Etymology:
Melaleuca is derived from the Ancient Greek μέλας (mélas) meaning "dark" or "black" and λευκός (leukós) meaning "white"

The spikes are 20–30 mm (0.8–1 in) in diameter with 10 to 40 individual flowers
The petals are 2.6–4.2 mm long and fall off as the flower ages and there are 48–67 stamens in each flower
Flowering occurs mainly from October to January

Taxonomy and naming
Melaleuca paludicola was named in 2006 by Lyndley Craven in Novon when he transferred Callistemon sieberi to the present genus
Callistemon sieberi was first formally described by botanist Augustin Pyramus de Candolle in 1828 in Prodromus Systematis Naturalis Regni Vegetabilis
An earlier, alternative name (taxonomic synonym) for the species was Callistemon paludosus and the present name was chosen to link with the earlier one
Callistemon paludosus is regarded as a synonym of Melaleuca paludicola by the Royal Botanic Gardens, Kew
Use in horticulture
Melaleuca paludicola is sometimes cultivated as Callistemon sieberi
An alpine form is a smaller, denser, rounded shrub suitable as a more formal plant
