Phebalium verrucosum is a shrub that typically grows to a height of 5 m (16 ft) and has branchlets covered with white scales.

The sepals are joined at the base to form a cup-shaped calyx 2 mm (0.079 in) wide, warty and covered with white, star-shaped hairs.

[2][3] This species was first formally described in 1970 by Paul Wilson who gave it the name Phebalium squamulosum subsp.

[4][5] In 2014, Ian Telford and Jeremy Bruhl raised it to species status as Phebalium verrucosum in the journal Telopea.

[7] Phebalium verrucosum grows in shrubby woodland and dry rainforest on the edge of gorges and rocky stream sides near the Macleay, Guy Fawkes and Nymboida rivers.
