Rhinotropis heterorhyncha, synonym Polygala heterorhyncha,[1] is a species of flowering plant in the milkwort family known by the common names beaked spiny polygala[2] and notch-beaked milkwort.

It is native to southern Nevada and it is known from a few occurrences just over the border in the Funeral Mountains of California above Death Valley.

The thin, branching, thorny-tipped stems are somewhat waxy in texture and sometimes slightly hairy.

They are lined sparsely with small oval, dull-pointed leaves.

The inflorescence bears a few flowers, each with a winglike pair of bright pink sepals and a yellow-tipped central petal.
