Spyridium stenophyllum is a sticky shrub that typically grows to a height of up to 1.2 m (3 ft 11 in) and has densely hairy young stems.

The edges of the leaves are turned down or rolled under, the lower surface densely covered with star-shaped hairs.

[2] This species was first formally described in 1858 by Siegfried Reissek who gave it the name Trymalium stenophyllum in the journal Linnaea from specimens collected by Johann Friedrich Carl Wilhelmi at "Point Boston".

[2][3] In 2012, Jürgen Kellermann and William Robert Barker changed the name to Spyridium stenophyllum in the journal Muelleria.

stenophyllum is distributed around Arno Bay, along the east coast of the Eyre Peninsula, and in scattered place further inland.
