This uncommon plant is a small shrub growing up to about half a meter tall with slender, spreading, woolly branches. There are sparse leaves along the stem, usually found in clusters at the tips and branching points. The leaves are widely lance-shaped and coated in white woolly fibers.
The top of the stem is occupied by the branching inflorescence which bears clusters of very woolly, star-shaped white flowers each under a centimeter wide.
