Aggreflorum speciosum is a species of flowering plant in the myrtle family Myrtaceaeshrub, and is endemic to eastern Australia.

It has pale bark that is shed in strips, broadly lance-shaped to elliptical leaves, white flowers arranged singly or in groups of up to three in leaf axils, and small, woody fruit that falls off when mature.

Flowering mainly occurs in August and September and the fruit is a woody capsule about 5 mm (0.20 in) in diameter with the remains of the sepals attached, but that falls off when mature.

[2][3] This species was first formally described in 1843 by Johannes Conrad Schauer who gave it the name Leptospermum speciosum in Walper's book Repertorium Botanices Systematicae.

[4][5] In 2023, Peter Gordon Wilson transferred the species to the genus Aggreflorum as A. speciosum in the journal Taxon.
