Denhamia fasciculiflora, commonly known as orange bark, is a plant in the family Celastraceae found only in Queensland, Australia.

Flowers arise from the twigs or leaf axils in short fascicles, and are very small with four or five 2 mm (0.08 in) long petals.

[4][5] The plant was first described in 1984 by Australian botanist Laurence W. Jessup as Maytenus fasciculiflora, and published in an appendix to volume 22 of the book series Flora of Australia.

[6] In 2011, American botanist Mark P. Simmons published a paper in which the Australian species of Maytenus were transferred to Denhamia, giving this plant its current binomial name.

[7] The species is found in northeastern Queensland, from Cape York Peninsula to the Atherton Tablelands.
