Narrow linear petioles less than 2 mm wide emerge from the center of the rosette and hold carnivorous leaves at the end.

Both petioles and the center of the rosette are densely covered in silvery dendritic hairs.

[1][2] These dendritic hairs afford the plant insulation and allow it to trap morning dew for additional moisture during the dry season.

[2][4] Drosera lanata was first formally described by Katsuhiko Kondo in 1984 when he authored three new species of the D. petiolaris complex.

[1] The type specimen was collected near Mareeba on the Cape York Peninsula on 28 March 1982.
