An erect, woody, much-branched plant, at least 40 cm high, the 
branchlets densely cinereous-pilose with long spreading hairs, 
the leaves conspicuously pilose beneath on the midrib and nerves. 
Old stems about 5 mm in diameter, sparingly pilose with weak 
hairs. Leaves oblong, chartaceous, 1 to 1.5 cm long, 4 to 7 mm 
wide, narrowed to the inequilateral base and to the somewhat 
acuminate apex, the upper surface dark brownish-olivaceous 
when dry, with numerous irregularly scattered short cystoliths, 
the margin in the lower two-thirds entire, in the upper one-third 
usually with two teeth on the narrower side and three on the 
broader side, base inequilateral, one side of the lamina longer 
than the other, acute to obtuse, the narrower side acute ; stipules 
linear-lanceolate, about 1.2 mm long. Staminate heads soli- 
tary, axillary, sessile, about 4 mm in diameter, the flowers in 
each head up to 20 ; outer two bracts oblong-ovate, acute, pilose, 
2 mm long, not keeled or corniculate; bracteoles linear, ciliate, 
membranaceous, 1.5 mm long; pedicels ciliate, as long as the 
bracteoles. Sepals oblong, membranaceous, ciliate, 1.3 mm long, 
acute or obtuse, not keeled or corniculate.

In habit and general appearance this species is similar to Ela- 
tostema halconense C. B, Rob., from which it differs especially 
in the dense indumentum on the branchlets, the midrib and 
nerves beneath being pilose with long spreading hairs, and its 
distinctly smaller, less prominently toothed leaves.
