Phebalium lowanense is a slender shrub that typically grows to a height of and is more or less covered with silvery or rust-coloured scales. The leaves are linear, long and about wide but with the edges strongly rolled under, so that they appear cylindrical. The upper surface of the leaves is
glabrous and slightly scaly, and the lower surface is covered with silvery scales. The flowers are yellow and arranged in umbels on the ends of branchlets with up to six flowers, each flower on a thick
pedicel long. The
sepals are long and joined for about half their length, and densely covered with silvery scales and star-shaped hairs. The
petals are egg-shaped, about long and wide, covered with silvery and rust-coloured scales on the back. Flowering occurs August to September. ==Taxonomy and naming==
