Glycocystis beckeri is the only species of the flowering plant genus Glycocystis in the family Scrophulariaceae and is endemic to the south west of Western Australia. It is a shrub, similar to others in the genera Eremophila and Myoporum but is unusual in that it produces very large amounts of sticky, sweet-smelling resin produced by raised glands which cover the entire plant, except for the petals. It has been suggested that the resin traps insects which the plant uses as a source of nitrogen.
