Dasymalla terminalis is a rigid shrub which grows to a height of with its branches densely covered with short, ash-coloured hairs. The younger branches and leaves are covered with a more yellowish layer of hairs. The leaves are egg-shaped, long, wide, with those near the ends of the branches crowded together. The flowers are white and arranged in upper leaf
axils in groups of up to three on a stalk long and covered with short hairs. The flowers are surrounded by leafy
bracts and
bracteoles which are covered with
glandular hairs, especially on their edges. The five
sepals are long, linear in shape with hairy margins and joined to form a short tube near the base. The five
petals are joined to form a tube long and mostly
glabrous except for a dense hairy ring inside the tube, below the
stamens. There are five lobes on the end of the petal tube, the lower one elliptic to almost round in shape and slightly larger than the other four lobes. ==Taxonomy and naming==
