Eremophila foliosissima is an erect, rounded, densely foliaged shrub usually growing to no more than tall with stems and leaves covered with short, stiff, curved white hairs. Older leaves usually hang down the stem, forming a thick mat over its surface. The leaves are crowded along the stems, linear in shape with a deep groove on the lower surface, mostly long, wide, usually shiny and sticky when young. The flowers are usually borne singly in leaf axils on a hairy stalk, long. The 5
sepals are linear to narrow triangular in shape, hairy, especially on the outer surface and mostly long. The
petals are mostly long and joined at their lower end to form a tube. The outside of the petal tube and the lobes on its end are light purple to lilac-coloured and the inside of the tube is white. The outside of the petal tube and the lobes are covered with
glandular hairs, the inside of the lobes are
glabrous and the inside of the tube is filled with long, soft hairs. The 4 stamens are fully enclosed in the petal tube. Flowering occurs from July to September and is followed by fruits which are oval shaped to almost spherical and in diameter with a pale yellow, papery covering. ==Taxonomy and naming==
