guide.

A unique feature of the genus Endosamara within the tribe Wisterieae is that the pods split into one-seeded segments before releasing the seeds.

[2] It was later placed in a number of other genera, including Millettia and Wisteria, before in 1984 Robert Geesink established the new genus Endosamara for the species, based principally on the unique structure of the seeds, which have flat samara-like wings but are enclosed in endocarp.

[3] Endosamara is placed in the tribe Wisterieae, where it forms the earliest diverging clade with the genera Sarcodum and Sigmoidala.
