Drosera bulbosa Hook.f. subsp. coronata R.P.Gibson from Western Australia is here described as new. It differs from D.
bulbosa subsp bulbosa and D. bulbosa subsp. major (Diels) N.G.Marchant primarily by having yellow pollen, and styles
that form an annulus (crown) around the exposed apex of the ovary. It is currently known from two locations; however it
is not considered to be under imminent threat of extinction.
