Myoporum petiolatum, commonly known as sticky boobialla,[2] is a plant in the figwort family Scrophulariaceae, and is endemic to the south-east of continental Australia.

[3][4] The flowers are borne in leaf axils in clusters of 2 to 5 on stalks 4.6–8 millimetres (0.2–0.3 in) long.

There are 5 narrow triangular sepals and 5 petals forming a tube with spreading lobes on the end.

The petals are white with a slight lilac flush and purple spots on the lobes and in the tube.

[3][4] Myoporum petiolatum was first formally described by taxonomist Bob Chinnock in Eremophila and allied genera: a monograph of the plant family Myoporaceae in 2007 from a specimen collected in the Waitpinga Conservation Park.
