Strumaria chaplinii is a very small plant. The upper leaf surfaces are hairy. The flowers are star-shaped, with tepals that have flat faces, unlike similar species such as Strumaria discifera. Like other species of Strumaria, the flowers are borne in an umbel on long pedicels.
The species was first described as Hessea chaplinii in 1944 by Winsome Fanny Barker. It was transferred to Strumaria in 1994.
