Zieria ingramii is a slender, spindly, aromatic shrub which grows to a height of . Its branches are ridged but unlike some other zierias, not warty. The leaves are composed of three linear to narrow elliptic leaflets with the central one long, wide and with a
petiole long. Both surfaces of the leaflets are the same colour and the edges of the leaflets are rolled under, almost to the mid-vein. The upper surface is more or less
glabrous and covered with oil
glands while the lower surface is covered with long, soft hairs. The flowers are arranged in clusters of about seven, ranging from three to thirteen in leaf
axils, the clusters about the same length as the leaves. The
sepals are triangular, about long and glabrous. The four
petals are white to pale pink, about long with their bases overlapping each other and are hairy on the outer surface and glabrous on the inner one. There are four stamens. Flowering occurs in spring and is followed by fruit which are glabrous, warty, four-chambered
capsules containing dull black seeds. This zieria is similar to
Z. aspalathoides but that species has fewer but larger flowers in each group and shorter, warty leaflets. ==Taxonomy and naming==
